feature

Metal hose with end fittings nipple with external thread corresponds to a series ST040. Designed for quick joining of pipelines. Made with external single or double steel braid. Mounted on the ends of the fittings with external thread, allowing to carry out sealed joining. Connecting threaded fittings nipple is made of steel Ст20сп.

Thanks to the steel braided sleeve can withstand the highest pressure. The number of braids depends on the working pressure. Braid are made of stainless steel 12KH18N10T, AISI 304, AISI 321.

Quality metal hose have a number of requirements, in particular should not be dangling wires, mechanical damage, penetrating defects. These metal hoses are produced with cross-sections up to 300 mm length from 25 cm up to six metres.

application

Metal sleeve with male thread is used at temperatures from cryogenic to +600 degrees and an operating pressure from vacuum to 350 Bar. Used in all industries for pumping fuels, lubricants, steam. Working in a wide range of temperatures and pressures. Metal sleeve with an external thread, and compensate for axial thermal expansion and absorb vibration of operating equipment, extend the life of the pipelines. The service life of a flange of metal hoses depends on the intensity of load cycles, temperature and pressure, oscillation amplitude, the displacement of the metal hose, the bending radius.

installation

Installation works with metal hose, with threaded coupling nipple, do not have too much difficulty. This connection is reliable and provides the possibility of repeated Assembly and disassembly. In the area of the fitting should be neutral areas that are not subject to deformation during operation. The installation provides a minimum length loose sites — no more than two meters. For supports use clamps or special trays.
