HDPE PE80 and PE100 pipe Properties and Types

Summary :

PE80 pipe refers to the pipe made of 80-grade polyethylene raw material, and PE100 pipe is the pipe made of 100-grade polyethylene raw material. The corresponding 100-level pressure capacity is better than 80-level. Made of PE water supply pipe, the maximum pressure of PE80 pipe is 1.25mpa, and that of PE100 pipe is 1.6mpa. The density of PE80 pipe is lower than that of PE100 pipe, so grade 80 is also called medium density polyethylene (MDPE), and grade 100 is called high density polyethylene (HDPE).

What is HDPE pipe?

HDPE pipe is the replacement product of traditional steel pipe and PVC drinking water pipe. HDPE pipes must withstand a certain pressure, and PE resins with large molecular weight and better mechanical properties, such as HDPE resins, are usually selected.

LDPE resin has low tensile strength, resistance to pressure difference, poor rigidity, poor dimensional stability during molding and difficult connection, and is not suitable as a material for water supply pressure pipes. However, due to its high hygienic index, LDPE, especially LLDPE resin, has become a common material for the production of drinking water pipes.

The grades of HDPE pipe raw materials are divided into PE63 grade, PE80 grade and PE100 grade. Relatively speaking, PE100 grade has the best pressure-bearing performance and the worst flexibility, PE63 has the worst pressure-bearing performance and the best flexibility, and PE80 is between the two. between.

Basically divided into two categories: low density polyethylene LDPE (lower strength); high density polyethylene HDPE. PE materials are divided into five grades according to the international unified standard: PE32 grade, PE40 grade, PE63 grade, PE80 grade and PE100 grade. The production of PE pipes for water supply pipes is high density polyethylene (HDPE)

, its grades are PE80 and PE100 (according to the abbreviation MRS of Minimum Required Strength).

The MRS of PE80 reaches 8MPa; the MRS of PE100 reaches 10MPa.

PE80 pipe (8.00~9.99Mpa) Properties

PE80 pipe is a masterbatch with antimony trioxide content of 80% on polyethylene substrate, which can be mainly used in casting and film making at the same time.

PE80 is a granular free-flowing dust-free masterbatch, which is safer than traditional powder in the production process and easy to master the dosage. It is also considered as a general-purpose masterbatch, and the granular form is free-flowing. The material of the pipe application is PE80.


PE100 pipe Properties

The PE100 pipe letter represents the type of polyethylene 100 grade pipe, which is commonly used in wear-resistant pipelines such as tailings transportation and coal-water slurry transportation).

PE100 refers to the grade. PE100 (100~1.0Mpa) is the number of grades obtained by rounding the minimum required strength (MRS) of polyethylene raw materials. According to GB/T18252, the hydrostatic strength of the material corresponding to 20°C, 50 years, and a predicted probability of 97.5% is determined. σLPL, according to the converted MRS, multiply the MRS by 10 to get the classification number of the material.

PE100 pipe is a kind of PE water supply pipe, not HDPE pipe. PE (polyethylene) material is widely used in the field of water supply pipe manufacturing due to its high strength, corrosion resistance and non-toxicity. Because it will not rust, it is an ideal pipe material to replace ordinary iron water supply pipes.

 What is the difference between PE80 pipe and PE100 pipe

1. Pressure:

The maximum pressure of PE80 pipe is 1.25mpa; while the maximum pressure of PE100 pipe is 1.6mpa.

2. The diameter of the caliber is different

The diameter of the water supply pipe is divided into 26 grades from DN32 to DN1000. Therefore, the diameter of the PE100 pipe is larger than that of the PE80 pipe.

3. Tensile properties:

The tensile yield strength of PE100 pipe is 20% higher than that of PE80 pipe

4. Impact resistance:

The impact resistance of PE100 pipe is higher than that of PE80 pipe

5. Bending performance:

The flexural modulus of PE100 pipe is 20% higher than that of PE80 pipe

PE water supply pipe specifications, models and technical parameters

PE water supply pipes are currently widely used in water supply engineering, especially the caliber DE20-DE500 is the most common. Category: According to the different levels of production raw materials, PE water supply pipes are divided into PE80 and PE100 two grades, at present, China is basically based on these two models of raw materials, the actual production of PE100 more; According to the pressure level, it is divided into five series: SDR11 (1.6Mpa), SDR13.6 (1.25Mpa), SDR17 (1.0Mpa), SDR21 (0.8Mpa) and SDR26 (0.6Mpa). Specifications and models: ΦDE20-1000mmDE is the outer diameter of the label, PE pipe is the use of the outer diameter to mark the caliber, which and the nominal diameter DN is different, according to the outer diameter and the corresponding wall thickness can be calculated the inner diameter, the thickness of the wall thickness corresponds to the size of the pressure level.
