L1G plastic pipes: diameter, wall thickness, and wall thickness compared to standard metal pipes
Thread Content
I’d like to ask for some advice. For example, for a metal pipe with DN50, the outer diameter and wall thickness are Φ57×3.5. What is the wall thickness of an L1G pipe with DN50? Also, regarding plastic threaded pipes, what is the best way to connect them to equipment interfaces or flanges? Thank you, everyone
What kind of pipeline is the L1G pipeline? ? ?
1.0MPA reinforced polypropylene pipe
I’m not sure about the non-metallic pipe series – aren’t there any design manuals or specifications? ?
It depends on what your pipeline standards are
The applicable standard will do, as the standard I checked does not match the outer diameter of the metal pipe
HG 20539-1992: Reinforced polypropylene (FRPP) pipes and fittings; for pipe sizes DN50, the dimensions are D60X6, with only threaded fittings available; flanges are used for sizes DN65 and above.
Thank you. This is exactly what I was looking for. For example, if its outer diameter is 60 and the wall thickness is 6, how can it be connected to the pipe outlet of the equipment?
HG20592 features a threaded flange that can connect plastic pipes with threaded ends to equipment ports with flanges.
1. Pipe grade L1G: L-PN10 – 1 is the sequence number; G denotes non-metallic pipes, indicating the pipe grade. 2. For non-metallic pipes, the wall thickness is generally not specified; instead, material standards from the PN series are chosen based on the temperature limits of the material, such as PN16.
