About factory

1.NEW SINDA STEEL PIPE CO.,LTD.is one of the biggest manufacturer about the steel pipe from china.

2.We have got two complete production line as:

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

  -, Hot rolled from size 6"-16" OD pipe, also we can work from size 20"-24" as hot expand pipe.

 3. We have got carbon steel pipe for liquid use (ASTM A106/A53GR.B),steel pipe for casing (P-110, K55, N80 and so), steel pipe for pipeline (API5L GR.B, X42, X52, 60, X70), steel pipe for construction (high thickness of ST45, ST52).

Looking forward for a long-term and win-win coorperation.
