- SCH 5S – XXS
- 1/2" – 48" NB
Lateral Tee (Y-Tee) Manufacturer in India
Sawariya Metal Industries is a manufacturer, supplier, stockist and exporter of Lateral Tee (Y-Tee) in stainless steel, carbon steel, alloy steel, duplex, nickel alloy and other grades, in a wide range of sizes and pressure ratings.
A lateral tee has a branch at 45° (or another angle) to the run, giving a smoother flow path than a 90° tee for slurry, drainage and solids handling.
Buttweld fittings are bevelled at the ends and welded directly to the pipe, giving a continuous, leak-resistant joint with a smooth bore and low pressure drop. They are the standard choice for process piping above 2" NB and for high-pressure, high-temperature service.
Key Features of Lateral Tee (Y-Tee)
45° Branch
Lower turbulence than a 90° tee.
Solids Handling
Suitable for slurry and drainage lines.
Smooth Flow
Butt-welded joints give a smooth bore and low pressure drop.
High-Pressure Ready
Suited to high-pressure, high-temperature service.

Related Buttweld Fittings
90 Degree Long Radius Elbow
A 90° long radius (LR) elbow changes the pipe direction by 90° with a centre-to-end radius of 1.5 times the nominal pipe size, giving lower pressure drop and smoother flow than a short radius elbow.
90 Degree Short Radius Elbow
A 90° short radius (SR) elbow has a centre-to-end radius equal to the nominal pipe size (1D), allowing a tight 90° turn where space is limited.
45 Degree Elbow
A 45° buttweld elbow changes the pipe direction by 45° and is used for gradual direction changes, offsets and lateral routing with minimal pressure loss.
Technical Note: Dimensions, pressure ratings and material properties should be verified against the applicable ASME / MSS / DIN / ISO standard, approved drawings, purchase order and Mill Test Certificate (MTC) before final use.
