Orbital Welding Stainless Steel Tube: Purging, Fit-Up and Inspection Guide

Quick answer: Reliable orbital welding of stainless steel tube depends on more than the welding program. Tube chemistry, end preparation, joint fit-up, shielding and internal purge control, heat input, cleanliness and inspection acceptance must work together. Orbital GTAW improves repeatability,...

Stainless Steel PMI Testing: What XRF Can Verify—and What It Cannot

PMI helps detect alloy mix-ups, but a handheld analyzer reading is not a complete acceptance certificate. For stainless steel bar, plate and pipe purchases, the important question is not simply whether PMI is available. It is whether the selected method can measure the elements that distinguish ...

How to Specify Stainless Steel Pipe for Pressure Service: Grade, Dimensions and Inspection

For pressure-service stainless steel pipe, grade alone is not a complete specification. A usable purchase requirement must connect the material grade, pipe standard, manufacturing route, outside diameter, wall thickness or schedule, end preparation, testing scope and service conditions. Missi... Read More

Stainless Steel Pipe End Preparation: Plain, Beveled and Threaded Ends

The correct pipe end is determined by the joint design—not by stainless steel grade alone. A plain end leaves the pipe ready for cutting or project-specific preparation; a beveled end prepares the pipe for a butt-welded joint; and a threaded end is used only where the piping specification, wall ...

Beyond 0.02 mm: How SAKYSTEEL Supports Ultra-Thin Stainless Steel Strip Projects

When stainless steel is discussed, attention often goes first to large coils, wide plate and annual tonnage. But narrow the material from conventional sheet to precision strip, reduce the gauge from tenths of a millimetre toward 0.02 mm, and the rules begin to change. At that point, the questio...

Why 0.02 mm Stainless Steel Precision Strip Is More Than a Thickness Target

The difficult part of ultra-thin stainless steel strip is not reaching a nominal gauge such as 0.02 mm. It is delivering a stable material condition across the full coil and from one batch to the next. For stamping, springs, medical tubing, electronic components and other precision applications,...
