We are widely known for offering premium quality STEEL THREADED FLANGES. Designed and developed in compliance with international quality standards, these stainless steel threaded flanges are made to suit the variegated requirements of diverse industries. Our product stainless steel threaded flanges are shock proof and ensures high utility with low maintenance. Customizations of these steel threaded flanges are done as per the diverse demand & specifications of the clients all across the world.
Threaded Flanges (Screwed flanges)are similar to slip-on flanges in outline, but the bore is threaded, thus enabling assembly without welding. This obviously limits its application to relatively low pressure piping systems. Threaded Flanges may be welded around the joint after assembly, but this is not considered a satisfactory method of increasing the flanges' pressure applications. Threaded flange use in low press condition usually.

Notes:-
The threaded flanges conforms to ASME B1. 20.1 NTP threads. (The only exceptions are small male and female plain face threaded flanges which use NPSL locknut threads)
Class 300 and higher threaded flanges are counter-bored. Threads are chamfered to the counterbore at an angle of 450 (approx)
Weights are based on manufacturer's data and are approximate
