How to properly use hydraulic hose to extend the service life

Use Techoses hydraulic hose assembly to get the best use of life

The service life of the hydraulic hose assembly depends on its conditions of use.

Check the hose assembly in use for leaks, kinks, outer blistering, abrasions, abrasions or other damage. After the assembly is damaged or worn, it must be replaced immediately.

The following measures can be used to extend the service life of the assembly:

1, hose assembly installation: hydraulic hose assembly should be installed in line with SAEJ1273 hydraulic hose on the direction and layout of the relevant standards to ensure that the hose assembly is properly used.

2, the working pressure: hydraulic system pressure should not exceed the rated working pressure of the hose. Stresses or peaks above the rated working pressure are extremely damaging, and must be taken into account when selecting a hose.

3, the minimum burst pressure: the product catalog referred to the burst pressure is limited to destructive testing to determine the purpose of design safety factor.

4, the temperature range: Do not exceed the recommended limit temperature conditions (including internal and external temperature) under the use of hose. If the hydraulic fluid used contains emulsion or solution, please refer to the relevant technical data. Regardless of the temperature range of the hose, no more than the maximum temperature recommended by the fluid manufacturer.

5, fluid compatibility: hydraulic hose assembly (inner layer, outer layer, reinforcement layer and hose connector) must be compatible with the use of fluid. The proper hose must be used because the chemical properties of the phosphate and petroleum-based hydraulic fluids are quite different. Many hoses are suitable for one or more fluids but are not suitable for all fluid types.

6, the minimum bending radius: the hose can not be bent to less than the recommended minimum bending radius, nor to allow the hose to withstand tension or torque, which may make the reinforcement layer to withstand excessive stress, greatly reduce the ability of the hose to withstand the pressure

7, hose size: hose size (diameter) must be able to handle the required flow, at a specific flow, if the diameter is too small, will cause excessive fluid pressure and heat, resulting in damage to the inner layer.

8, the hose to the layout: the hose to be restrained, protected or guided (if necessary, the use of pipe clamp), in order to minimize excessive deflection, jitter or contact with moving parts or corrosive caused by the risk of breaking the ring. Determine the appropriate length of the hose and the form of the joint to prevent wear, avoid contact with sharp objects and produce twist, so as to prevent leakage of the connection.

9, the length of the hose: to determine the correct length of the hose should be under pressure, the machine vibration and movement, as well as hose assembly wiring length taken into account.

10, Hose Application: Select the appropriate hose according to the specific application. Oil application (Orientflex SAE R4), special fluid or high temperature performance is the need for special consideration the use of special hose application examples

The Differences Between PU Hose and PVC Hose

PVC hose and PU hose are two very common hose production materials, all in all walks of life have a wide range of applications. But the specific performance of these two hoses are very different, the following is the most important three points:

pvc-pu-hose

1, the temperature is not the same, the general temperature of 65 ℃ PVC hose, and ordinary PU hose can reach the maximum temperature of 90 ℃.

2, wear resistance is not the same, PU material hose more wear-resistant, so the suction particles large and high wear and tear of the material, PVC hose life is very short.

3, the steel hose for example, the same wall thickness, the same wire spacing, PU material will be more soft, PVC will be relatively hard, unless the plasticizer inside the PVC to add a lot.Plasticizer is a kind of additive that makes PVC hose soften, but the current food standard has strict requirements for plasticizer content, so soft PVC hose, plasticizer content is far from environmental requirements.

Oil & Gas Exploration Hoses for Industrial

Common applications include:
Petroleum-based liquids, non-potable and salty water, fracture and sludge solutions
Rotary drilling: portable drilling, work platforms and thin drilling rigs

Avoiding The Dreaded Recall With Sanitary Hose Assemblies

How stainless steel sanitary hose can keep your food and beverage plant compatible

When it comes to opening the soda can or swallowing an aspirin, most people usually do not think twice about what it takes to make that product. However, food and beverage safety is increasingly becoming a hot topic in the media, partly fueled by more than 1,500 outbreaks of foodborne illness that resulted in 29,444 illnesses in 2009-2010. By 2013, nearly 300 food products were recalled by the FDA for a variety of reasons for foreign objects, such as fragments of glass or metal, to bacteria.

