We have a year-round inventory of 150 tons of pipe fittings, and regular sizes can be shipped within two weeks, effectively relieving your inventory pressure. Our factory has passed ISO, PED, and NORSOK M650 certifications, and all products undergo 100% non-destructive testing to ensure reliable quality. With the advantage of large-scale production, even small batch orders can enjoy preferential prices, truly reducing costs and increasing efficiency for you.
Welding elbows are mainly distinguished based on the bending angle and bending radius. The most commonly used angles are 90 degrees and 45 degrees, used to achieve pipeline turning. The radius is divided into long radius (LR) and short radius (SR).
- The bending radius of a long radius elbow is 1.5 times the diameter of the pipe, with low fluid resistance, and is the default standard selection
- The radius of a short radius elbow is equal to the pipe diameter and is usually used in situations where installation space is limited
SMLSCO can provide a full range of butt welded elbows to meet different working conditions.
WP317L is a reinforced austenitic stainless steel made of 316L. Its key advantage lies in its higher molybdenum (Mo) content (usually greater than 3%), which makes it significantly superior to 316L in terms of resistance to overall corrosion, especially pitting and crevice corrosion in chloride environments. This characteristic makes WP317L an ideal choice in more corrosive and harsh environments, providing longer service life and higher safety guarantees for critical equipment.

With its excellent corrosion resistance, WP317L elbows are mainly used in highly corrosive industrial environments. It plays a key role in flue gas desulfurization (FGD) systems, pulp and paper industry, textile printing and dyeing equipment, and chemical plants that process various highly corrosive compounds such as sulfur-containing compounds. Large diameter elbows such as 12 inches are commonly used in the core process pipelines of these industries to ensure the long-term stable operation of the pipeline system.
