Hydraulic Hose Fittings Manufacturer in China

Reliable Materials: We rigorously select our raw material suppliers and accept only high quality carbon steels with high intensity and corrosive resistance performance. We select FKM or NBR O-rings and sealings with certified supply chain include ISO 9001-audited mills to ensure the sealing under high temperature or pressures. Each metal billet undergoes spectrometer testing for tensile strength (≥600MPa), yield stress(≥355), elongation(≥16) and reduction(≥40) before production.

Engineered Manufacturing: Every hydraulic fitting is precision-machined using CNC lathe machines for thread and inside bore to ensure the tolerance ±0.1 mm and validated against Parker Hannifin and Eaton's benchmarks. For hexagon or flange clamp we have machines for customized process.

The hydraulic hose fittings consists of a metal pipe body, a stainless steel wire cap and a fitting. In the ship piping system, it is mainly used for the connection between the pipeline and the equipment. It can compensate for a certain relative displacement and play a role in reducing vibration and noise. However, if the selection is improper, it will not only fail to achieve the effect of vibration isolation and noise reduction, but will also cause pipeline leakage and even equipment failure due to damage to the fittings.
The selection of metal hoses mainly includes the correct selection of parameters such as diameter, connection type, working pressure, temperature correction, minimum bending radius and hose length. The diameter, connection type and working pressure directly depend on the requirements of the pipeline system, and generally there will be no problem. The temperature correction and minimum bending radius are fixed for the product and are given by the manufacturer. The problem often encounter is the selection of the length of the fittings. A fitting that is too long will cause instability, increase flow resistance, and cause additional mechanical damage and vibration problems. A fitting that is too short may not achieve the purpose of compensation, vibration reduction and noise elimination, and may also cause excessive bending stress and affect its life.

Each hydraulic must pass 3 quality test before delivering to clients. First the need to pass the multiple tests including hardness test and pressure test.
 

The excellent performance of Haodema hydraulic fittings begins with high-quality roughcast forging technology. We use high-strength alloy steel and precision forging technology to make the internal grain structure of the metal denser, greatly improving the mechanical strength and impact resistance of the product.

During the forging process, we use advanced die forging and cold heading technology to ensure that the roughcast size is accurate and free of internal defects, laying a solid foundation for subsequent machining. Each forged roughcast undergoes rigorous flaw detection and mechanical property testing to ensure that its hardness and toughness reach the industry-leading level.

Haodema's forging process not only optimizes material utilization, but also gives the product higher reliability and durability. From raw materials to finished products, we forge every detail with ingenuity, just to deliver high-quality products to our customers.
