Stainless steel 317 buttweld fittings have excellent corrosion resistance and high strength, making them ideal for demanding applications. They come in seamless and welded forms and are available in various types such as elbows, tees, reducers, caps, stub ends, and cross fittings. These fittings comply with ASME/ANSI B16.9 standards and are available in sizes from 1/2"NB to 48"NB and thicknesses from Schedule 5S to XXS. The 317 grade is particularly resistant to chemical attack, making these fittings suitable for chemical processing, petrochemicals, and power generation industries.

Stainless steel 317 equal tees are integral components in piping systems, offering robust performance in corrosive and high-temperature environments. These tees are designed to split flow equally in three directions, maintaining fluid integrity and system efficiency. Manufactured to ASME/ANSI B16.9 standards, they are available in seamless and welded forms, ensuring versatility in installation. This makes 317 stainless steel equal tees suitable for applications in chemical processing plants, pharmaceutical industries, and offshore oil and gas platforms, where maintaining fluid integrity and system reliability are paramount.

Stainless steel 317 pipe fittings undergo a meticulous manufacturing process to ensure they meet stringent industry standards and perform reliably in harsh environments. Starting with the selection of high-quality 317-grade stainless steel, the raw material is carefully cut and shaped to precise dimensions using advanced cutting and forming techniques. Cold forming and hot forming methods are employed based on the size and complexity of the fittings required. Machining operations such as drilling, threading, and finishing follow to achieve the desired surface smoothness and dimensional accuracy.

After shaping and machining, the fittings are assembled using welding processes that ensure strong and leak-free joints. Post-assembly, heat treatment procedures may be applied to enhance the fittings' mechanical properties and relieve residual stresses. Throughout the manufacturing process, rigorous quality control measures, including dimensional inspections and non-destructive testing like ultrasonic testing, are conducted to verify the integrity and performance of the fittings. This meticulous approach ensures that stainless steel 317 pipe fittings deliver durability, corrosion resistance, and reliability required by industries such as chemical processing, pharmaceuticals, and offshore applications.
