What is interfacial pressure HDPE pipe?
Interfacial pressure is used to calculate a fusion joining gauge pressure value for hydraulic butt fusion machines or manual machines equipped with force reading capability. The interfacial pressure is constant for all pipe sizes and all butt fusion machines.
What is the pressure rating of HDPE pipe?
Typically the standard specification identify class of a HDPE pipe is by the nominal pressure class – PN – up to PN 20 or 20 bar.
What is the properties of HDPE pipe?
HDPE pipe is a flexible plastic pipe made of thermoplastic high-density polyethylene widely used for low-temperature fluid and gas transfer….Properties of HDPE Pipes.
| Mechanical Properties | HDPE Properties |
|---|---|
| Yield Strength | 18-26 Mpa |
| Elongation | 10% |
| Elastic Modulus | 900 Mpa |
| Hardness | 61 Rockwell (Shore) |
What is PE100 HDPE?
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). Rapid crack propagation resistance.
What is fusion pressure?
This process develops pressure, causing flow of the melted materials, which causes mixing and fusion. When the thermoplastic pipe is heated, the molecular structure is transformed from a crystalline state into an amorphous condition. When fusion pressure is applied, the molecules from each pipe end mix.
What is the maximum size of an HDPE compression fitting?
For 75–125mm: max.
What is PE and PN in HDPE pipe?
The PN abbreviation used after the size of the polyethylene pipe represents the maximum pressure that the pipe can withstand; just like PN 16 PE100 DN63 that is a HDPE Pipe made of PE100 material and 63 mm in diameter, and should withstand a pressure of 16 bar.
