The hermetically sealed stainless steel hose is a complex product that consists of a corrugated hose made of high-alloyed corrosion-resistant austenitic steel and hose fittings that determines the way the hose is attached to the pipeline system. The hose is covered with one or more layers of wire braiding, which is made of the same corrosion-resistant steel as the corrugated hose. This material has a high degree of cold and heat resistance, as well as a high level of resistance to aggressive materials.
As the end fittings, a fitting-nut or male fitting, flange, welded nipple, nipple for crimping by clamp, nipple with external thread, quick-release coupling, conic threaded connection and elbow can be used. In other words, any type of end fittings that can provide a hermetic, convenient and reliable fastening to the pipeline system. It must be taken into account that the working pressure of the armature, and of the hose, must coincide with the working pressure of the whole pipeline system. It is also important to remember that at high temperatures (> 300 ° C), do not use end fittings with paint or galvanized coatings that may contain lead, zinc and other non-ferrous metals, because they can cause embrittlement of austenitic steel.
You can buy metal hoses in Kazakhstan and Russia.
The design of metal hoses from stainless steel provides a strong and flexible hermetic connection that compensates water hammering, temperature expansions, vibration, systematic changes in pressure of pipeline systems. Such products supply a working, cooling or other process liquid to the movable executive element of machines or mechanisms performing reciprocating and other complex movements that are caused by the technological process.
The presence of a multilayer wire braid guarantees the uninterrupted operation of the hose at high excess pressure (up to 300 - 400 bar).
High-alloyed corrosion-resistant austenitic steel (AISI group 300), which is highly resistant to aggressive liquids, allows the use of hermetic metal hoses in the chemical and oil and gas industries, as well as in areas of production where it is required to transfer an aggressive materials or to protect the hose from it. The strength and tightness of such hoses determines their application in areas where explosion protection of cables or wires is required.
High cold and heat resistance of steel, guarantee an excellent performance of the hose in the temperature range from-250 ° C to + 700 ° C, therefore such products can be used both in the cryogenic sphere and in the high temperature range.
The flexibility of the metal hose and the smallest minimum bending radius for an almost unlimited maximum length (a separate hose can be up to 50 m in length, but thanks to a quality fittings it can be connected in lengths of a kilometer) allows the hose to be used as a mobile pipe line.
High-pressure metal hoses are produced in a large nomenclature of nominal diameters - from 6 mm to 300 mm.
Our company manufactures stainless steel hoses from DN 6 to DN 300 mm in the entire gradation range, with operating pressure up to 300 bar. (kgf / cm2), of any length. Hoses are made "for the client", i.е. with the parameters that you need, and with the fittings, the most suited for you. Each client receives from us a complete set of accompanying documentation: a passport, a table of chemical resistance, a manual for operating of metal hose made of stainless steel.
