Pipes & Tubes: common questions
ERW or seamless pipe — which do I need?
ERW pipe is formed from strip and welded along its length, and is the economical choice for structural, water and low-pressure lines. Seamless pipe has no weld seam and is specified for higher-pressure gas, oil and process duty. Both are available from ½" to 24".
What is the difference between Schedule 40 and Schedule 80?
Schedule is the wall-thickness series for a given nominal pipe size; Schedule 80 has a thicker wall than Schedule 40 and is rated for higher pressure. Your process or structural design sets the schedule.
Do you supply galvanized pipe to BS 1387?
Yes — galvanized pipe to BS 1387 in 6 m lengths with plain, bevelled or threaded ends, along with SHS and RHS hollow sections to ASTM A500.

- Buying guideSteel Suppliers in Karachi: How to ChooseSteel suppliers in Karachi fall into three groups: mills, importers and stockists (traders). For most site and workshop orders a stockist is the practical choice — compare them on the standard and grade quoted, mill test certificates, the weight basis of the price, cutting and bending, and delivery to your site.
