I’m asking which expert has a grade table for non-metallic pipe materials

You’ll be disappointed if you watch it; there’s very little content, and most of it is about MFRS

I’m not picky; it’s fine to have something to refer to. The main issue is that I don’t know how to start making a choice right now.

Manufacturer standard; all non-metallic items follow the manufacturer’s standards.

Create your own designation; for example, FRPP. The current standard is HG 20539-1992 \"Reinforced Polypropylene (FRPP) Pipes and Fittings\", which includes the PN6 and PN10 grades – simply copy in the corresponding wall thickness values. The problem is that the standards are outdated; for pipe diameters not listed therein, it is necessary to consult the manufacturer.

The wall thickness is fine – those can be found – but it’s not easy to come by the corresponding pipe fittings and valves.

Are pipe fittings and valves also part of the matching set?

Give me an email address, I’ll send it to you. It’s not easy to upload directly

Please specify the working conditions and materials, etc

Polycarboxylate semi-finished products, sodium gluconate aqueous solutions, as well as some wastewater; the materials primarily used are PP, PPR, and FRP. Email: 610193126@qq.com. Thanks, haha~

Are you in design or procurement? Has the pipe specification been determined? The general process is as follows: first, determine the temperature, medium, design pressure, and stress. Then, based on the mass flow rate, average flow velocity, and fluid density under actual operating conditions, the inner diameter of the pipe is determined, and the pressure drop is calculated. Determine the design pressure, and calculate pipe series S using the design pressure and design stress. By determining the material using pressure, temperature, and medium as three key factors, and by consulting relevant standards to clarify the specifications and pipe series, you can obtain the specific parameters of the pipe you need. Then consult plastic pipe and valve manufacturers; some large companies that have the capability to produce both pipes and valves will provide you with what you need. Regarding valve types, ball valves are commonly used for small-diameter pipes, while butterfly valves are preferred for large-diameter pipes. Diaphragm valves are the best choice when flow regulation is required or high efficiency is needed. Many times, if you don’t want to go through a design institute, there are simpler ways: you can simply use existing experience-based materials and specifications
