Description

Ronsco produces welded stainless steel pipe & tube in different shapes: round, square and rectangle. In comparison with seamless pipe, the lead time for stainless steel welded time is way shorter. For common welded pipes, whether common in grades (304, 304L, 316, 316L ) or common in dimensions (SCH5S, SCH10S, SCH40, SCH80), we have huge stocks for your choices. It can take a week for port delivery. Other grades than the above mentioned such as 304H, 316H, 316Ti, 309S, 310S, 317L, 347, 321, duplex and nickel alloy, it can take longer time roughly two to three weeks to finish production.


Have to mention, the above mentioned lead time is estimated as per our manufacturing experience. For accurate feedback, we encourage your confirmation with us to avoid discrepancy. In terms of quality control, our welded pipes are subjected to X-ray inspection, Hrdro inspection, PMI inspection and others upon your request. The production capacity of stainless steel welded pipe amounts to 1200 tons monthly.
