Overview
45° Socket Weld Lateral Tee (Y Tee) is a forged socket weld pipe fitting, designed to create a 45° angled branch from the main pipeline. The socket weld connection provides high sealing strength, perfect for high-pressure, small-diameter piping systems.
All our lateral tees are hot forged from A105 carbon steel, strict dimensional inspection to full nominal size without minus tolerance. We follow ASME B16.11 industry standard, supporting custom pressure classes (3000# / 6000# / 9000#) and all standard inch sizes.
Core Advantages
- Hot forged integrated forming, high pressure & impact resistance
- Socket weld connection, stable welding & tight sealing performance
- 45° Y-type design, gentle fluid flow to reduce flow resistance
- Raw material: Carbon Steel A105, stainless steel SS304/SS316 optional
- Full standard size, zero minus tolerance on OD & wall thickness, no thin-wall cutting corners
- Pressure classes: 3000LB, 6000LB, 9000LB for high-pressure service
- Surface options: Black anti-rust paint, sand blasting, oil coating
- Complete NDT & hydrostatic testing before shipment, full MTC certificates provided

FAQ
Q1: What is the difference between lateral tee and standard straight tee?
A: Straight tee divides flow at 90°, while 45° lateral Y tee branches pipeline at a gentle 45° angle, lowering fluid resistance for smoother medium transportation.
Q2: Do your socket weld lateral tees have minus tolerance on wall thickness?
A: All our forged pipe fittings are strictly manufactured to full standard nominal dimensions, zero minus tolerance on outer diameter and wall thickness, we never cut corners with thin walls.
Q3: What pressure ratings can you offer for this 45° Y tee?
A: Standard pressure classes: 3000LB, 6000LB, 9000LB, fully compliant with ASME B16.11 high-pressure standard.
Q4: Can you supply stainless steel 45° socket weld lateral tee?
A: Yes, we provide SS304 and SS316L stainless steel forged lateral tees upon customer request.
