Wall thickness of reducer fittings
Thread Content
Reducer from 1/2" to 1/4", with wall thickness class Sch.160 – it’s not listed in ANSI B16.9. Could someone please tell me what the wall thickness is for 1/4"? Thank you
The GBT12459-2005 standard for steel butt-welded seamless pipe fittings specifies certain requirements and key dimensions regarding the sizes and tolerances of reducer pipes. To determine the wall thickness of a reducer, it is generally necessary to first decide on the wall thickness of the pipe based on parameters such as pressure, temperature, and material, and then determine the wall thickness of the reducer. Appendix Table B.1 at the end of GBT12459-2005 provides the wall thickness grades for seamless steel pipes used in connections with fittings. According to this table, the nominal wall thickness for SCH160, 1/2” is 4.78 mm; for SCH160, 1/4”, no value is listed in the table, but 3.02 mm can be used based on the XS reinforced pipe wall thickness series. For reference!
