【Product Basic Overview】

Flange type metal hose is an indispensable special flexible compensation pipe fitting in modern industrial pipeline engineering, mainly used for flexible pipeline connection, thermal expansion and contraction displacement compensation, equipment operation vibration absorption and pipeline installation deviation straightening. It solves common pain points of ordinary hard pipe connection such as strong rigidity, poor seismic performance, easy deformation and cracking at high temperature, poor sealing and leakage, and difficult butt installation due to pipeline dislocation. This product has two common structural types: ZJGH-A/F flat welding flange at both ends and ZJGH-A1/F1 flat welding flange and loose flange at one end. Adopting composite structure of precision stainless steel bellows and high-strength steel wire braided outer layer, formed by integral flange welding process with flat and firm welds without pinholes and virtual welding, featuring excellent pressure sealing performance. Adapting to complex working conditions with alternating high and low temperatures, compatible with long-term conveying of various liquid and gas media, acid and alkali corrosion resistant and rust free, no deformation, net shedding or medium leakage during long-term use, suitable for various harsh industrial environments and ensuring safe, stable and long-term operation of pipeline systems.

【Product Model Structure & Core Material Description】

1. Main Fixed Model Configuration: ZJGH-A/F type with flat welding flanges at both ends, fixed welding between flange and hose body with high butt strength and good pressure sealing performance, suitable for permanent installation of fixed pipelines; ZJGH-A1/F1 type with flat welding flange on one end and loose flange on the other end, the loose flange can rotate freely to adjust the angle, adapting to pipeline installation dislocation and butt hole deviation with stronger installation compatibility. 2. Core Main Material: Made of high-quality stainless steel base material, optional industrial grade 304 and 316L stainless steel, corrosion resistant, high temperature resistant, antioxidant and rust free, suitable for long-term use in complex working conditions such as acid, alkali, high temperature and humidity. 3. Internal Pipe Structure: Inner precision stainless steel bellows with good flexible scalability, small bending radius and large displacement compensation; outer high-strength stainless steel wire braided reinforcement layer improving the overall tensile, pressure, impact and deformation resistance of the hose with explosion-proof and crack-resistant stable structure. 4. Flange Connection Structure: Flat flange disc with standard bolt holes and exquisite welding process, high strength at the joint of flange and hose, no welding detachment or leakage under long-term pressure, convenient for disassembly, maintenance and reuse.
