HDPE pipe is a type of flexible plastic pipe used for fluid and gas transfer and is often used to replace ageing concrete or steel mains pipelines. Ducts commonly also deliver ventilation air as part of the supply air. The needed airflows include, for example, supply air, return air, and exhaust air. PP-R pipes also may include reinforcement layers for benefits such as reducing longitudinal thermal expansion / contraction.ĭuct Pipe: Ducts are conduits or passages used in heating, ventilation, and air conditioning (HVAC) to deliver and remove air. PP-R piping products are rated for continuous operation at 82Cº temperature, with pressure ratings dependent on their wall type (SDR). PP-R is a copolymer of propylene and at least one comonomer, where the propylene is more than 50% of the composition. PP Random Copolymer (PP-R): PP-R means polypropylene random copolymer.

Delivers long term economy, value, and dependability.

Electro fusion & Butt fused joints eliminate need for thrust blocks.

Safer due to operating pressure capabilities.

Frozen water will not crack or break HDPE pipe.

Carbon black is added to HDPE to provide UV protection.

Systems maintain high fluid flow properties throughout their service life due to excellent chemical and abrasion resistance.

Withstands freezing water better than traditional metal piping.

Underground piping meets or exceeds operating temperatures and pressures.

Pipe are available in coils form ½ “to 4” & up to 12 Mtrs of any size.

PPH: Available Sizes: 20 mm to 355 mm AS PER DIN Standard

With the combination of excellent chemical resistance and the ability to be joined and welded by heat fusion makes this an ideal plastic for piping system, chemical tanks and structures in corrosive environments. Polypropylene homopolymer or PPH for short is stronger and stiffer than copolymer and more widely used. Both have very similar properties but appearance and performance differences are distinctive between the two types. PP-Homopolymer (PP-H): Polypropylene is available in two main grades, Polypropylene homopolymer and Polypropylene copolymer.
