hdpe pipe expansion and contraction manufacture

HDPE PIPE

We manufacture and supply co-extruded HDPE pipe in various colours and ranges from 20mm to 1200mm in diameter and coils from 40mm to 160mm. ADVANTAGES: Designed for use in high temperatures. Reduced temperature rise in contents conveyed. Thinner pipe means lower purchase cost. Greater hydraulic capacity. Reduced contraction and expansion

PE Temperature Considerations - Vinidex Pty Ltd

Expansion and Contraction. Expansion and contraction of PE pipes occurs with changes in the pipe material service temperature. This is in common with all pipe materials and in order to determine the actual amount of expansion or contraction, the actual temperature change, and the degree of restraint of the installed pipeline need to be known.

HIGH DENSITY POLYETHYLENE PIPE HDPE

HDPE has a high coefficient of thermal expansion and contraction along with a low modulus of elasticity. This sensitivity to pressure and temperature causes HDPE to expand and contract more than traditional water and sewer piping materials. The potential pipe expansion or contraction must be considered when asseling bolt on fittings.
