Overview

About pipes & fittings

Piping systems are the arteries of industrial plants, carrying everything from high-pressure steam and chemicals to compressed air and water. The integrity of these systems depends on selecting pipes and fittings with the correct wall thickness (schedule) and material grade (e.g., ASTM A106, SS316) to withstand the process conditions.

Fittings and flanges provide the means to change direction, branch off, or connect to equipment. Proper selection of connection types—whether butt-weld, socket-weld, or threaded—ensures leak-free operation and ease of maintenance in Pakistani industrial facilities.

FAQ

Frequently asked questions

Quick answers about sourcing pipes & fittings.

01What is the difference between Schedule 40 and Schedule 80?

Schedule 80 has a thicker wall, allowing it to withstand higher pressures than Schedule 40 for the same pipe size.

02Can you supply pipe gaskets and bolting?

Yes, we provide full kits including spiral-wound gaskets and stud bolts for all flange sizes.

03What is the advantage of seamless pipe over ERW?

Seamless pipe has no welded seam, making it preferred for high-pressure and critical applications.

04Do you offer pipe cutting and threading services?

We can supply pipes pre-cut to length and threaded to your requirements.
