PE water supply pipe sample condition adjustment and experimental specifications The natural environment is in accordance with GB/T2918, the temperature is 232, the condition adjustment time is 24h, and the experimental method specifications stipulate that the experimental method specifications shall be followed.

Tone and shape of PE water supply pipe:

Observe with the naked eye whether the thickness and outer diameter specified in our country are reached.

给大家介绍一下关于PE供水管外形及尺寸

  PE water supply pipeThe size of the detection:

1. Length: Measure straight pipe with 1mm steel tape.

2. Average outer diameter: Measure the average outer diameter correctly according to GB/T8806.

3. Thickness and error: accurately measure the thickness and error of the pipe according to GB/T8806.

4. Carbon black composition: in accordance with the provisions of GB/T13021.

5, pigment and carbon black dispersion: in accordance with the provisions of GB/T18251, select the tabletting sample preparation method.

6. Oxidation induction time: according to GB/T17391, the sample comes from the inner surface layer of the pipe, and the embrittled sample comes from the surface layer cut by 0.4mm from the embrittlement surface layer of the exposed pipe sample.

7, melt flow rate: in accordance with the provisions of GB/T3682.

8. Hydrostatic strength: according to the provisions of GB/T6111, the medium inside and outside the pipe is water, you can choose type a or type B joints, and choose type a joints during arbitration.

9. Elongation at break: according to GB/T8804.2, when the thickness of the tube suitable for the elongation at break test is less than 12mm, the embrittlement sample shall come from the exposed side of the tube.

10. Longitudinal shrinkage rate: according to GB/T6671.2, for trachea with an outer diameter of more than 200mm, longitudinally cut tracheal spline experiment can be applied, and the experimental temperature is 1102.

11. Aging resistance: Pipes with nominal pressure outer diameter of 82mm and SDR11 shall be selected. When the manufacturer's air pipe specification exceeds nominal pressure outer diameter of 32mm, the manufactured air pipe with small nominal pressure outer diameter and large SDR shall be selected for exposure according to GB/T3681. Then, hydrostatic strength test shall be carried out at 7.8, elongation at break shall be measured at 7.9, and oxidation induction time shall be measured at 7.6.

12, environmental health characteristics: should choose the manufacturer's nominal pressure outside diameter of the pipe, in accordance with the provisions of GB/T17219.
