Selection of a metal hose according to the characteristics of the bellows

Bitumen metal hoses are constructed on the basis of stainless bellows. This ensures product reliability, tightness, durability and flexibility. The execution of the bellows in standard and atypical (taking into account the requirements of the customer) execution allows you to choose the desired type of product for any parameters.

For qualified assistance in the selection of metal hoses, send applications indicating the main characteristics (bending radius, working pressure, temperature, etc.) to the employees of VZM JSC

Advantages of ordering bypass metal hoses manufactured by JSC "VZM"

• The thermally insulating medium in the external circuit of the bitumen sleeve maintains a constant temperature of the working medium in the internal circuit without heat loss.
• The metal hose works in conditions of high and low temperatures from -196 ° С to + 600 ° С.
• Let's warm the metal hose to the desired temperature without violating the tightness.
• Possibility of use in especially critical sections of pipelines and areas with hazardous environments in signal systems: a change in pressure in the external circuit indicates a violation of the integrity of the internal circuit.

Price of bitumen metal hose

The price of a metal hose depends on the diameter, working pressure, length, type of end fittings and other parameters. Leave a request for processing by VZM JSC specialists and obtaining information about the price and delivery time.
