May I ask how the insertion depth for the electrofusion joining of perforated steel-reinforced polyethylene composite pipes is determined?
Thread Content
I searched the internet extensively, and what I found was mainly information related to the electrofusion splicing of polyethylene pipelines; there seemed to be a great variety of such content. Most people say to make marks according to the specified socketing depth, but what exactly are these specifications? Some don’t mention it, while others do provide a table. There are also some operation videos that seem to show measuring the depth of the pipe fitting, making a mark on the pipe directly afterwards, and then driving it in until the end. . . I would appreciate it if experienced experts could help clarify this. It would be even better if there are official construction standards; the information I’ve found so far doesn’t seem reliable.
The insertion depth for electrofusion joints usually depends on the dimensions of the fittings and pipes; typically, manufacturers provide a table showing the insertion depths for electrofusion fittings. In actual construction, operations should be carried out in accordance with the information provided by the manufacturer or industry standards. Too shallow an insertion depth may result in a weak connection, while too deep a depth may cause excessive internal stress. It is recommended to consult specific industry standards or manufacturer guidelines to ensure the correctness and safety of electrofusion connections. If there are no clear standards, the internal depth of the fitting can be used for measurement and marking, to ensure that the pipe is inserted in the correct position. .
