Differences between steel wire welded skeleton reinforced polyethylene composite pipes and steel skeleton polyethylene plastic composite pipes
Thread Content
For the project design currently in progress, the following options are recommended: 1. Polyethylene composite pipes reinforced with a steel wire welding framework; the applicable standard is SY6662.1-2012. I have been exposed to this type of pipe before. 2. Steel-framework polyethylene plastic pipes of a vintage style; the applicable standard is HG/T3690-2012. After discussing this with the designer, it was stated that the first option has higher strength and can withstand greater pressures, while the second option’s pressure resistance does not meet the requirements of our project. I contacted several steel frame manufacturers, and they generally dismissed the former as trying to play it by the rules in a clever way. Dear Haiyou, have you come across these two types of pipes? What are the differences between them?
The manufacturers I can contact at the moment are all those that produce steel-reinforced polyethylene plastic composite pipes, which are the second type of pipe. Manufacturers that have the first type of pipeline can also recommend them to me. I compared the samples of the two types of pipes
If transporting the material poses certain risks, opt for a higher standard rather than a lower one
Buried fire water pipes; I mainly want to know the differences between these two types of pipes
The pressure in fire hoses is relatively high; therefore, welded steel wire-reinforced polyethylene composite pipes are a suitable choice when these pipes are to be buried underground
Well, the current design also uses a steel wire-welded skeleton to reinforce the polyethylene composite pipe
The two are identical; the only difference lies in the reinforcement layer in the middle – some use steel wires for reinforcement, while others use wire meshes. In some cases the wire meshes are not welded together, and in other cases they are. Each manufacturer has its own approach； If possible, find some large manufacturers, provide them with the medium and parameters, and let them make recommendations; this would be a better approach
