High Pressure Resistant Ss Metal Flexible Hose for Oil & Gas Applications

Product Description

Description For  Metal hoses

Metal hoses are core flexible components for pipeline connections in modern industrial and civil fields. Combining the sturdiness and durability of metal materials with the flexibility of pipelines, they can meet the medium transmission needs under complex layouts and harsh working conditions, and are widely used in various industries.

The structure of a metal hose mainly consists of three parts: inner tube, middle layer and outer sheath. The inner tube is mostly made of 304/316L stainless steel , which ensures the tightness and corrosion resistance of medium transmission. The middle layer is a spiral steel wire mesh structure, which greatly enhances the pressure resistance of the hose. The outer sheath is made of stainless steel braided layer or PVC coating, which can effectively resist external wear and impact. In terms of material selection, 304 stainless steel is suitable for conventional scenarios, while 316L stainless steel, with stronger corrosion resistance, is used in corrosive environments such as coastal areas and chemical industry.

Product Advantage

Core Advantages of Metal Flexible Hoses

Wide temperature resistance range: which allows stable operation between -196℃ and 600℃

Strong corrosion resistance:as the austenitic stainless steel material can resist erosion by various acid-base corrosive media

Excellent flexibility:the thin-walled stainless steel tube is formed by hydraulic pressure, with a small bending radius, which can flexibly adapt to complex pipeline installation layouts

High pressure resistanc:with the protection of braided mesh sleeve, the working pressure range covers PN0.6 - 32.0MPa, up to 42.0MPa

Reliable sealing performance:relying on advanced connection technology and sealing materials to ensure zero leakage in medium transmission.

Q2: What is the temperature and pressure range of your metal hoses?
A2: Our metal hoses have an excellent temperature resistance range of -196℃ to 600℃, which can adapt to extreme low - temperature cryogenic media and high - temperature steam transmission. The working pressure covers PN0.6–32.0 MPa, with the maximum pressure up to 42.0 MPa. The specific pressure resistance depends on the product specification and structural design, such as braided metal hoses having higher pressure resistance than ordinary corrugated hoses.
