PE & HDPE Pipe PE100 is the third generation of pipe grade PE. It has an optimum balance of three key properties: Minimum Required Strength (MRS) – this provides long-term strength and creep resistance. Stress crack resistance (sometimes referred to as slow crack growth resistance). Puhui Pipe manufacturer in China
materials must withstand a hoop stress of 10 MPa, for 50 years at room temperature [3]. In contrast, the mechanisms involved in long terms degradation and malfunctions of HDPE gravity sewer pipes are radically different from those affecting pressure pipes [4].
Pressure and Temperature Maximum temperature of HDPE pipe is the lowest among plastic pipes. Depending on manufacturer, its upper long term temperature limit is 140 o F (60 o C and has a short high temperature exposure of 175 o F (80 o C.
The specific heat of polyethylene varies with temperature from 1800 Joules/kg.K at 0 C to 2200 J/kg.K at 60 C. At temperatures above 25 C it is necessary to rerate polyethylene pipe systems. The table below provides guidance as to the maximum operating

The recycling nuer for HDPE is #2. HDPE is a very commonly recycled type of plastic and is well accepted in most recycling centers. What are HDPE’s properties? High tensile strength (maximum stress a material can withstand) Density above 0.95 – 0.97 g
3 Rules for Choice of Pipe Weight PRESSURE CLASS DESIGNATION SCLAIRPIPE® high density polyethylene (HDPE) pipe pressure class ratings are designated by a Dimension Ratio (DR) nuer. This is a common “rating” system specified by ASTM, AWWA
Plastic Pipes Temperature Derating Diagram Example - Higher Temperature and Reduced Strength If the operating pressure for a 6" Schedule 80 CPVC pipe is 167 psi, the maximum operating pressure at 150 o F (66 o C) is reduced to (167 psi) 0.5 = 83.5 psi
Unpigmented HDPE is preferred. Natural material has the highest value as a recycled stream since it has the widest variety of end-use appliions. It is the most cost effective to process through the recycling system. Optical brighteners are detrimental to recycling. Puhui Pipe manufacturer in China
HDPE will absorb less than 0.01% water in 24 hours at room temperature. This means that drying is not normally necessary. If it is, dry in a hot air oven for 3 hours at 65 C. HDPE is available in both granular and powder form. The powder form is cheaper but can give Puhui Pipe manufacturer in China
25/10/2016· Using HDPE Safely Given its high durability and resistance to most damage, HDPE has become a popular material for use in commercial buildings. At Scranton Products, our HDPE products even come with a GREENGuard Gold Certifiion, making them suitable for use in areas where occupants are considered especially sensitive, like hospitals and schools.

Jan 16, 2016 - I have learned to melt down HDPE. Always looking for ideas of "thing" to make as well as teach my grandkids recycling etc. . See more ideas about Recycling
12/11/2014· How to Recycle HDPE Plastic the Easy Way: After spending 2 hours cutting up a single milk bottle with kitchen shears, I knew I couldn''t do it again.I felt like a late night infomercial and may have actually uttered the phrase, "There has to be a better way!"Turning
9 It is clear from these observations that u sing recycled HDPE instead of raw HDPE can create significant environmental and economic benefits. T herefore, this work focuses on finding a way to use rHDPE instead of raw HDPE in rotational molding. 1.2 Aims Puhui Pipe manufacturer in China
Maximum Short Time Operating Temperature - for pipes without pressure. PVC : 95 o C PP : 100 o C PE : 95 o C Heat Distortion Temperature - is the temperature where a test piece of a material placed in a heat medium with a bending load (18.6 kg/cm 2) applied - reaches a specified deflection.

Polyethylene is a whitish, semi-crystalline, and effectively opaque engineering thermoplastic which, chemically, is a very high molecular weight (3-6 million) HDPE. As a result, its melt viscosity is extremely high and normally can only be processed by powder Puhui Pipe manufacturer in China
Operating temperatures are limited to 85 F maximum and 32 F minimum. • Operating pressure is limited to 150 psi or the rating of the pipe, whichever is less. FTS423-H TAPPING SLEEVE FOR USE ON HIGH DENSITY POLYETHYLENE PIPE (HDPE)
