Shandong Yost Economic And Trade Co.Ltd

Model Number: SDY-10-1-#6289 Brand Name: SHIYU Key Specifications/Special Features: PVC-U water pipes and fittingsApplications area:Chemical supply systems engineering, civil, commercial and residential property water supply systems engineeringMunicipal pipe network, public facilities, systems engineeringElectronics, electroplating industry water supply systems engineeringAgriculture, animal husbandry, irrigation and drainage systems engineeringMari-culture systems engineering

Feature and benefits:
1. Lightweight:
Weight in unit length is only 1/6 of the cast-iron pipes
2. High strength:
Tensile strength comes to be more than 45MPa
3. Less resistance:
Inner wall of the PVC-U pipes is very smooth which prevents scum buildup
Water pressure and discharge of PVC-U pipes is 30% lower than cast iron pipes in the same diameter and it can save the cost of discharge power
4. Good corrosion resistance:
Has excellent resistance to the corrosion caused by acid, alkaline, chemical and electricity
Stains will not occur
5. Simple installation:
Connection with rubber ring is very easy, also very easy to carry out and seals well
6. Long lifespan:
Under the normal working pressure, the lifespan will be up to more than 50 years
7. Sanitary and nontoxic:
PVC-U pipes meets the drinking water standard and the water is conveyed without secondary pollution
