PE Corrugated Pipe Oblique Tee

Structure & Sealing Performance

Flow-optimized Streamlined Design: 

Its streamlined inner profile enables branch flow to merge smoothly along the main pipe direction. It eliminates turbulence and air resistance caused by right-angle impact, minimizing debris buildup and blockage at junctions.

Corrugated Pipe Compatible Structure: 

Specially developed for PE double-wall corrugated pipes and steel-belt reinforced corrugated pipes. Perfect dimensional matching guarantees overall ring stiffness and reliable sealing after assembly.

Versatile Connection Options: 

Elastomeric gasket socket-spigot joint, hot-fusion welding and electro-fusion welding are available per pipe size and project requirements. Easy installation prevents underground water and sediment infiltration.

Material & Advantages

Premium HDPE Material: 

Constructed from high-density polyethylene (HDPE). It delivers excellent corrosion resistance, ageing resistance and flexibility, performing well in harsh underground acidalkali soil with over 50-year buried service life.

Smooth Inner Wall: 

Precision-finished inner wall provides low hydraulic resistance for smooth flow transfer, scaling resistance and reduced pumping energy consumption.

Pressure & Crack Resistance:

Upgraded versions adopt reinforcing ribs or corrugated transition structures at joint positions, greatly boosting pressure bearing and impact resistance.
