One-Minute Overview

Stainless steel welded pipe, 38 mm outside diameter with a 2.0 mm wall.
Built to ASME B36.19M, the dimensional standard for stainless steel pipe.
Light wall welded tube for petroleum, chemical and food processing lines.
Precision welds delivering clean flow in a compact, easy to install format.

This stainless steel welded pipe is the compact end of industrial tubing: 38 mm outside diameter, 2.0 mm wall, made to ASME B36.19M. That standard is the dimensional reference for stainless steel pipe, fixing outside diameters and wall thickness series so fittings, valves and supports line up without rework. The grade is austenitic stainless — the corrosion resistant family behind most food, chemical and process lines — and the welded construction keeps the cost and weight down where a seamless tube would be overkill. It moves fluid cleanly in petroleum, chemical engineering and food processing service.

Name: Stainless Steel Welded Pipe
Type: Welded
Size: 38 mm
Material: Stainless Steel
Standard: ASME B36.19M
Wall Thickness: 2.0 mm
Application: Used for various industrial fields, such as petroleum, chemical engineering, food processing, etc.

How the pipe is welded decides how it behaves. Common routes for this size are high-frequency welding, TIG and laser welding: forming the strip into a tube, then joining the edges under controlled heat so the bead is narrow, sound and smooth enough not to restrict flow. At 2.0 mm wall the finished pipe is light, which simplifies supports and installation on racks and skids, while the stainless surface resists the rust and product contamination that carbon steel brings to wet lines. Keep the weld zone clean during installation, use stainless tooling, and passivate after welding where the service demands a pristine surface.

Ordering is about confirming the dimensional series against your drawing — outside diameter, wall and the schedule logic of B36.19M. Size and wall thickness are confirmed per inquiry, and a detailed specification sheet is available on request.

FAQ

Q1. Why does stainless pipe use its own dimensional standard?

ASME B36.19M exists because stainless wall series differ from carbon steel ones — the material behaves differently and the schedules reflect that. Using the right standard means a 38 mm pipe meets the fittings, valves and supports designed for it without surprises on site.

Q2. Which welding method is used on this pipe?

High-frequency welding, TIG and laser welding are all common at this size, chosen for the wall and the finish the order calls for. Whatever the route, the bead is kept narrow and sound, and the pipe is tested before dispatch so flow is not compromised.

Q3. Is welded stainless good enough for food processing?

Yes, with the right surface discipline. Austenitic stainless resists product contamination and cleans down well; the weld just needs to be sound and the surface passivated after fabrication. Tell us the product and we will confirm the finish with you.

Q4. What is the minimum order for stainless welded pipe?

Standard flange insulation gasket kits start at one set, and standard gaskets, studs, washers and sleeves start at one piece. Kits made to your drawing or for a non-standard bolt pattern are quoted individually, because the minimum really depends on the material and the tooling involved.
