Twenty years ago, polypropylene pipes and fittings began to be used in full swing in the water supply industry. The material is cheap, easy to install. Has a long service life.
At the same time, metal-plastic appeared on the shelves. The pipe has many advantages like polypropylene. Delivered in bays, easy to transport. Installation is simple as with polypropylene. But due to the dominance of low-quality pipes from the Middle Kingdom. The authority of this pipe was badly tarnished. Therefore, it was mainly replaced by polypropylene.
And now, just over 15 years have passed, since the beginning of the 2000s, a special trumpet was born. Russian production.
Hello friends, this is a Plumber, Timofey Mikhailov. In this article, I will introduce you to a new pipe on our market. Which recently appeared on our local counters.
It seems that there are already pipes made of various materials: high-pressure polyethylene, low-pressure polyethylene, stainless pipe, copper pipe, iron pipe, polypropylene and metal-plastic, etc. Everything is invented ...
But no. The plant in the city of Chelyabinsk produces an interesting pipe with the properties of polypropylene and metal plastic.
The pipe is supplied as metal plastic in coils. Pay attention to the composition of the pipe, what its layers are made of. The photo clearly shows the abbreviation:
LD FORS PP-R-AL-PP-R This means that the inner layer and the top layer are made of polypropylene. And the middle layer is made of aluminum.
This is clearly visible in the section.
I also made a longitudinal section:
A pipe with such layers allows for diffusion welding using conventional polypropylene fittings.
And also use metal fittings for metal plastic. As usual, this is done.
As a result, it turned out to be a very versatile pipe. It has all the advantages of polypropylene and metal-plastic pipelines. Which is very pleasing. First impressions from working with her are positive:
