Scope1.1 This specification covers electric fusion welded pipesuitable for high-temperature or corrosive service as listed
3、 inTable 1. (Although no restrictions are placed on the sizes ofpipe that may be furnished under this specification, commercialpractice is commonly limited to sizes not less than 8 in. (203mm) nominal diameter.)1.2 Five classes of pipe are covered as follows:1.2.1 Class 1Pipe shall be double welded
4、by processesemploying filler metal in all passes and shall be completelyradiographed.1.2.2 Class 2Pipe shall be double welded by processesemploying filler metal in all passes. No radiography is re-quired.1.2.3 Class 3Pipe shall be single welded by processesemploying filler metal in all passes and sh
5、all be completelyradiographed.1.2.4 Class 4Same as Class 3 except that the weld passexposed to the inside pipe surface may be made without theaddition of filler metal.1.2.5 Class 5Pipe shall be double welded by processesemploying filler metal in all passes and shall be spot radio-graphed.1.3 The val
6、ues stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with
7、 its use. It is theresponsibility of the user of this standard to become familiarwith all hazards including those identified in the appropriateMaterial Safety Data Sheet (MSDS) for this product/materialas provided by the manufacturer, to establish appropriatesafety and health practices, and determin
