HDPE双壁缠绕管质量该如何区分?

作者: laobingguandao    来源:http://www.laobingguandao.com  时间:2020-08-20    人气:
怎么经过外观和实验区分HDPE双壁缠绕管质量,能够经过以下七种办法进行:HDPE双壁缠绕管色彩,要求管材内外层各自的色彩均匀共同,外层一般为黑色,其他色彩能够由供需双方商定,也能够由厂家规划色彩,常见的内壁色彩有蓝色、黑色、黄色三种色彩。 HDPE双壁波纹管外观 HDPE双壁缠绕管管材内外壁不答应有气泡、洼陷、显着的杂质和不规则的波纹。
How to distinguish the quality of HDPE Double wall winding pipe through appearance and experiment can be carried out through the following seven methods: the color of HDPE Double wall winding pipe requires that the internal and external layers of the pipe should be uniform and common, and the outer layer is generally black. Other colors can be determined by the supplier and the supplier, and the colors can be planned by the manufacturer. The common inner wall colors are blue, black and yellow. The appearance of HDPE Double wall corrugated pipe the inner and outer wall of HDPE Double wall winding pipe is not allowed to have bubble, depression, obvious impurity and irregular ripple.
管材的两头应平坦、与轴线笔直并坐落波谷区。管材波谷区内外壁应严密熔接,不该呈现脱开现象。小均匀内径 Pe双壁波纹管内径应在答应的范围内,不能够过大,差错为2-3mm,如DN300pe双壁波纹管小均匀内径为298mm,则为合格。
The two ends of the pipe should be flat, straight with the axis and located in the trough area. The inner and outer walls of the trough area of the pipe should be welded tightly and should not be separated. The inner diameter of PE double wall corrugated pipe with small uniform inner diameter should be within the allowable range and should not be too large. The error is 2-3mm. If the small uniform inner diameter of dn300pe double wall corrugated pipe is 298mm, it is qualified.

环刚度 HDPE双壁缠绕管环刚度是一个非常重要的目标,一般客户购买时都是直接问环刚度是多少,双壁缠绕管分SN4和SN8两种环刚度,非标产品一般达不到环刚度要求,如环刚度为8的双壁缠绕管,非标的一般为5-7左右,规范的环刚度则≥4、≥8,这样才算合格。
Ring stiffness HDPE Double wall winding pipe ring stiffness is a very important goal. Customers usually ask directly what the ring stiffness is when purchasing. The double wall winding pipe is divided into Sn4 and SN8 ring stiffness, and the non-standard products generally fail to meet the ring stiffness requirements. For example, the non-standard double wall winding pipe with ring stiffness of 8 is generally about 5-7, while the standard ring stiffness is ≥ 4 and ≥ 8.
冲击功能 冲击功能实验应为TIR≤10百分之。环柔性 要求试样油滑,无反向曲折,无决裂,两壁无脱开,这样则为合格。烘箱实验 在做烘箱实验的时分,应无气泡,无分层,无开裂的状况,这种才算合格的产品。
The impact function impact function test shall be TIR ≤ 10%. The flexibility of the ring requires that the sample should be oil smooth, no reverse twists and turns, no cracking, and no separation of the two walls. In the oven test, there should be no bubble, no delamination and no cracking during the oven test, which is the qualified product.
