Technical characteristics

Metal hose is sealed in the shell — annular corrugation stainless steel enclosed in a protective sheath, of one, two or three layers. End fittings butt weld is designed to connect pipeline systems. The purpose is the reduction of installation, vibration, thermal and other stresses, which are inevitable when transporting liquid and gaseous products with varying parameters of temperature and speed and pressure.

Manufacturer

Metal hose for welding is made of stainless steel 12X18H10T and its foreign counterparts with the thickness of the steel tape of 0.15 mm to 0.5 mm. used For braiding steel with the brand 12x18h9t. Flexible part is made of stainless billets with a mechanical or hydraulic forming of corrugations. The product with the brand SRGS is produced by convolution of the spiral steel tape, pre-profiled. Contact seam welding is performed on top of the corrugation.

Metallorukav has a standard diameter of 20 mm to 350 mm with length of flexible part from 250 mm to 6000 mm. Marking of products (for example, 4655А-2−80−30−4,0) is performed according to the accepted standard:

· 4655А — series metal hose,

· 2 — compliance with conditions (ground conditions),

· 80 — DN — nominal diameter,

· 30 — 30 kg/sq cm working pressure,

· 4,0 — length L — 4 meters.

The use

Distinguish metallorukav land, air and sea applications. Provide transportation of various gases and liquids at temperatures from -270 to +650°C, With a pressure range from vacuum up to 300 Bar. Widely used in petroleum, gas industry, machine tool industry, automotive industry, aircraft industry, shipbuilding and construction.

Dignity

Such flexible connection fire resistant, reliability, durability. The main power element of construction is a metal braid, which takes the radial and axial power load, preventing the bending of the sleeve. This allows you to compensate for temperature, geometric displacement, reduces noise, dampens vibration between the fixed and vibrating parts of machinery and pipelines.

Choice

Consider the planned operating conditions. Use is limited to pipe sections with a speed of 8.0 m/s for liquids and 50.0 m/s for gases. They determined the optimal length for each individual case, is not allowed twisting, compression or tension of the product. You need to provide a neutral plots in the areas of end fittings, which are not exposed to bending during operation of the equipment.

Installation

The installation is subject to the availability of small for the length of the loose sections. To prevent excessive sagging as the supports used hose clamps, trays, coasters with strips of leather, rubber or PTFE. The distance between supports should be no more than two metres are not allowed to move and the friction of the sleeve with respect to the supports.
