Scope

Main Technical Content: 6. Technical Requirements 6.1 The colors of the inner and outer layers of the color pipe should be uniform. The outer layer is generally orange, and other colors can be agreed upon by the supplier and buyer. 6.2 The appearance of the pipe should not have bubbles, indentations, obvious impurities, or irregular wave patterns on the inner and outer walls. The two ends of the pipe should be flat, perpendicular to the axis, and located in the trough area. The inner and outer walls of the pipe in the trough area should be integrally molded and tightly welded, without any delamination or separation. 6.3 Specifications and Dimensions The pipe dimensions are expressed in nominal inner diameter (DN inner diameter series). 6.3.1 Length The effective length of the pipe L is generally 6m, and other lengths can be determined by the supplier and buyer through negotiation. There should be no negative deviation in length. 6.3.2 Dimensions The dimensions should meet the requirements of Table 3, and the distance S between the cutting surfaces of two sections of pipe after being connected by clamps should be less than or equal to the data specified in the table. For example, for an outer hexagonal inner-diameter pipe with a specification of ID200, S≤5.
