Based in Houston, USA, Vipul Pipes and Tubes is a reputable and top supplier of 317L stainless steel pipe fittings made for high-temperature and corrosive service environments. Compared to regular 316L, SS 317L, a low-carbon, high-molybdenum austenitic stainless steel, provides improved resistance to pitting, crevice corrosion, and chemical attack. Industries like pulp and paper, petrochemicals, and marine processing make extensive use of these fittings. Vipul produces a wide variety of buttweld fittings, such as elbows, tees, reducers, and caps, in accordance with ASTM A403 specifications for remarkable corrosion resistance, weldability, and strength.

Vipul Pipes and Tubes’ 317L stainless steel pipe fittings are made of 18–20% chromium, 11–15% nickel, 3-4% molybdenum, and ≤0.03% carbon, with additional elements like silicon and manganese. Weldability and resistance to intergranular corrosion are improved by the low carbon content. These fittings provide excellent corrosion resistance in acidic environments, as well as tensile strength ≥515 MPa, yield strength ≥205 MPa, and elongation ≥35%. Because of its exceptional ability to withstand sulphur- and chloride-rich environments, SS 317L is appropriate for welded structures subjected to demanding industrial settings.

The stainless steel 317L pipe fittings from Vipul Pipes and Tubes are extensively utilised in nuclear power systems, pulp and paper industries, chemical processing facilities, pharmaceutical equipment, and maritime settings. Increased protection against localised corrosion is provided by the high molybdenum content, particularly in systems that transport saline fluids, acids, and chlorides. These fittings are perfect for pollution control devices, condensers, process piping, and heat exchangers. For high-purity and high-corrosion service pipelines that require extended service life and dependability, SS 317L is a good option because of its low carbon content, which guarantees optimal performance after welding.
