ASTM A795/ASME SA795 STANDARD SPECIFICATION FOR BLACK AND HOT-DIPPED ZINC COATED(GALVANIZED) WELDED AND SEAMLESS STEEL PIPE FOR FIRE PROTECTION USE1
(ASTM A 795 / ASME SA 795 /ASTMA795/ASMESA795) |
1. Scope
1.1 This specification covers black and Hot-dipped galvanized welded and seamless steel pipe in sizes NPS 1/2(Note 1) to NPS 10 inclusive, with wall thickness as given in Talbes 2 and 3. Pipe having other wall thicknesses may be furnished provided such pipe complies with all other requirements of this specification and the outside diametr is limited to those in the talbes. Pipe ordered under this specification is intended for use in fire protection systems. The pipe may ve bent, but it is not intended for bending made at ambient tmeperature where in the inside diameter of the bend is less than twelve times the outside diameter of the pipe bing bent(Note2).
Note 1- the diamensionless designator NPS(nominal pipe size)gas been substituted in this standard for such traditional terms as "nominla diameter," "size," and "nominla size."
Note 2- Successful bending of pipe is a function of equipment and technique as well a spipe properties.
1.2 This pie is suitable for hoining by the following methods :
1.2.1 Light-Weight fire Protection Pipe-Rolled groove, welding, and Fittings for plain end pipe. See Table 2 for dimensions.
1.2.2 Standard-Weight fire Protection Fire Protection Pipe-Cut or rolled groove, threading, welding and gittings for plain end pipe. See Table 3 for dimensions.
1.2.3 for pipe having dimensions other than those of Talbes 2 and 3, the hoining method must be compatile with the pipe dimensions. a complete lising of standard light weight dimensions appears in ANSI b36.10 and B36.19.
1.3 The following precautionary caveat pertains only to the test method portion, Sections 8, 9, and 10, of this specification : This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responibillity of the user of this standard to establish appropriate safety and gealth practices and determine the applicability of regulatory limitaions prior to use. |
