The testing equipments for high and low temperature testing, peeling testing, blasting testing.
Test benches are used for reliable and ecological tests of finished workpieces – which is also required for reasons of product liability.
Hose Crimpers for production environments - Innovative, productive and durable.
Tensile strength test equipment controlled by computer provides detailed analysis including tensile strength and elongation.
Shore durometer clearly shows the hardness of the rubber. Harder rubber has good resistance against abrasion.
Quality control departmen mainly responsible for product quality testing，provide production technical support to production department，ensure that every product provided to the customer is safe and reliable.
Hydraulic rubber hoses are getting popular in conveying hydraulic fluids with pressure for their great flexibility, affordability and durability. General speaking, a hydraulic hose consists at least three parts - an inner tube which carries the fluid, a reinforcement supporting the tube and an abrasion and ozone resistant cover.
Inner tube should be compatible with the fluids it will carry and have some flexibility. Common materials of making tube are synthetic rubber, thermoplastics and PTFE. They are friendly to most petroleum- and water-based hydraulic fluids. If the tube reacts with the fluids, the hose will be prone to leakage or cause incidents. When you are not sure about the relationship between the tube and the media to be carried, consult us and we will come back to you soon.
Hose reinforcement is taken as a sheath protecting fragile tube. It is used to be multiple layers of braided textile, wire or spiral-wound wire. They can support different grades of pressures according to your applications. Commonly, textile reinforcement, whether single or double layers, is ideal for tight routing and low pressure system such as return and suction systems. Braid wire and spiral wire are usually for high working pressure. If the system has severe requirement of impulse fatigue, spiral wire reinforcement is the priority.
Cover is the first barrier to guard the hose. It is usually made of abrasion and weather proof synthetic rubber to resist oils, chemicals, ozone and other adverse factors from outside environment.
Seven effective steps to help you select proper hydraulic hose:
Hydraulic hoses are designed to carry hydraulic fluids often with high pressure and high temperature. They are very important elements for hydraulic systems. Not all hydraulic hoses are suitable for all purposes. There is a 7 alphabet principle to resolve your problems of hydraulic hose problems.
Inappropriate hose inside diameter will cause pressure loss and create excessive heat. Dash number refers to sixteenths of an inch standing for the size and coupling and makes the measurement easy to remember. Although Hose O.D. will not affect the pressure and heat, it is still an important factor when hose routing is tight.
Fluid temperature and ambient temperature should be considered. Fluid temperatures, whether maximum or minimum, should be kept in a reasonable range. When the fluid is far higher or lower than specified operating temperature, the tube will degrade materially. Ambient temperature also concerns about the life of the hose, especially the cover and reinforcement. Once the cover is not workable, reinforcement is exposed to the environments, so the potentiality will be increasing.
Understand the applications are very helpful the hydraulic hose selection. You can ask yourself or your customer some questions such as where are the hose used?
Medias including oils, hydraulic fluids and special chemicals directly contact with the tube. You must be sure that the tube can be compatible with the fluid, or the hose will fail in a short time and cause unnecessary accidents.
Operating pressure should be lower than maximum working pressure and the hose is not suitable for working under maximum pressure for a long time. Surge pressure, which is far higher than normal operating pressure, should be given enough attention to. If the pressure surge is very harmful, spiral wire hydraulic hose may be your premium choice.
Couplings of hydraulic hoses are not interchangeable. Improper coupling also shortens life service period. Consult the manufacturer for suitable coupling.
Once the bore size is determined, consult the chart to determine fluid rate and velocity. Inquiry for Our Product.
If customers have special requirements for products. The following instructions should be provided in the order contract:
Type of hose
Length of hose
Type of connector
Nominal diameter and inner diameter
Use medium and temperature, pressure range and other specific use environment, the more detailed the better.
Test, inspection standards and other requirements
We can configure all kinds of connectors according to the special requirements of customers. If the type of hoses are determined by the customer, the customer should correctly explain the meaning and requirements of the type and sign the contract under the condition that both the supplier and the demander have the same understanding.
