In 1993 China has issued national standard "general technical conditions of corrugated metal hose" (GB/T14525-93). Corrugated metal hose using the tube has two kinds, one kind is spiral corrugated pipe; another is the annular corrugated tube. Spiral corrugated pipe metal hose connection: metal hose connection manner, divided into the flange threaded connection, quick connector, small caliber metal hose by wire...
Metal hose is connected component is important in engineering and technology, formed by the combination of corrugated flexible pipe, nets and joint. In all kinds of gas, the infusion pipe system and temperature, length, position and angle compensation system as the compensation components, sealing components, connecting element and damping element, used in the fields of aerospace, petrochemical, mining, shipbuilding, machinery electronic medical, textile electronic, energy construction.
In 1993 China has issued national standard "general technical conditions of corrugated metal hose" (GB/T14525-93).
Metal hose using austenitic stainless steel material or according to user requirements for materials, with soft, excellent corrosion resistance, high temperature resistance (- 235 ℃～ + 450 ℃), high pressure (up to 32MPa), in the pipe can be connected to any direction, is used for temperature compensation and vibration absorption, reduce noise, changing the medium conveying direction, eliminating the mechanical displacement of pipeline or pipeline and equipment room etc., is particularly suitable for the flexible joint double flange of corrugated metal hose to the displacement, vibration pump, valve etc..
Corrugated metal hose using the tube has two kinds, one kind is spiral corrugated pipe; another is the annular corrugated tube.
Spiral corrugated pipe
Spiral corrugated pipe is a corrugated spiral arrangement was the tube shaped shell, between two adjacent corrugated a helix angle, all the bellows can be connected by a spiral line.
Metal hose connection:
Metal hose connection manner, divided into the flange threaded connection, quick connector, small caliber metal hose by threads and fast connection, the larger diameter generally use the flange connection.
Hengshui Shuangxing rubber products Co., Ltd. was founded in 1991, is the earliest, the plant in North China is the largest hydraulic pneumatic hose professional production enterprises, in 2000 passed the ISO9001 quality system certification.
