7W Equal Long Weld Tee

The 7W Equal Long Weld Tee is a premium sanitary welded fitting designed to create a branch connection in stainless steel piping systems where all three ends are of equal diameter and feature an extended weld length for added strength and welding convenience. Manufactured from high-grade 304 or 316L stainless steel with a polished interior finish, this long weld tee delivers exceptional durability, corrosion resistance, and hygienic performance for demanding sanitary applications.

Key Features

  • Premium 304/316L Stainless Steel Construction – Offers outstanding resistance to corrosion, oxidation, and chemical attack, ensuring long service life in aggressive processing environments.

  • Equal Diameter on All Three Ends – The equal tee configuration maintains consistent flow cross‑section, minimizing pressure drop and turbulence through the branch.

  • Extended Weld Ends – The longer weld spools provide increased welding area, resulting in stronger, more reliable joints and easier alignment during installation – especially beneficial for thicker pipe schedules.

  • Polished Interior Surface – The smooth internal finish reduces bacterial adhesion and product residue buildup, facilitating thorough Clean‑In‑Place cleaning and preventing contamination.

  • Permanent Butt Weld Connection – The welded ends create a permanent, leak‑free joint that outperforms mechanical fittings in high‑vibration, high‑temperature, and high‑pressure applications.

How It Works

The 7W Equal Long Weld Tee functions as a three‑way branch fitting that enables fluid or gas to flow from the main pipeline into a branch line of the same diameter.

  1. Main Line Connection – Two ends of the tee are welded inline with the main process pipeline, creating a continuous straight‑through flow path.

  2. Branch Line Connection – The third end is welded to a secondary pipeline, allowing flow to be diverted from the main line at a 90° angle.

  3. Equal Diameter Design – Because all three ends have the same inner diameter, the flow velocity and pressure remain balanced across all branches, minimising turbulence and product degradation.

  4. Extended Weld Ends – The longer weld spools offer additional material for secure welding, particularly useful when connecting to thicker pipe walls or when future weld repairs may be needed.

Why Choose Our 7W Equal Long Weld Tee?

  • Superior Material Quality – Made from 304 or 316L stainless steel, offering excellent corrosion resistance and mechanical strength for demanding sanitary environments.
