ASTM A Seamless Pipe, ASTM A Welded Pipe, ASTM AM Duplex Pipes.
Extended elevated temperature exposure can embrittle stainless. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Tensile and Hardness Requirements.
It is highly suitable for usage in marine environments. These pipes may be repaired per Sections 12 and Link to Active This link will always route to the current Active version of the standard. Work Item s – proposed revisions a90 this standard. These supplementary requirements call for additional tests to be made and, when desired, one or more of these may be specified in the order.
Workmanship, Finish, and Appearance Appendix X1 of this specification lists the dimensions of welded and stainless steel seamless pipe as shown a7990 ANSI B The dimensionless designator Nominal Pipe Size nominal pipe size has been substituted in this standard for such traditional terms as nominal diameter, size, and nominal size.
Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of this specication. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
Pipe shall be welded in one pass awtm processes employing filler metal and shall be completely radiographed. Our products go through appropriate testing, both in Government and private laboratories.
If a specimen from any length of pipe fails because of a lack of soundness that length shall be rejected, unless subsequent retesting indicates that the remaining length is sound. On specied asgm up to 0.
ASTM A790 Seamless and Welded Pipe
NOTE 2—This value applies when the inch-pound designation of this specication is the basis of purchase. A steel pipes piping. The inch-pound units shall apply unless the M designation of this specification is specified in the order. Pipe shall be double welded by processes employing filler metal in all passes and shall be spot radiographed.
Duplex Steel Products: Combining values from the two systems may result ast, nonconformance with the specication. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. The inch-pound units shall apply unless the M designation of this specification is specified in the order. Mega Mex supplies LDX,FerraliumZeron and in the form of plate, sheetstrip, bar, pipe, tubing, pipe fittings, flanges and weld wire.

Home Contact Us Back to Top. The pipe shall be made by the seamless or an automatic welding process, with no addition aatm filler metal in the welding operation.
Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of this specification. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
If this supplementary requirement is specied, the number of tests per pipe required shall also be specied. ASME SA Ferritic Stainless Steel Welded Pipes has a higher yield strength and lower ductility than the austenitic steels so fabricators may find that higher forming forces, increased radius of bending, and increased allowance for spring back are necessary.
