Application range for high frequency longitudinal ERW steel pipe

Whether low pressure or high pressure environment, we should take the rightful steel pipe from seamless steel pipe, ERW steel pipe, SSAW steel pipe for the long 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.

4. Low pressure flow products' transmission: water would be an important one.
