Press Coupling Manufacturers

Ningbo Sunplast Pipe Co., Ltd has been focusing on manufacturing of plastic piping systems for more than 15 years. We started the business as a micro factory which had less 5 workers & only one extrusion line for 20-315mm HDPE pipe, but now, we have been growing to be a modern international factory owning three manufacturing workshops & more than 200 workers. Equipped with world advanced pipe extrusion lines and injection machines, the company’s annual output of plastics reaches over 15000 tons.

Pressure is an essential parameter of the PPR pipe system, but pressure often has many names. If you don't know enough and the concept is not clear, you will often confuse them and can't understand them well.
