Liam Pipes & Tubes is a well-established manufacturer and exporter of Stainless Steel 316 and 316L EFW (Electric Fusion Welded) Pipes based in Houston, USA. They are well-known for their excellent corrosion resistance, weldability, and harsh industrial conditions durability. SS 316 also has molybdenum added for improved resistance to chlorides and acidic environments, while its low-carbon version, 316L, reduces carbide precipitation when welded. Our EFW pipes, produced as per ASTM A358 specifications, are best suited for pressure vessels, chemical processing plants, food-grade processing, and marine systems where strength, hygiene, and corrosion protection are needed.
SS 316/316L pipes have 16–18% Cr, 10–14% Ni, 2–3% Mo, and ≤0.08% C (316) or ≤0.03% C (316L). The EFW pipes have tensile strength ~515 MPa, yield strength ~205 MPa, and ~35% elongation. They have remarkable resistance to pitting, crevice corrosion, and acid environments. 316L enhances weldability and minimizes intergranular corrosion. EFW welding provides strong longitudinal seams, appropriate for large-diameter and heavy-wall pipes in pressure systems. Their toughness, malleability, and resistance to corrosion make them dependable for chemically corrosive or seawater services.
