Seamless (SMLS) pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. Seamless Steel Pipe withstands pressure better than other types of pipe, which is why it is the favorable choice for oil and gas transportation.

The complex chemical and physical properties of the various grades of carbon steel pipe allow for a broad range of service usage. HYSP QCCO China Steel has the right grade, size and price to meet your requirements including ASTM/ASME A/SA-106 Grade B/C and API 5L X- 42 thru X -70.

ASTM/ASME A/SA-106 Grades B & C are utilized for services ranging from structural supports to steam drum headers with temperature ranges up to 800 Fahrenheit while API 5L X Grades 42 thru 70 are utilized for the water and petroleum industry to transport liquids or as platforms on off shore rigs.
