Overview

EN10216-5 TC2 CFA Stainless Steel Tube is made from ingots or solid billets that are perforated to form a blank tube and then hot rolled, cold rolled or cold drawn. It has high production efficiency, a wide range of specifications, low investment in equipment and high strength. EN10216-5 TC2 CFA Stainless Steel Tube is widely used in the manufacture of structural and mechanical components such as oil drilling rods, automotive drive shafts, bicycle frames and steel scaffolding for building construction.

As our technology advances, the quality of our EN10216-5 TC2 CFA Stainless Steel Tube continues to improve. Its surface is specially treated to form a film that makes the tube itself less susceptible to oxidation. It is also less susceptible to corrosion and rust. It has a smooth inner wall and low flow resistance, which ensures the normal flow of the medium inside the tube. Our products are stable, not easily deformed and can be used for a long time.

Rest difference between TC1 and TC2 (The main part is in EN10216-5 TC1 CFD stainless steel tube)

CFA tube means Cold finished bright annealed Metallically bright tubes.

All CFA tubes should be bright annealed. Solution annealed and picked conditions cannot be accepted.

NDT test

All NDT activities shall be carried out by qualified and competent level 1, 2 and/or 3 personnel

authorized to operate by the employer. The qualification shall be in accordance with ISO 11484 or, at least, an equivalent to it. It is recommended that the level 3 personnel be certified in accordance to EN ISO 9712 or, at least an equivalent to it. The operating authorization issued by the employer shall be in accordance with a written procedure.NDT operations shall be authorized by a level 3 NDT individual approved by the employer.

Process

The tubes shall be manufactured by a seamless process and maybe hot finished or cold finished.

The terms " hot finished " and " cold finished " apply to the condition of the tube before it is heat-treated in accordance with 7.2.3

Solution annealing

Solution annealed conditions obtained directly by extrusion and subsequent cooling provided the

mechanical properties, corrosion resistance and other properties are in accordance with this part of EN 10216. All specified mechanical properties shall be met even after a subsequent reference heat treatment (solution annealing).

Solution treatment shall consist of heating the tubes uniformly to a temperature within the range given for the steel grade concerned in Tables 6, 7, and 8 and cooling rapidly.

Materials (part)

Appearance

The tubes shall be free from external and internal surface defects that can be detected by visual examination.

The internal and external surface finish of the tubes shall be typical of the manufacturing process and, where applicable, the heat treatment employed. Normally the finish and surface condition shall be such that any surface imperfections requiring dressing can be identified.

It shall be permissible to dress, only by grinding or machining, surface imperfections provided that, after doing so, the wall thickness in the dressed area is not less than the specified minimum wall thickness. All dressed areas shall blend smoothly into the contour of the tube.

Surface imperfections that encroach on the specified minimum wall thickness shall be considered defects and tubes containing these shall be deemed not to conform to this part of EN 10216.

Leak-tightness

The tubes shall pass a hydrostatic test, an eddy current test or an ultrasonic test for leak-tightness. Unless it is specified, the choice of the test method is at the discretion of the manufacturer.

Non-destructive testing

The tubes of test category 2 with outside diameter greater than 101,6 mm or wall thickness greater than 5,6 mm shall be submitted to a non-destructive testing for the detection of longitudinal imperfections, according to 11.9.1.

Option 14: The tubes of test category 2 with specified outside diameter less than or equal to 101,6 mm and specified wall thickness less than or equal to 5,6 mm shall be submitted to a non-destructive testing for the detection of longitudinal imperfections according to 11.9.1.

Option 15: The tubes of test category 2 shall be submitted to a non-destructive testing for the detection of transverse imperfections according to 11.9.2.

Option 16: The tubes of test category 2 with specified wall thickness greater than 40 mm shall be submitted to a non-destructive testing for the detection of the laminar imperfections at the tube ends according to 11.9.3.

Straightness

The deviation from straightness of any tube length L shall not exceed 0,001 5 L. Deviations from straightness over any one meter length shall not exceed 3 mm.
