Overview

AD2000 W2 US Test Stainless Steel Tube is a long steel bar with a hollow cross-section and no peripheral joints. It is produced by cold-drawing or hot-rolling and has a polished surface, all according to customer requirements. It has thick walls and is available in various sizes and lengths. AD2000 W2 US Test Stainless Steel Tube is widely used in the petroleum, chemical, medical, food, light industry, mechanical and instrumentation industries.

AD2000 W2 US Test Stainless Steel Tube has the stability and resistance to acids and alkalis that ordinary welded steel tubes do not have, and is highly resistant to pressure. It is stronger than other metal materials and can resist impact. It is also resistant to abrasion, corrosion, rust and oxidation and has a long service life. Our steel pipes are affordable and cost effective, making them the perfect choice for you.

Parameter

Materials: 1.4301, 1.4306, 1.4401, 1.4404, 1.4833, 1.4845, 1.4571, 1.4438, 1.4541, 1.4550, 1.4539, 1.4362, 1.4462, 1.4410, 1.4501 and so on.

Similar Standards: EN10216-5, ASTM A213, ASME SA213, ASTM B163, ASME SB163, JIS G3463, DIN17458

Specification: OD 6.35mm to 508mm; WT 0.6mm to 30mm; Length Max 25m.

It can be applied to satisfy the basic safety requirements of the Pressure Equipment Directive, principally for the conformity assessment according to modules G and B+F.

It is structured along the lines of a self-contained concept. If other technical rules are used according to the state of the art to solve related problems, it is assumed that the overall concept has been taken into account.

It can be used as appropriate for other modules of the Pressure Equipment Directive or for different sectors of the law. Responsibility for testing is as specified in the provisions of the relevant sector of the law.

The AD 2000 Code W2 applies to seamless and welded tubes made of austenitic and austenitic-ferritic steels for the construction of pressure vessels operated at working temperatures and ambient temperatures down to -10 ℃ and up to the upper-temperature limits specified in clause 2. In principle, the steels are also suitable for use at temperatures lower than -10 ℃. For working temperatures below -10℃, AD2000-Merkblatt W10 is also applicable.

The basic requirements for the materials and material manufacturer are specified in AD 2000-Merkblatt W0.

For seamless tubes, the tests are carried out according to DIN EN 10216-5, test category 2.

Exception: for tubes with an outside diameter ≤42.4mm and nominal wall thickness ≤3.6mm and for internal tubes, the mechanical-technological tests of test category 1 are carried out.

In addition, the following tests shall be carried out:

1. Impact test

2. Resistance to intergranular corrosion

3. Non-destructive tests

For tubes within a pressure vessel (internal tubes), the ultrasonic examination may be dispensed with. This is generally the case also if the pressure in the tubes is greater than that in the pressure vessel. The order shall specify whether internal tubes are involved.

The products shall be marked clearly and permanently according to applicable standards.
