Fatigue life is set by stress amplitude, mean stress, environment, and material strength - not by the schedule number. At comparable cyclic stress, nickel alloys such as Inconel 625 can outlast 304 stainless by an order of magnitude because they are stronger and far more corrosion-resistant. Always verify the final choice against ASME fatigue rules.

Schedule 80 is the same pipe as Schedule 40 with a ~40% thicker wall — stronger, heavier, and pricier, rated for roughly 40–44% more pressure — so Sch 40 handles general low-to-medium pressure duty while Sch 80 handles high pressure, threaded joints, and heavy service.

​Tube steel distortion is one of the most common and frustrating problem. Even slight warping, bending, or twisting—such deformations will affect your usage. The good news is that Tube Steel deformation can be addressed and prevented. This article draws on decades of metal knowledge and processing experience to help you correct and prevent Tube Steel deformation.


 

ASME B36.10 is the standard that defines the outside diameter and wall thickness of welded and seamless wrought steel pipe. A pipe schedule chart is the lookup table that turns a nominal pipe size (NPS) and a schedule number into the actual wall thickness, outside diameter, and weight of the pipe.

JN ALLOY project highlight - 30 tonnes of Incoloy 800 pipe delivered to a Kuwait petrochemical client in March 2026. Part of the Incoloy 800 product range.

This guide covers ASME B16.5 dimensions (Class 150/300/600), face and neck types, weight charts, and a selection table to help you specify the correct flange.

​Threaded flanges are pipe flanges that feature tapered internal thread. Their components include the flange blade containing the bolt holes and sealing face, the threaded bore that receives the pipe, and the hub that provides reinforcement at the flange-to-pipe interface.

 

This article explores their features, complete dimensional specifications under ASME B16.5, types, usage methods, primary applications, a direct comparison with Weld Neck (WN) flanges, and a broader selection guide against threaded and slip-on flanges.

This guide covers SO flange types, ASME B16.5 dimensions, advantages, a simple 5-step installation, a selection comparison table, and 6 FAQs to help you specify the right slip on flange.
