The complex chemical and physical properties of the various grades of Carbon steel seamless pipes allow for a broad range of service usage. Bellowman has the right grade (including ASTM A 106 Gr. A、B & C , ASTM A53 Gr. A、B & C and API 5L X-42 thru X-80 ), size and price to meet your requirements . ASTM A 106 Gr. Gr. A、B & C are utilized for services ranging from structural supports to steam drum headers with temperatrue ranges up to 450℃ while API 5L X-42 thru X-80 are for conveying gas,water and oil in both the oil and natural gas industries.

 

According to the practice and application, the Carbon steel seamless pipes can be divided into ASTM A 106 / A53 seamless pipes、seamless line pipes、seamless casing and tubing、seamless drill pipes、high pressure boiler pipe and mechanical structural pipes. And according to different manufacturing methods, the Carbon steel seamless pipes can be divided into Hot rolled seamless pipes、cold rolled seamless pipes and cold drawn seamless pipes. Cold rolled has better dimensional accuracy than hot working.
