Application range of high frequency vertical ERW steel pipe
In both low and high pressure environment, we should obtain the legal steel pipe from seamless steel tube, ERW steel pipe and SSAW steel pipe for long-term life service.Under this situation, we should figure out the characters and main application environment for different steel pipes. Today, we would have an introduction for application range for high frequency longitudinal ERW steel pipe. 1. Oil, natural gas convey: Municipal gas transmission, long distance transportation of oil and natural gas would under the help of high frequency longitudinal ERW steel pipe. 2. Casing and tubing: This is another area we can count on ERW steel pipe. There is only seamless steel pipe can hold on this duty. However, with the high technology's development, now we can use ERW steel pipe to replace it. 3. Constructional structural pipes: No matter round, square or rectangular, we can use ERW steel pipe for frameworks of super malls, theater, airports, bridges and so on. ...
Testing explanation for steel pipe
In order to give customers secure steel products, such as seamless steel pipe, ERW steel pipe and so on, Tianjin Xinyue Steel Group would do various tests before the finally step of selling. Our steel pipes’ tests covers from Chemical Component Analysis, Mechanical Properties (Ultimate tensile strength, Yield strength, Elongation), Technical Properties (Flattening Test, Bending Test, Blow Test, Impact Test), Exterior Size Inspection, Hydrostatic Test to X-ray Test. Today, we would like to have a details introduction to Hydrostatic Pressure Testing. Hydrostatic Pressure Testing: Hydrostatic test is a test which coming after the pressure vessel is manufactured. Manufacturers would add appropriate amount of water to the vessel in order to test the macroscopic strength of the vessel (if it is deformed too much) and the sealing point and welding before the newly installed vessel 3 is used or entered.
