Technical standards for PE non-excavation crossing pipes

  材料是聚乙烯,是塑料材料中用量最大的品种,它是由聚乙烯合成的高分子材料。 The material used for PE non-excavation crossing pipes is polyethylene, which is the largest amount of plastic materials. It is a polymer material synthesized from polyethylene. 基本分为两类:低密度聚乙烯 LDPE(强度较低);高密度聚乙烯HDPE。 This material is basically divided into two categories: low density polyethylene LDPE (lower strength); high density polyethylene HDPE. PE materials are divided into five grades according to internationally unified standards: PE32, PE40, PE63, PE80 and PE100.

用于 PE非开挖穿越管材 高密度聚乙烯 HDPE,其等级是PE80、PE100两种(依据最小要求强度MinimumRequired Strength的缩写MRS)。 For PE non-excavation through pipes , high-density polyethylene HDPE, its grades are PE80, PE100 (based on the Minimum Required Strength Abbreviation MRS). The MRS of PE80 reaches 8MPa; the MRS of PE100 reaches 10MPa. MRS refers to the hoop tensile stress intensity (calculated according to international standards).

PE80 (8.00 ~ 9.99Mpa) is a masterbatch with an antimony trioxide content of 80% on a polyethylene substrate. It can be mainly used in casting and film making at the same time. 掌握 剂量,也被认为是通用母料,颗粒状可自由流动。 It is a granular, free-flowing, dust-free masterbatch. It is safer than traditional powders in the production process, and it is easy to grasp the dosage. It is also considered as a universal masterbatch, and the granules can flow freely.

PE100 (10.00 ~ 11.19Mpa) is the number of grades obtained after rounding the minimum required strength (MRS) of polyethylene raw materials. The hydrostatic strength corresponding to 20 ℃, 50 years, and the predicted probability of 97.5% is determined according to GB / T18252 .

The production of PE non-excavation through pipes must be carried out in accordance with this standard. The industry specifications of PE pipes are becoming more and more complete. It is believed that it will lead the trend of non-excavation projects.
