What is the technology behind seamless SS pipes
- Cold rolling is the preferred production process for high-precision seamless stainless steel tubes.Most of our heat exchanger tubes and precision tubes are manufactured using cold rolling.This process offers advantages such as high forming efficiency,tight tolerances,and excellent yield rates.Currently,the maximum tube diameter achievable with this process is 114.3 millimeters.
- Cold drawing is the standard processing method for our stainless steel tubing.Cold-drawn stainless steel tubing achieves extremely tight tolerances while maintaining excellent chemical composition. Furthermore,when surface microstructure quality demands are exceptionally high,cold drawing proves the ideal choice.

FAQ
how to order?
When you want to get a quote or place an order to us, pls clear the information:
Product + Dimension + Material + Order Quantity
For example, you want to buy 100 meters 316L stainless steel pipe, Seamless, quality to ASTM A312, 6″ SCH40S, beveled end, so the description would be:
SMLS, ASTM A312 TP316L, 6″ SCH40S, BE, 100 Meters
For the pipe quality, we will think it is ASME as they are the common grade in the market.
