2、theses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This specification2covers welded UNS N08020 alloypipe for general corrosion-resisting and low-or high-temperature service.1.2 The pipe covered is nomina
3、l pipe sizes up to andincluding NPS 6 168 mm with the nominal wall thicknessesgiven as Schedules 5S,10S,and 40S and nominal pipe sizes upto and including NPS 2 60 mm also including Schedule 80S.Table 2 of Specification B775 is based on Table A1 of ANSIB36.19 and gives the nominal dimensions of these
4、 sizes.Table 3 of Specification B775 lists the dimensional require-ments of these sizes.Pipe having other dimensions may befurnished provided such pipe complies with all other require-ments of this specification.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separatel
