Insights on steel structures, container homes and modular buildings.
Pipeline steel plate and coil are the raw material for welded line pipe made by ERW, LSAW and SSAW processes. This article covers the plate types PAC STEEL supplies, applicable API and ASTM standards, size ranges and typical applications.
ERW and HFW are closely related but not interchangeable: ERW refers broadly to electric resistance welding, while HFW is the high-frequency subset of it. This article explains both processes, the standards that apply, and how they compare in practice.
DNV, founded in 1864, is one of the leading classification societies worldwide. It is known for strict technical standards and authoritative certification, with services covering shipping, offshore engineering and energy, providing material and product certification for customers globally.
Hydraulic prop tube, axle tube, geological drilling pipe and other seamless pipe categories for the full range of machinery manufacturing requirements.
Sour service seamless pipe for H₂S-bearing oil and gas: standards, chemistry, mechanical properties and procurement notes.
Third party inspection (TPI) is an independent verification process used to confirm that steel products, dimensions, materials, markings, testing, and documents comply with the purchase order, project specification, and applicable standards before shipment.
In the design and procurement of industrial piping systems, carbon steel pipes under ASTM A53 and ASTM A106 standards are often considered side-by-side due to their wide applicability.
Prefabricated steel structures and modular buildings are faster, stronger and more sustainable than traditional construction. See how they compare, where they excel, and what to look for when sourcing.
