Who knows the characteristic of stainless steel PP-R pipe (PPR stainless steel composite pipe)? Thank you
PPR tube interface using hot-melt technology, the tube is completely fused together, so once the installation of pressure test passed, will never leak again, reliability is extremely high. But this is not to say that there is no defect of PPR pipe pipe, high temperature resistance, pressure resistance slightly less working temperature for a long time can not exceed 70 DEG C; the length of each section is limited, and can not bend pipe laying construction, if the long distance or the corner, would be used in the construction of large pipe joints; but cheap the relatively high price of accessories. From the comprehensive performance point of view, PPR pipe is the higher cost performance of the pipe, so it becomes the preferred material for water improvement of home improvement.
PPR pipe diameter can be from 16mm to 160mm, home improvement is used mainly 20mm, 25mm two (commonly known as 6 in charge, 1 inch tube), of which 4 points for the more effective. The diameter of PP-R pipe is outside diameter.
There are three main types of PPR tubes on sale: white, green, and gray. Why is this difference? The distributor's answer is that the raw materials, PPR particles, and fillers are different. Among them, the white and green as the material, better quality PPR tube, gray is the early material is slightly worse than the ordinary tube.
PP-R is officially known as the PP-R pipe, also called type three polypropylene pipe, has the characteristics of light weight, corrosion resistance, no scaling, long service life, is currently the home improvement projects with a water supply pipe up.
It should be said that is lined with stainless steel PP-R composite pipe, which is the same as stainless steel lined composite steel pipe pipes model, with 304 GB stainless steel liner (also according to the purpose and requirement of customers by 316 and 316L stainless steel liner), compounded by a special process. Considering and overcoming the advantages and disadvantages of the two materials, the utility model has the advantages of corrosion resistance, long service life, high cost performance and the like.
