Product Description

1. look at the appearance

high-quality pe pipe: the inner and outer surfaces of the pipe are smooth and smooth without defects such as bubbles, depressions and impurities.

Inferior PE pipe: the inner and outer surfaces of the pipe are not smooth, not bright, pitted, and the inner and outer surfaces have obvious depressions.

2. Milling Strip

High quality pe pipeline: oil bright, smooth, repeated folding is not easy to break.

Inferior PE pipe: dark color, folding easy to break.

3. welding port

The qualified weld joint shall have smooth and symmetrical flanging along the whole circumference of the pipe, and the low depth of the flanging shall not be lower than the pipe surface; the misalignment at any place on the outer circumference adjacent to the flanging on both sides of the weld shall not exceed 10% of the pipe wall thickness;

High quality PE pipe: flanging smooth and flat. After the joint pressure, the flanging can be longer.

Inferior PE pipe: a large number of pores are produced on the surface after flanging. The flanging is short after the joint pressure.

4. sense of smell

High-quality PE pipe: The product just processed or heated and melted has a slight plastic fragrance, and the cooled product has no peculiar smell.

Inferior PE pipe: a pungent smell.

5. elongation at break

Elongation at break refers to the ratio of the length of the sample to the original length. The higher the elongation at break, the better the flexibility and performance of the product.

High quality PE pipe: stretched to 3.5 times without breaking.

Inferior PE pipe: elongated easy to break, poor toughness.

6. oxidation induction time

Oxidation induction time is the time when the autocatalytic oxidation reaction of the sample starts under the condition of high temperature oxygen, and it is an index to evaluate the thermal degradation resistance of the material in molding, storage, welding and use. The longer the oxidation induction time, the better the aging resistance and the better the performance of the product.

HDPE water supply pipe:

1. Reliable connection: PE pipe systems are connected by electric melting, and the strength of the joint is higher than that of the pipe body.

2, good low temperature impact resistance: PE pipe low temperature embrittlement temperature is very low, can be used safely in the low temperature range. During winter construction, the material will not crack due to its good impact resistance.

3. Good stress cracking resistance: PE pipe has low notch sensitivity, high shear strength and excellent scratch resistance, and its environmental stress cracking resistance is also very prominent.

4, good chemical corrosion resistance: PE pipe can resist the corrosion of a variety of chemical media, the chemical substances in the soil will not cause any degradation of the pipeline. Polyethylene is an electrical insulator, so it does not decay, rust or electrochemical corrosion; in addition, it does not promote algae, bacteria or fungi growth.

5. Aging resistance and long service life: polyethylene pipes containing 2-2.5% evenly distributed carbon black can be stored or used outdoors for 50 years without being damaged by ultraviolet radiation.

6, good wear resistance: PE pipe and steel pipe wear resistance comparison test shows that the wear resistance of PE pipe is 4 times that of steel pipe. In the field of mud transportation, compared with steel pipes, PE pipes have better wear resistance, which means that PE pipes have a longer service life and better economy.

7, good flexibility: the flexibility of PE pipe makes it easy to bend, engineering can bypass obstacles by changing the way of pipe direction, in many occasions, the flexibility of the pipe can reduce the amount of pipe fittings and reduce installation costs.

8. Low water flow resistance: PE pipe has a smooth inner surface, which has a higher conveying capacity than traditional pipe, and also reduces the pressure loss of the pipeline and the energy consumption of water delivery.

9, easy to handle PE pipe than concrete pipe, galvanized pipe and steel pipe lighter, it is easy to handle and install, lower manpower and equipment requirements, means that the installation cost of the project is greatly reduced.
