Weld Tee, also known as Butt Weld Tee (BW Tee), is a core forged pipe fitting designed to create 90° branch pipelines in industrial fluid transmission systems. With T-shaped three-way structure, it divides or converges fluid flow from main pipelines to branch lines. Adopting butt welding connection method, both ends are processed with standard bevel for full penetration welding, forming an integrated, leak-proof piping system. Compared with socket tee and threaded tee, weld tee owns higher pressure bearing capacity and stronger structural stability, widely recognized as the standard fitting for high-pressure critical industrial piping projects worldwide.
Production Technology & Quality Advantages
All our weld tees are manufactured by integral hot forging and precise CNC machining, fully complying with ASME B16.9 international dimensional standards. We select premium raw carbon steel, stainless steel, alloy and duplex steel with complete original MTR material certification. The inner flow channel is finely polished to eliminate sharp corners, greatly reducing fluid turbulence and pressure loss. Every batch of weld tees undergoes strict heat treatment to optimize internal metal texture, improving tensile strength and impact resistance. 100% non-destructive testing (UT/RT/PT) and hydrostatic pressure inspection are carried out to eliminate forging cracks, shrinkage cavities and other hidden defects, guarantee stable sealing performance under long-term high temperature and high pressure service.
Complete Specifications & Diversified Types
We supply full series weld tees covering equal tee and reducing tee two main types. Equal weld tee owns identical diameter for three ports for uniform flow distribution; reducing weld tee features smaller branch port to match branch pipeline with smaller flow demand. Size range covers DN15 to DN1200, matching all SCH wall thickness grades. Standard beveled ends perfectly match butt-weld pipes, elbows, flanges and other fittings. Custom non-standard dimensions, special wall thickness and alloy material tees are available per customer drawings or samples, with strict dimensional tolerance control to ensure seamless on-site assembly.
Application Industries
Weld tees are widely applied in petroleum, natural gas, petrochemical refinery, thermal power station, chemical reaction pipelines, water treatment, food pharmaceutical, marine offshore engineering, LNG cryogenic transmission and heavy machinery piping systems. It is the preferred branch fitting for high-pressure, high-temperature and corrosive medium transportation, capable of adapting long-cycle continuous operation and harsh industrial working environments.
Factory Service Advantages
As a professional manufacturer and exporter of welded pipe fittings, we provide one-stop custom service for weld tees including material, size, surface anti-rust treatment and special marking. All products adopt standard export wooden crate packaging with anti-rust oil to avoid rust and collision damage during long-distance sea transportation. Complete ISO, CE and material test documents can be provided to meet global engineering acceptance standards. Sufficient stock for standard sizes, flexible production cycle for bulk orders, competitive factory wholesale price, support small batch sample customization. Welcome global engineering contractors, pipeline distributors and factory purchasers to send inquiries for technical parameters and quotation.
