Product Features
1. Corrosion resistance
PPR pipes and fittings can resistant to most chemical corrosion; it can withstand PH value range 1-14 high concentration of acid and alkali corrosion over a wide temperature range.
2. Installation performance
PPR pipe PPR pipe is light in weight, and the operation installation is easy, which make it available to weld again. It is very important that pipe and pipe fittings can be welded together in seconds with a simple tool. Compared to traditional connection methods it can save 40%~50% of the time.
3. Safety Indicators
The basic component of PPR is carbon and hydrogen which is simple. It keeps in line with food hygiene regulations, non-toxic. If you use PPR pipe, there will no dirt in the inner wall or “secondary water pollution” caused by rust any more.PPR pipe ,green building materials, is more suitable for transporting drinking water.

Advantages of PPR pipe
1. Maximum operating temperature can up to 95℃; it can work in a long term under the condition of 70℃ and 1.0Mpa.
2. PPR pipe density is only 1/8 of metal pipe; pressure resistance strength test is up 5Mpa, with good toughness, impact resistance.
3. Inner diameter of PPR pipe is little bigger than that of pipe fittings, which can ensure not to increase the resistance to fluid flow.
4. Inner wall of PPR pipe is smooth, no rust, no scaling, small fluid resistance
5. PPR pipe has excellent insulation properties, can significantly reduce the vibration and noise caused by the flow of liquid.
6. PPR pipe energy consumption is only 20% of steel pipe; its thermal coefficient is also only 1/200 of steel pipe, reducing heat loss greatly.
7. PPR pipe is poor electrical conductor material, which can avoid galvanic corrosion phenomena.
8. With poor thermal conductivity, PPR pipe can reduce condensation.
9. PPR pipes, fittings are recyclable.

Construction Installation Guide of PPR Pipe

I. General Provisions
1. Before the pipeline installation and construction, should be with the following conditions:
a Drawings and other technical documents complete, and has been drawing technical tests, meet the construction requirements;
b Construction plan, construction techniques, materials and other equipment to ensure the normal supply of construction;
c Should be applied to the technical training of personnel through building water supply polypropylene pipeline installation.
2. Pipes and fittings provided shall meet the design requirements, along with the product specification and quality certification.
3. Do not use the material for signs of damage. Pipeline quality found abnormalities, should be identified prior to use technology or re-examination.
4. Pipeline system during installation openings should be blocked.
5. The construction should review the installation of cold, hot water pipe pressure rating and usage scenarios. Pipeline markers should be open to the outside, in a prominent position.
Second, the pipeline laying installation points
1. The pipe-wall Concealed, should be set aside with the civil recess dimensioned not specified, in-wall underground pipe wall groove depth De ten sizes 20mm, width of dry De + 40 ~ 60mm. Quiet concave surface must be smooth, without sharp corners and other projections, the pipeline pressure test, the groove wall with cement mortar to fill dense M7.5 class.
2. Pipeline Concealed in the floor surface, according to the design drawing position. As applied to the site there is a change, there should be shown the recording.
3. PPR installation, without axial distortion, when the wall or floor, the correction should not be mandatory. Polypropylene water pipes should be laid in parallel with other metal pipes have some protection from the net distance should be less than 100mm, and it should polypropylene tubes on the inside of the metal pipe.
4. The indoor surface mounted pipeline, should be carried out after the completion of the civil whitewash, the installation should be reserved holes with the civil right or top manager sleeve.
5. The pipe through the floor should be provided with steel casing, the casing above the ground 50mm, and a waterproofing. If the pipeline crosses roofing, waterproofing should be taken strict measures. It should be set through the front-end bracket.
6. When the hot water pipes through the wall, should be set up with civil steel casing, when the cold water pipe through the wall, can be reserved hole, the hole size than the outer diameter of 50mm.
7. Buried in the ground floor surface as well as inside the pipe wall, pressure test should be prepared and hidden works acceptance records for shelter before the closure.
8. Building physics introduction pipe and buried pipe laying indoor requirements are as follows:
a. Indoor floor the following pipeline 0.00 disabilities should be divided in two phases. 0.00 The following persons Floor laying the foundation wall to wall section to be first; after the paternity civil construction, then the outdoor connection pipe laying;
b. Indoor floor the following pipeline should be after the construction backfill compaction, re-excavation carried out. Prohibited in the soil before or without backfill compaction of laying;
c. The laying of the pipeline ditch should be flat; one must highlight the sharp hard object. Soil particle diameter of is not more than 12mm, to 100mm thick sand cushion shop when necessary.
d. When the buried pipeline backfill, backfill pipe circumference shall inclusion sharp hard object from indirect contact with the wall. Backfill soil should be sand or particles of diameter of not more than 12mm to the top of the pipe at the side 300mrn, after compaction before backfill the original soil. Indoor buried pipeline buried depth of not less than 300mnl;
e. Pipeline floor should be set at a protective tube with a height above ground assessment 100mnl;
f. The pipeline through the foundation wall should be provided with a metal sleeve. Casing and foundation wall reserved headroom above the hole, special design not less than 100mm;
g. Pipeline crossing the neighborhood road, when Futuhoudu less than 700mm, should adopt strict protection measures.
