Centrifugal cast iron drain pipe is widely used in the world of one of the main material of drainage，Using centrifugal casting，compact texture，thin pipe wall,Light-weight,The interface is made of stainless coupling and rubber sleeve connection,easy to assemble and unassembled.Our company production of cast iron drainage pipe model not only is complete,but also completely meet EN877 / ISO6594 standards.Product use Germany to specify special import paint.Feature:Durable more than expected life span of the buildings; Non-combustible material, don't spread spark, non-toxic; Corrosion resistance, aging; Expansion and contraction coefficient; Low noise; Flexible earthquake, strong tolerance, light weight; Joint seepage and seepage; In the design of the standardization, integration (can be connected with other pipes), beautiful; Easy installation, maintenance, environmental protection can be completely recycled.

This group of cast iron drainage pipe and with grey centrifugal casting, Using electrostatic spraying process（TML）. The process a coating can be thicker coating, coating corrosion resistance performance is very good. Use powder electrostatic spraying process, high efficiency, suitable for automatic coating line, powder utilization ratio is high, the recycled use. With a enhanced whirl cross can make up a special stand-up drainage pipe system.

The feature of the system:

1. Silence

Stand-up water folw and horizontal water flow come into whirl flow by special pipe structure,this design is good to reduce water flow speed,reduce impact between water and pipe wall,so as to reduce the noise.

2. Large Flow Rate

Upper and under connection design which avoid water block,keep air smooth in the pipe,sure the pressure balance in the pipe, is good to improve drainage ability.

3. Cleanliness

Should use floor drain match with the special stand-up pipe.The area rate should>1.

4. Save Energy & Reduce Wastage

No-need Ventilated stand-up pipe,whice is reduce large material and construction cost,also increase using area.
