Introduction: Performance test of metal hose metal hose is a key connecting component in engineering technology, which is composed of corrugated flexible pipe, mesh sleeve and joint. It is used as compensation element in various gas and infusion pipeline systems and their length, temperature, position and angle compensation systems

Metal hose Metal hose is a key connecting component in engineering technology, which is composed of corrugated flexible pipe, net sleeve and joint.
It is used as compensation element, sealing element, connecting element and damping element in various gas transmission and infusion pipeline systems and their length, temperature, position and angle compensation systems, and is applied in aerospace, petrochemical, mining electronics, mechanical shipbuilding, medical and health, light textile electronics, energy construction and other fields.
The recent specification of metal hose is "general specification for corrugated metal hose" (GB / t14525-2010). Because the application field of metal hose is very wide, it is necessary to conduct necessary inspection or test for metal hose in different places of use to confirm the reliability of its design. Soft connection
In order to meet the use requirements, the metal hose should be tested, such as basic test, special test, typical test and evaluation test. They include strength, air tightness, impact, pulsation, vibration, swing, friction resistance, temperature, corrosion resistance, bending fatigue and blasting.
Naturally, it is not necessary to carry out a return test on all metal hoses. According to the different requirements of metal hose, different test contents and test methods should be selected. Block one section of the metal hose and fill the other end with liquid for pressurization.
According to different requirements, water, potassium dichromate solution, 20 machine oil or red oil can be used as test media. Keep the pressure for 10 minutes under the pressure of 1.3-1.5 times without leakage. In case of small size and large-scale production, it is allowed to test multiple pipes in series, and the total length is determined according to the test equipment conditions.
The metal hose shall not be stored for more than two days and nights after the inspection, delivery and test. In order to ensure the integrity of the hose and preservation materials during transportation, the hose must be pre tightened with special cushion block, belt, rubber gasket, plastic and corrugated cardboard in the packing box.
It is a production-oriented enterprise integrating R & D, production and sales of valve and pipe fittings. It has more than ten years of experience in designing pipeline products and strong manufacturing capacity of pipeline supporting equipment Telescopic device Pipeline compensation joint, flue gas, air and pulverized coal pipeline Compensator (expansion joint), steam and water pipeline compensator (expansion joint), and Rubber joint Corrugated compensator (expansion joint), metal hose, steel gate, damper, gate and other products. Enterprises choose sand removal, welding, painting process, so that its products are durable, smooth and clean appearance. It is widely used in petroleum, chemical industry, natural gas, electric power, heating, pharmaceutical, metallurgy, municipal and other industries, and is sold to more than ten countries and regions in the Middle East, Europe and the United States. Win the general praise, trust and application of customers.
