Metal hose with fittings for welding
Metal hose with fittings for welding are flexible pipelines. Are produced depending on pressure 16 — 280 ATM., diameter 6−250 mm and a length of 600 cm (whole sleeve). The hoses are of greater length, but welded. Component of flexible metal hose made from stainless pipe billet by mechanical or hydraulic forming of corrugations, which is the analogue of the spiral wrap of UAP Gidravlika FGUP 8Д4, Н8Д0 and 4655А. manufacture of metal hoses meet all the technical conditions and GOST.

— Metal hoses with end fittings are manufactured from flexible one-piece part, the length of which is 25 m.
The power component of the structure of metal flexible hose is braided, do not interfere with the bending sleeve, perceiving radial and axial loads. Braid is made of stainless steel wire. The number of braids on the metal sleeve depends on the size of its working pressure. When choosing a metal hoses of high pressure main parameters are the pressure of the working medium and temperature. Need to know what the difference between working pressure and bursting pressure of the hose varies not less than three times. It is very important in the production of metal hoses — compliance with welding technology joining stainless steel flexible hose to a pipe fixed part, since the welds have to withstand a given pressure. For these purposes, technology is used argon welding and double welding seam. At the end of the work related to the joining (welding) sleeves, it is necessary to conduct a hydro test (leak test), in order to prevent leakage of the working environment.
Metal hose series 4655А «weld»
Typically, they are used for the joining of pipelines and stationary units. Correct installation and high quality welding allows metal hose to serve in the node to the end of operation of the pipeline or host. In the process vibratory loads in the docking locations of the pipelines and to operate in aggressive environments used SRGS — tight metal hose high pressure corrugated sheath series 4655А. Welded hermetic metal hose stainless steel (SRGS) are produced by coagulation profiled steel tape in a spiral with a further suture welding.
Metal hose series Н8ДО.449.020 «weld»
These hoses are made from shell-type RGT (sealed Sleeve pipe), metal hose with such a sheath effectively installed in the units and the pipeline with high vibration loads, high pressure.
Metal hose series 8Д4.498.469 «weld».
This series spiral wrap is made from a shell type LTA (sealed sleeve with a helical corrugated pipe). They are resistant to low and high temperatures and can be used at working critical pressure up to 350 ATM. Main criteria increase the service life of the metal hoses is professional installation and proper operation of the pipeline.