A high quality stainless steel sanitary hose, such as those made by TecHoses Hose, can make a difference, not only for the final consumer, but also for the manufacturer. The PTFE hose with a stainless steel braid and a silicone sleeve, such as the Tecos Hose ST-Flex, take it a step further as an excellent food grade hose, as the outer casing is also non-polluting and easy to clean. clean. Although compared to rubber or silicone hose, stainless steel sanitary hose produces higher purity, real benefits include:

Flexibility – the stainless steel sanitary hose is flexible, providing greater range of motion and mobility within the manufacturing environment.

Higher Pressure Resistant – Stainless steel sanitary hose can withstand higher pressure and other high pressure conditions, which is important for food and beverage manufacturing.

It ensures sanitary compliance – most importantly, stainless steel sanitary hose, including those with PTFE core, complies with FDA FDA 21CFR177.1550, USDA and 3-A sanitary standards. It leaves no taste or order in the food or beverages it transports, meeting or exceeding these standards by these governing organizations.

Easy to clean – Since PTFE hoses are used heavily in sanitary manufacturing processes, they are designed for easy maintenance, cleaning and drainage. This is the essential part in preventing bacteria that can lead to contamination and results in food souvenirs.
Long lasting – stainless steel sanitary hose will not deteriorate in service, saving manufacturer’s downtime and replacement costs.

Sanitary connections for hose connections

Stainless steel sanitary hoses require a tight, secure, non-leaking sanitary fitting such as Tri-Clamp® and Tri-Clover®. JIC or NPT fittings, which are made of 316 stainless steel, are another popular choice for food and beverage manufacturing. Sticky, moist or even dangerous conditions – not to mention product loss – could turn out differently. When ordering sanitary accessories, make sure your supplier meets or exceeds your sanitary requirements, as well as providing a certificate of compliance and labeling for traceability.

The food and beverage industry is not just the benefits of stainless steel sanitary hoses. They are also ideal for the manufacture of pharmaceuticals, as well as for the manufacture of semiconductor pellets and for chemical processing, where sanitary transfers require clean and easy to clean sets of hoses.

Ensure Chemical Hose Assembly Materials are Media Compatible

When selecting your hose assembly, it is always necessary to ensure the suitability of the material with the chemical, gas or granulate that will flow through it during its process. This includes checking the materials of the hose fittings for chemicals as well. If a PTFE coated hose is an excellent material to process your media, it may not be compatible with the selected carbon steel hose fittings for your chemical hose assembly. You should then consider other materials for hose fittings, such as stainless steel (SS), brass or hastelloy. High purity processes and other chemical applications may require PTFE encapsulated SS hose fittings. Whatever medium you are going to use, make sure it is compatible with the chemical resistant hose you select.

Chemical-Hose-Assembly

Towards the top right of this page is our chemical hose compatibility tool that you can use to check that the materials are suitable for the media you want. Click the arrow to the right of the “select chemical” field to display the list of chemicals. Then click on the chemical to extract a table that shows four different types of compatibility for the common materials we work with when making chemical hose assemblies. Compatibility tables show grades for media interaction with PTFE, 316 SS, 304 SS, carbon steel and brass. The most common assemblies made by the TecHose are PTFE coated hoses with a 304 SS outer braid for the reinforcement. 316L stainless steel hoses and hose cuffs 304 SS. If your specific chemical, gas, or granulate is not listed in the chemical hoses compatibility charts, please send it to us through our Contact Form and we will help you determine which chemical resistant hose configuration is best.

 

Why are PTFE lined hoses your chemical hose of choice?

PTFE lined hose with SS braid reinforcement is extremely flexible and versatile for use as a chemical hose.

They are easy to drain and can handle a variety of chemical fluids, gases and granulates due to their chemically resistant properties. Best of all, they have a non-aged surface, resulting in a durable and durable chemical hose solution for your manufacturing and control process. Read more in our Blog article on chemical hoses.

