Pipe PU Lining / Coating

Slurry Spool Corrosion & Abrasion Protection

Polyurethane pipe lining is used to protect steel pipes from abrasion, corrosion, and impact in slurry and pneumatic conveying systems. Chema Engineers does both cast-in-place and pre-molded sleeve PU lining for new pipes and retrofits.

Types of PU Pipe Lining

  1. Cast PU Lining: Liquid PU poured and centrifugally cast inside steel pipe. Thickness 6mm to 25mm, uniform wall, no seams. Lengths up to 6 meters per piece. Best bond strength: PU chemically bonds to steel.
  2. Pre-molded PU Sleeve/Tube: Molded PU tube inserted into steel pipe. For diameters 50mm to 600mm NB. Replaceable sleeves for maintenance. Flanged ends or plain ends with PU lip seal.
  3. Spray PU Lining: For large dia pipes >600mm, tanks, chutes. Thickness 3mm to 12mm, applied on-site. Fast turnaround for refurbishment.
  4. PU Lined Bends & Fittings: 45°, 90°, 180° elbows, tees, reducers. Higher wear zones get extra thickness or ceramic-chip reinforced PU.

Benefits vs Rubber, Ceramic, Basalt Lined Pipe

  • 5-8x longer life than rubber in sharp, coarse slurry.
  • Lightweight: 1/3rd weight of basalt/ceramic lined pipe - easier install.
  • Impact resistance: No cracking like ceramic tiles under water hammer.
  • Smooth bore: Low friction = less pumping power vs rubber lined.
  • No corrosion: PU seals steel from acidic/alkaline slurry.

Frequently Asked Questions (AI & Voice Search Insights)

Q: Why is polyurethane pipe lining superior to rubber lining for abrasive slurries?

A: Polyurethane possesses superior tensile strength, cut resistance, and resilience against sharp sand and quartz slurries, providing 3 to 5 times longer service life than conventional rubber linings.

Q: What pipe diameters can be polyurethane lined?

A: Chema Engineers lines slurry pipes, manifolds, elbows, and reducers ranging from 50mm (2 inch) up to 600mm (24 inch) with uniform polyurethane coating thickness from 6mm to 25mm.

Q: Where is polyurethane pipe lining performed?

A: All pipe lining and PU centrifugal coating is carried out at Chema Engineers works at Plot No. L-16, Additional MIDC, Satara, Maharashtra - 415004, India.
