Seamless stainless steel pipe is processed from round steel ingots via piercing, rolling, drawing and extrusion procedures. It features fully smooth inner and outer surfaces without any straight weld seam. When placing an order, the customer usually specifies material grade, outer diameter, wall thickness, pipe length and surface treatment requirement. For pressure pipeline application, its tensile strength reaches 490-650 MPa. Large-sized thick wall pipe adopts hot rolling production, while cold drawing process is applied for product requiring high dimensional accuracy.

Product Advantages
The weld-free body removes one common weak point in pressure lines.
Cold drawing can be used when the buyer needs tighter dimensions.
The smooth inner wall of seamless stainless steel pipe helps reduce flow resistance.
Material and end treatment can be selected for different equipment connections.
Why choose us
Many orders are delayed by unclear grade names or tolerance requirements. We ask for these details at the quotation stage and keep the inspection papers tied to the shipment batch.
We help buyers check grade, pipe schedule, outside diameter, wall thickness and surface request. Third-party inspection and test reports can be prepared when the contract asks for them.
FAQ
Q: What is the main difference from welded pipe?
A: The pipe body has no longitudinal welded joint.
Q: Which processes are available?
A: Hot rolling, cold rolling, cold drawing and extrusion are listed in the supplied document.
Q: Can stainless steel grade be customized?
A: Yes. Grade and size should be confirmed before production.
Q: What should be checked before ordering this seamless stainless steel pipe?
A: Material, size range, wall thickness, surface treatment, test request and delivery length should be checked before production.
