Seamless pipe has no longitudinal weld, so there is no heat-affected zone running the length of the line and no weld defect to find later. It is the base product behind most of what we supply: cut, bevelled, tested and certified to the project specification.
Outside diameter 4–900 mm, wall thickness by schedule or by drawing; round and shaped sections (square, oval, hexagonal, finned) on request.
Hot-rolled for heavy wall and large diameter, cold-drawn for thin wall and tight tolerance.
Uniform stress distribution and 20–30% higher pressure capability at equal wall thickness.
Outside diameter tolerance ±0.2% and wall tolerance within 5% on cold-drawn product.
Cold-rolled / cold-drawn precision tube, mirror bore, tight wall tolerance.
Specifications
Small-bore precision tubing for impulse, sampling and signal lines.
Specifications
Hygienic stainless tube, Ra ≤ 0.8 µm bore, CIP/SIP compatible.
