【Product Basic Overview】

Threaded type metal hose is a flexible metal connecting pipe specially designed for threaded butt installation of small-diameter industrial pipelines. Its core functions include pipeline thermal expansion and contraction displacement compensation, equipment operation vibration and noise reduction, pipeline installation deviation correction and rigid pipe connection buffer protection. It solves common industrial pain points such as easy cracking of ordinary rigid pipe connection, complicated welding installation process, poor sealing and leakage, easy aging and damage in high and low temperature environments, and high pipeline vibration noise. This product adopts integrated precision bellows forming process with standard internal and external threaded joints at both ends, no on-site welding needed, installation completed directly by tightening with a wrench for high construction efficiency. Two stainless steel materials are optional: 304 civil general grade and 316L corrosion-resistant industrial grade. The overall structure is compact and firm with welds without pinholes and virtual welding, excellent pressure sealing performance, no rust, delamination or pipe bursting during long-term conveying of water, gas and conventional fluid media, suitable for long-term stable operation of small pipeline systems in indoor equipment rooms, supporting equipment, high and low temperature workshops and other conventional industrial service environments.

【Product Structure & Core Material Description】

1. Inner Stainless Steel Bellows Main Body: Precision stamped and formed from 304/316L stainless steel with good flexibility and small bending radius, excellent telescopic deformation ability, effectively compensating pipeline thermal expansion and contraction displacement, buffering equipment operation vibration, good flex fatigue resistance and not easy to break, adapting to frequent deformation working conditions. 2. Outer Stainless Steel Wire Braided Reinforcement Layer: Densely woven and reinforced with high-density stainless steel wire, improving the overall tensile strength, pressure resistance and impact resistance of the hose, protecting the inner bellows from external tension and wear, explosion and deformation resistant, no deformation or net shedding during long-term use. 3. Threaded Connection Joints at Both Ends: Standard national standard internal and external thread joints with regular thread tooth shape and tight occlusion, achieving zero leakage sealing effect with metal sealing gaskets, no welding installation required, convenient disassembly, maintenance and reuse. 4. Core Material Selection: 304 stainless steel with high cost performance, rust resistant and general aging resistant, suitable for ordinary water heating and electromechanical general working conditions; 316L stainless steel with stronger acid and alkali corrosion resistance and oxidation resistance, suitable for special working conditions of slightly corrosive fluids and high-temperature precision equipment.
