OVERVIEW

Product Description

Our integrated manufacturing edge gives us the ability to produce steel in a variety of finishes, surface options and profiles

Composition limits for the grades in the tube and pipe programme are in the grade reference. Weight per metre from outside diameter and wall thickness is in the pipe and tube weight chart, and the weight calculator takes the same two numbers.

Phase 1 of the seamless programme covers outside diameters from 15.88 mm to 60.3 mm and wall thicknesses from 1.24 mm to 6 mm for straight-length heat-exchanger tubes. Boiler and line-pipe limits are listed separately in the table.

Which seamless pipe and tube grades are listed?

Published grades for seamless pipe and tube include 304L, 304H, 316L, 316H, 316Ti, 317L, 321, 321H, 347H and duplex grades, depending on the product route.

Which seamless tube and pipe specifications are covered?

The seamless programme references ASTM A213, ASTM A789, ASTM A269, ASTM A790, ASME SA213, ASME SA789, ASME SA312 and EN 10216-5. The applicable specification depends on whether the order is for heat-exchanger tube, boiler tube or line pipe.

How can stainless steel seamless pipe, tube and mother hollow be packed and traced?

Laxcon packs stainless steel seamless pipe, tube and mother hollow in standard bundles of 500 to 1,000 kg with HDPE or LDPE wrapping and two lifting slings. ISPM 15 wooden boxes and fibre-tube packing are available, and every bundle is marked with heat number, grade, size, and net and gross weight.

What should an RFQ for stainless steel seamless pipe, tube and mother hollow include?

An enquiry for stainless steel seamless pipe, tube and mother hollow is quotable when it states the grade, governing standard, metric size or profile, tolerance, finish or heat-treatment condition, length, quantity, test or inspection requirement, and delivery destination.
