ASTM A106 Seamless carbon steel tube for high temperature service

ASTM A106 / A106M - 11 Standard Specification for Seamless Carbon Steel Pipe for High-Temperature Service

Description:

1.standards: ASTM A106 (ASME SA106)

2.products mainly used: apply to bending, curling and similar forming process.

3.the main products of steel / steel grade: Gr.A; Gr.B; Gr.C.

4.Specifications: diameter: 10.3 to 114.3 mm thickness: 0.8 to 12 mm Length: 6 m above, and, in accordance with customer demand, supply and other specifications of steel pipe.

5.Chemical composition and mechanical properties

6.JIS Number and Corrensponding Foreign Standards

Scope:1. This specification covers seamless carbon steel pipe for high-temperature service (Note 1) in NPS 1/8 to NPS 48 inclusive, with nominal (average) wall thickness as given is ANSI B36.10. Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of this specification. Pipe ordered under this specification shall be suitable for bending, flanging, and similar forming operations, and for welding. When the steel is to be welded, it is presupposed that a welding procedure suitable to the grade of steel and intended use or service will be utilized (Note 2).

NOTE 1 Α Consideration should be given to possible graphitization of the material at the higer temperatures at which it may be used.

NOTE 2 Α Grades A rather than Grades B or Grades C pipe should be used for close coiling, or cold bending. The purpose for which the pipe is to be used should be stated in the order. This note is not intended to prohibit the cold bending of Grades B seamless pipe.

2. Supplementary requirements (S1 to S4) of an optional nature are provided for seamless pipe intended for use in applications where a superior grade of pipe is required. These supplementary requirements call for additional tests to be made and when desired shall be so stated in the order.

3. When these products are to be used in applications conforming to ISO Recommendations for Boiler Construction, the requirements of Specification A 520 (Mechanical Property Requirements Section) shall supplement and supersede the requirements of this specification. 1.4 The values stated in inch-pound units are to be regarded as the standard.

NOTE 3 Α The dimensionless designator NPS (nominal pipe size) has been substituted in this standard for such traditional terms as "nominal diameter", "size", and "nominal size".

5. The following precautionary caveat pertains only to the test method portion, Sections 11, 12, 13, 14, and 15, of this specification; This standard does not purport to address all of the safety problem, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
