Introduction about Grade of Casing&Tubing
There are 20 different steel grades and types of oil casing and tubing in H40, J55, K55, M65, N80, L80, C90, T95, C95, P110, Q125
The difference and advantage of ERW pipe and seamless pipe
Due to the advanced production technology and high production efficiency, the production cost of ERW steel pipe is much lower than that of seamless steel pipe, and the price is also more advantageous.
Comparison of ERW steel pipe and SSAW steel pipe
Compared with SSAW, there is little difference in price between ERW steel pipe and SSAW steel pipe. The length of SSAW weld joint is about 2~3 times of ERW weld joint, and its internal weld tumor has no technical ability to remove
How to choose suitable steel pipe which used in pressure pipeline ?
First of all, it is necessary to understand the type, specification, performance and scope of use of the pipe. It is better to investigate the application of the pipe in other similar pressure pipes, and then determine the material of the pipe according to the following principles.
Advantages of anti-corrosion spiral steel pipe
Good heat preservation effect: 3PE anti-corrosion spiral steel pipe has good heat preservation performance, and the heat loss is only 25% of that of traditional pipes. Long-term operation can still save relatively large resources and significantly reduce energy costs.
Difference between hot-dipped galvanized steel pipe and cold galvanized steel pipe
old galvanized pipe and hot-dippedgalvanized pipe has a great difference in the operation mode. The zinc in hot-dippedgalvanizing is obtained at 450 degrees Celsius to 480 degrees Celsius, while the zinc in cold-galvanized steel pipe is obtained by electroplating at room temperature.
Difference between carbon steel pipe and stainless steel pipe
Stainless steel pipe can be divided into equal section pipe and variable section pipe according to the shape of the vertical section. Variable section tube has conical tube, step tube, periodic section tube and so on.
