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…
A spectacle blind is a key component of pipeline systems that provides isolation of certain sections as the need arises. Typically, the entire device consists of a blind and a…
Stub-in pipe refers to a branch connection between a pipe and a header. Making this connection involves drilling a hole into the header of the run pipe and fitting the…
The SDR pipe stands for “Standard Dimensional Ratio” and describes the pipe’s geometry. The nominal outer diameter to nominal wall thickness ratio is known as the SDR. This article defines…
SDR-26 and Schedule 40 pipe offer varying levels of wall thicknesses for piping frameworks. Both Schedule and SDR pipes have external diameters based on IPS (iron pipe standard), yet their…
The trap guard provides a novel, trapless way of sealing sewer gas from returning through a drain. It competes as an alternative or potential supplement to p-traps. In this article,…
Venturi and orifice meters are devices that reduce the pressure of a moving stream to measure its average velocity, volumetric flow rate, or mass flow rate. The continuity equation and…
