Butt Weld vs Socket Weld
During the construction of various structures, there are different methods of interfacing pipe flanges, fittings, and other connecting parts. Out of these methods, using a butt weld or socket weld…

A restrained joint pipe serves to prevent separation of joints on a pressurized pipeline due to thrust forces. Generally, in a straight pipe section, hydrostatic forces balance themselves out. Whenever…
Both Hazen-Williams and Darcy-Weisbach equations compute head loss due to friction in a pipe. Hazen-Williams coefficient is a function of only the pipe roughness vs Darcy-Weisbach which considers internal roughness,…
A 3-inch sewer pipe slope should be between 3/16″ and 5/16″ per foot. In this article, we will review how to determine the slope of a 3″ sewer pipe, a…
The SDR rating scheme for the pipe includes SDR 11 and SDR 17. At a 100°F operating temperature, SDR 11 provides a pressure rating of 126psi vs SDR 17, which…
SDR 21 and SDR 26 are both under the SDR rating system for the pipe. SDR 21 has a 200 psi rating, vs SDR 26 which has a 160 psi…
Pipe obvert elevation is the vertical distance between the inside-top of a pipe and any datum. Moreover, the term ‘obvert’ means to turn. The obvert measurement mirrors the pipe invert,…
SDR 11 vs. SDR 13.5 both categorize under the SDR rating system for the pipe. The SDR (standard dimension ratio) is a pressure pipe rating method. The SDR increases as…
NPT and NPTF are standard thread designs that enjoy wide levels of adoption in industry. For pipes, the NPT threading requirements should be as per ANSI B1.20.1, while NPTF requirements…
SDR 26 and SDR 35 both categorize under the SDR rating system for pipe. At 5% deflection, the SDR 26 pipe can undergo pressurization of 115psi vs the SDR 35…
