Steel procurement guides and project supply notes.
ERW, LSAW and SSAW cover different diameter and pressure windows. Here is where each process fits - and where it does not - based on our production ranges and project supply record.
Fire protection procurement usually means five suppliers and five inspection teams. Supplying pipe, grooved fittings, press fittings and valves from one source cuts interfaces and keeps schedules.
Compression, welding, flange, crimp and cone-thread are the five common ways to join seamless steel pipe. Compare them by pressure, size and maintenance needs before you order.
SS304 (18-8) is the cost-effective general-purpose grade; SS316 (18-10) adds alloying elements for higher chloride and pitting resistance. Here is how to choose between them.
A53 covers black and hot-dip galvanized welded and seamless pipe for general service; A106 covers seamless carbon steel pipe for high-temperature service. Compare chemistry and availability.
Seamless stainless pipe is drawn from a solid billet with no weld seam; welded pipe is formed from strip and joined at a seam. Compare pressure, length, cost and corrosion behaviour.
A flange is the bolted connection between pipe, valve and equipment. Learn what a flange joint consists of, which materials are used, and how to select one for leak-free service.
API 5L covers seamless and welded line pipe for oil and gas transmission. PSL2 adds mandatory carbon equivalent, toughness, yield and NDT requirements over PSL1. Here is how to specify.
ASTM A106 Grade B is the seamless carbon steel pipe specified for high-temperature service. Understand what the grade covers and what to confirm before you order.
Use the standard formula W = 0.02466 x wall thickness x (outside diameter - wall thickness) to estimate welded steel pipe weight per metre before you order or quote freight.