Special Attentions of Hydraulic Rubber Hose Using

Hydraulic hose must be used in a right way and there are the attentions

Considerations of using hydraulic hose

  1. Must be used in the recommended range of temperature and pressure
  2. Hose will be expanded and contracted with internal pressure, please cut the hose into slightly longer than your need length.
  3. When pressure is applied, please slow switch any valve to avoid the shock pressure.
  4. Use hose in its bending radius, otherwise it will cause broken, reduce the resistance to pressure hose.
  5. Using powder, granules according to conditions may have wear phenomenon, please enlarge hose bend radius as far as possible.
  6. Do not use in extreme bending condition when it’s near the metal parts.
  7. Do not direct contact or close proximity to the fire hose.
  8. Please do not use vehicle to step on rubber hose.

For fluid:

  • The hose that to be used to apply to the fluid being conveyed.
  • Before he hose is used for oil, power, toxic chemicals and strong acids or alkali, please consult the product provider.

Precautions of hydraulic hose when it is assembled

  • Please choose the suitable size of hose fitting for hose.
  • When the joint tube end portion is inserted into the hose, paint the hose and pipe tail in oils, do not roast with fire. If it’s unable to insert, heat the hose with hot water and then it will be available insert into the connector.
  • Please make sure the serrated tube tail portion of the connector is completely inserted into the hose.
  • Do not use a joint that can be pushed into for one time, it may cause hose rupture.
  • Please avoid using excessive ligation wire, please choose a special sleeve or cable tie.
  • Avoid using injurious or rusty joints.

Check notes:

  • Check before using: before using the hose please make sure the hose appearance has no abnormal trauma, hardening, softening, and discoloration.
  • Check regularly: during use of the hose please be sure to implement regularly check for once a month.

Security matters:
The operator must wear safety protective clothing, including gloves, rubber boots, eye shields, and the equipment to be used mainly to protect the safety of the operators.
To ensure the work zone is safety and orderly.
To check each hose joint is firm.
When not in use, and do not make hose in pressure state. Shut off pressure to extend the service

The Detailed Method of Repairing a Hydraulic Hose

The detailed description of instruction to repair a hydraulic hose by yourself

Problems arise frequently with the hydraulic hoses in hydraulic systems. And a common problem is leaking hydraulic oil, so if you experience this problem, the only solution is to replace the hydraulic hose. You can make the change by yourself and it allows significant savings in technical service. Therefore we invite you to browse our recommendations for replacing a hydraulic hose.

Leak location
Turn hydraulic unit and determine the location in the leaking hydraulic fluid. It is easy to locate the leak if your traffic is on the dry surface. Make a mark in the part of the system in order to understand exactly what kind of hydraulic hose needs to be replaced.

Pressure reduction
Release the pressure in the hydraulic system. Turn off the hydraulics and compressed air control switch to the neutral position, which in turn will release the pressure from the system, and will remove the damaged hydraulic hose.

Preparation
Prepare a suitable container and place it directly under the hydraulic hose, which you plan to relax. Loose the fitting with a wrench. Do carefully, as the hydraulic oil may still remain in the hydraulic hose. In some cases you need to remove some of the equipment that will prevent the replacement of the hydraulic hose.

Setting hydraulic hose
Remove the damaged hydraulic hose before you install a new hydraulic hose, carefully remove debris from the fittings and aprons. Install a new hydraulic hose in place.

Test hydraulic hose
If you have enough hydraulic oil in the hydraulic system, observe a few minutes for leaking hydraulic oil in other places. If not, add the hydraulic oil in the hydraulic tank.  Replacement hydraulic hose usually solves the problem of leakage of the hydraulic system. Remind that to replace the hydraulic hose must be used exactly the same type of hydraulic hose, as well as remote. Steps to replace the hydraulic hose are quite simple and you are able to do them for a few minutes. To avoid this problem with the hydraulic hose in the future, routine maintenance of hydraulic equipment is necessary in a timely manner.
