Pipe Schedule Chart: How to Read Wall Thickness by NPS
The schedule number is not a thickness. This guide explains how pipe schedules work under ASME B36.10, with a wall-thickness table for common sizes and what to state on an RFQ.
Weld Neck vs Slip-On Flange: Which Joint Do You Need?
Hub, bore, welding and fatigue behaviour compared — and the services where a slip-on is perfectly acceptable.
Butt Weld vs Socket Weld Fittings
Two ways of joining small and large bore pipe, compared on strength, flow, inspection and cost — and where each one belongs.
Long Radius vs Short Radius Elbows
1.5D against 1D: what the radius changes for pressure drop, space and pigging, and how to specify the right one.
Flange Face Types: RF, FF, RTJ, Tongue & Groove
What the facing on a flange drawing means for gaskets, bolting and pressure — and why mating faces must match.
Seamless vs ERW Pipe: How to Choose
How the two pipes are made, where the weld seam matters, and how service, size and standard decide the choice.
