Seamless Steel Pipe(SMLS) is made from a solid round steel billet which is heated and pushed or pulled over a form until the steel is shaped into a hollow tube. The seamless pipe is then finished to dimensional and wall thickness specifications in sizes from 1/8'' to 36'' OD.

1.Cold drawn from size 3/4"-5"  OD pipe.

2.Hot rolled from size 1"-16" OD pipe, also we can work from size 20"-24" as hot expand pipe. 

3.Wall thickness can be max 100mm now.

4.One new productionline for seamless Rectangular steel pipe

5.Certificates: API   ISO  &  KR
