Ldpe Pipes and Fittings
LPDE PIPE AND SPECIFICATIONS
LDPE Pipe, Polyethylene was used as the first product in 1955, LDPE (Low Density Polyethylene) is a thermoplastic pipe occurring for petroleum. Using a high-pressure process (1600 atm and 200 ° C in the reactor tube) made by free radical polymerization LDPE pipes are manufactured on the same production conditions today. LDPE pipes due to differences in their molecular structure according to the HDPE pipe LDPE has a lower crystallity.
LDPE pipes for this reason, the resistance is also low chemical resistance.LDPE pipes In contrast, impact resistance is higher. The density of the LDPE is available between -40-70 ° C 0.91-0.92 g / cm³.
LDPE is unreactive at room temperature outside the high oxidation factors. LDPE is unreactive at room temperature outside the high oxidation factors.
- LDPE 0.910 to 0.940 g / cm3 is defined range.
- LDPE pipes continuous at 80 ° C and 95 ° C can withstand a short time.
- LDPE pipes Fully flexible translucent or opaque occurs with almost no variation and is strong enough to be broken.
LDPE pipes have the specifications shown below
- Maximum temperature: 176 ° F (80 ° C)
- Lowest temperature: -58 ° F (-50 ° C)
- Melting point: 248 ° F (120 ° C)
- Tensile strength: 1700 psi (11.7 MPa)
- Hardness: SD55
- UV resistance: poor
