Minimum allowable wall thickness pipe
WebWhen steel pipe referenced in Table 6.3.1.1 is joined by threaded fittings referenced in 6.5.1 or by fittings used with pipe having cut grooves, the minimum wall thickness shall be in accordance with Schedule 30 pipe [in sizes 8 in. (200 mm) and larger] or Schedule 40 pipe [in sizes less than 8 in. (200 mm)] for pressures up to 300 psi (20.7 bar). Web= specified minimum wall thickness . Each DI pipe has a significant range of wall thickness (t) values within each pipe. This is a direct result of the casting process. To achieve the specified minimum wall thicknesses in DI pipe, much of the pipe is at thicknesses significantly above the minimum. In TN 3 Issue 1, 2005, it was …
