Metal hose is an important engineering technology connecting member corrosion metal hoses, corrugated flexible pipe, and fittings combination of nets. In a variety of gas, fluid piping systems and length, temperature, position and angle compensation system as a compensation components, sealing elements, connecting elements and damping element marine metal hose, used in aerospace, petrochemical, mining and electronics, machinery and shipbuilding, medical and health, textile electronics, energy, construction and other fields. Was released in 1993 our national standard "corrugated metal hose general technical conditions" (GB / T14525-93). Austenitic stainless steel metal hose or user requirements by manufacturing materials, with excellent flexibility, corrosion resistance, high temperature resistance (-235 ℃ ~ + 450 ℃), high pressure resistance (up to 32MPa), the tube path can be connected to any direction for temperature compensation and absorb vibration and reduce noise, change the direction of media delivery, eliminating the mechanical displacement pipes or between pipes and between devices such as dual flange has a displacement of corrugated metal hose, vibration pumps, valves and other flexible joints is particularly applicable. Bellows metal hose, there are two, one is a spiral bellows; the other is a ring-shaped bellows. Spiral bellows spiral corrugated bellows is spirally arranged tubular housing, between two adjacent corrugations have a helix angle oxygen metal hose, all corrugations can be connected by a spiral . Toroidal bellows bellows corrugated ring was closed annular tubular housing, between wave and wave series made from corrugated ring. Toroidal bellows formed from seamless pipe or welded pipe processing. Constrained by the processing method, compared to spiral bellows metal hose, its single-tube length is usually shorter. Advantages toroidal bellows is elastic, small stiffness. Visual inspection of hoses and weld sealing surface without cracks, pores, slag, weld spatter, and pits, visual or visual inspection with appropriate multiples magnifying glass. Inner and outer surface of the hose should be clean and dry, not allowed to have rust, iron and other residues exist. Nets should fit bellows, bellows surface bumps are not allowed welding slag and other defects. The number of broken wire mesh and steel should meet the standard requirements.
