ERA Piping PPR Fittings Reducing Socket E-Type

ERA Piping Systems, PPR TYPE II Pipe Fitting , REDUCING SOCKET ,PRII004
System: ERA PPR pipes, due to its high impact strengh and light weight makes it most reliable and sophisticated system to be employed in plumbing applictions and water supply(hot and cold).
Scope:
ERA's PPR is the ideal and above all cost-effective solution for piping installations in schools, hospitals, hotels, office blocks as well as in fields of modular construction.
This specification covers PPR pipe and fittings for pressure applications.This system is intended for pressure applications where the operating temperature will not exceed 95 °C.
The integrated system is easy to use and install, fulfills the stringent requirements of the water sector and offers excellent value for money.
System: Good long term pressure resistance and easy processing and installation technique give cold and hot water systems made of PPR pipes an advantage as an alternative to the traditional systems.
PPR systems are available in a wide range of pipes sizes and fittings from 20mm to 63mm.
PP-R is also called three-type polypropylene tube and random copolymerization polypropylene. Random copolymerization polypropylene is extruded into pipe and injection molding into pipe fitting. Polypropylene random copolymer is also a kind of polypropylene. The basic structure of its polymer chain is modified by adding different kinds of monomers. Ethylene is the most commonly used monomer, which causes changes in the physical properties of polypropylene.
2, compared with pp homopolymer, random copolymer improved optical properties (increase transparency and reduce turbidity fog), improve impact resistance, increase flexibility, reduce the melting temperature, thus also reduce the hot melt temperature; At the same time, the properties of chemical stability, water vapor isolation and organosensory properties (low odor and taste) are basically the same as homopolymer. Used in blow molding, injection molding, film and sheet extrusion processing fields, as food packaging materials, pharmaceutical packaging materials and daily consumer goods.
The PP-C pipes on the market are actually PP-B pipes, and their raw materials are special materials for block copolymer polypropylene pipes. PP-B pipe is a type of cold and hot water pipe, which is relatively cheap. Its heat resistance and pressure resistance performance differ greatly from PP-R. For example, the service condition classification is 2, the design pressure is 0.6MPa for DN25mm pipes, the wall thickness of PP-R pipes is 3.5mm, and the wall thickness of PP-B (PP-C) pipes is 5.1mm; The design pressure is 0.8MPa DN25mm, and the wall thickness of PP-R pipe is 4.2mm, while PP-B (PP-C) cannot be used. Because the required wall thickness is too thick, PP-C pipes with the same structural size as PP-R in the market have much lower usage conditions and cannot be mixed with PP-R pipes, let alone replaced with PP-C pipes after determining usage conditions. Use condition 2 indicates a design temperature of 70 °C for heating water.
