Description

lloy Steel Pipe SA **5 **5

In the process heating like boiler/ chemical industries / paper, if the temperature exceeds **0 Deg c and with in **0 Deg c. then boiler quality alloy steel can be efficiently used for headers, risers, main steam lines etc. ASME specifies a set of Alloy Steel pipe specifications Which can be welded - Welding rod Specification is : E.***8.

It can be effectively used for pipe welding. root run can be tig welded using alloy steel tig wire Standard pipe schedules are available like sch *0 , sch *0 etc - *0.3 mm O.D x 3.*3 mm thk pipe outer diameter and schedule is used in general practice. Such pipes have a negative tolerance which will be considered at the stage of designing [negative tolerance means variation in thickness up to a maximum of *2.5% to be checked from ASME SEC viii DIV*1] outer diameter ranges from *5 mm to **0 mm & thickness range from 2.*3 mm to *5 mm

The Alloy Steel Pipe Specifications as per [ ASME SEC viii DIV*1 ] are

SA **5 P*1
SA **5 P*2
SA **5 P*2
SA **5 P 5
SA **5 P 9
