Selecting pipe and piping materials - Specifying Engine

Sep 17, 2018· Selecting pipe and piping materials It also is a good choice for steam and steam-condensate systems because it handles high temperatures and pressures well, and corrosion is normally not an issue in steam pipes. However, corrosion is an issue in steam-condensate pipes, and many engineers specify schedule 80 steel pipe simply because it

Boiler Material - IB

Pipe and HRS plate are NOT the material to build a boiler, unless the pipe is something like oil well casing which has the same specification / inspection requirements as boiler tubing (I worked for an oil company for 10 years and know this from experience). You need to get certified material that is OK for Pressure Vessel application.

Making Sure Steam Piping Is Safe(10 Simple Rules a

Jun 28, 2005· The piping attached to the steam discharge flange must also be built to withstand the MAWP that the boiler can generate. In multiple boiler installations, the design rules typically apply to all piping through the second stop valve from the discharge flange of the boiler and are governed by ASME Code Section I and B31.1.
