Product Description
Grade 904L introduction
Grade 904L introduction
Grade 904L stainless steel is a non-stabilized austenitic stainless steel with low carbon content. This high alloy stainless steel is added with copper to improve its resistance to strong reducing acids, such as sulphuric acid. The steel is also resistant to stress corrosion cracking and crevice corrosion. Grade 904L is non-magnetic, and offers excellent formability, toughness and weldability. Grade 904L contains high amounts of expensive ingredients, such as molybdenum and nickel. Today, most of the applications that employ grade 904L are replaced by low-cost duplex stainless steel 2205.

Introduction to common type of Butt Welding Straight Tee
Introduction to common type of Butt Welding Straight Tee
A Butt Weld (BW) Tee is a T-shaped pipe fitting with three outlets, used to branch, divide, or combine piping flow, primarily in high-pressure or critical applications. Welded directly to pipes for a leak-proof seal, they are manufactured in equal (straight) or reducing sizes. Commonly made from carbon or stainless steel, they adhere to standards like ASME B16.9

Product processing
BW (Butt-Weld) tee production primarily involves hydraulic bulging or hot extrusion to form a T-shape from a steel pipe blank. The process includes raw material cutting, heating/pressing, branch extrusion, trimming, sizing, and heat treatment to ensure uniform wall thickness, followed by beveling and inspection
Key Production Steps
1. Material Selection & Cutting: High-quality steel pipe (carbon or stainless) is cut to specific lengths based on the tee size.
2. Forming Method:
1. Material Selection & Cutting: High-quality steel pipe (carbon or stainless) is cut to specific lengths based on the tee size.
2. Forming Method:
* Hydraulic Bulging (Cold/Warm): A straight pipe blank is placed into a die. Hydraulic cylinders exert pressure on both ends,and liquid inside pushes the branch outlet out, forming the T-shape.
* Hot Extrusion (Hot Forming): The pipe blank is heated to forging temperature, and a die presses the branch outlet while simultaneously forming the main body.
3. Branch Finishing: The branch outlet created in the forming process is trimmed to the correct length.
4. Heat Treatment: To reduce work hardening from the forming process and improve material structure, the tee undergoes heat treatment (annealing or normalizing).
5. Sizing/Shaping: The formed tee is pressed to meet exact dimensional tolerances.
6. Beveling (Butt-Weld End Preparation): Ends are beveled for welding (typically in accordance with ASME/ANSI standards).
7. Final Inspection & Testing: Inspections include visual inspection, dimensional checks, nondestructive testing (NDT) such as dye penetrant or magnetic particle testing to ensure integrity.
