Introduction

includes PVC pipes and fittings. With excellent properties, it is a perfect solution for water drainage in residential, commercial, and industrial sectors.

However, materials like iron pipes, copper pipes, stainless pipes, and many other materials can also be used for drainage. Why should you choose PVC pipes for drainage? How to choose appropriate PVC pipes for your projects? Let’s check the answers in the following parts.

What is PVC Drainage Pipes?

PVC drainage pipes are made of polyvinyl chloride resins that the third most widely utilized synthetic plastic polymer?in the world. Compared with other materials, PVC pipes are more economical and lightweight for easy transportation and installation. They feature relatively excellent tensile strength, stable chemical performance, good oxygen index, and a high flame retardancy rating. Hence, it is an ideal material for drainage.

How to Choose a Better PVC Drainage Systems for Projects?

RIFENG PVC Drainage System is a better option for drainage. Compared with many traditional PVC drainage systems, its properties are more outstanding based on innovative techniques.

?#1 Environmentally friendly and safe
EPD /CE certificated: non-toxic, odorless, lead-free, healthy, and environmentally friendly.High flame retardancy rating: can self-extinguish within 30 seconds when leaving flame.

?#2 Superior performance and durability

Pipes: good flexibility and high impact resistance. It can withstand the flat test reaching more than 40% strength without cracking.
Fittings: more durable with better impact resistance.
Powerful sealing performance: outstanding water-proof performance with high-quality adhesive.

?#3 Sophisticated and advancing manufacturing processes

Low coefficient of roughness (0.45): smooth inner walls for faster drainage.
Compared with iron pipes of the same diameter, the drainage efficiency of RIFENG PVC pipes can be increased by 30%.

?#4 Comfortable drainage experience for users

Easy installation: lightweight for easy delivery?and faster installation with glue or rings.
Low noise: a unique spiral structure for great noise reduction
Deodorant: The design of air pressure balance allows for better waterproofness and prevents odor.

Four Types of PVC Pipes You Should Know

PVC?Solid Pipe?
PVC Solid Pipe?is one of the PVC pipes in the RIFENG PVC Drainage System. PVC solid pipes are usually used for double standpipes systems. Their specification covers 32, 40, 50, 75, 90, 110, 125, 160, 200, 250, and 315mm. With high-grade raw materials and outstanding performance, they are cost-effective.

PVC Reinforced Spiral Pipe
RIFENG PVC Spiral Pipes are designed with unique spiral walls. This spiral structure can greatly lower noise. In addition, the spiral edges greatly improve the drainage efficiency of the system. The flow of pipes with diameter nominal (DN) up to 110mm can reach 6L per second. This efficiency is two times that of the general drainage standpipes. Also, the design of air pressure balance allows for better waterproofness and prevents odor.?Currently, the specification of this product equipped with 24 spiral edges is 110mm.
?

PVC Hollow Spiral?Pipe
RIFENG PVC Hollow Spiral Pipe features a double-layer hollow structure. Their inner walls are equipped with 6 spiral edges at least. This structure allows for a better silencing effect, reducing drainage noise by more 10-15dB?than the reinforced spiral pipes. What’s more, their ring stiffness is higher than that of PVC solid pipes. Hence, they are more durable and tougher. This product is also designed as singer standpipes.

What PVC Fittings are Available for PVC Drainage Systems?

RIFENG provides various fittings so that you can build up a complete drainage system. Here are parts of fittings you may be interested in.

Expansion joint

It prevents bending and deformation of pipes caused by expansion and contraction
When the floor height is less than or equal to 4 meters, a standpipe needs?an expansion joint on each floor.
When the floor height is greater than 4 meters, the number of expansion joints should depend on the designed?expansion and contraction of pipes.

Standpipe?cleanout

It is used for cleaning when a?standpipe is blocked by dirt.
Every drainage pipe in?a high-rise building needs?cleanout, and the distance between each one should?be less than 10m.

Standpipe?cleanout

It is used for cleaning when a?standpipe is blocked by dirt.
Every drainage pipe in?a high-rise building needs?cleanout, and the distance between each one should?be less than 10m.

P-trap with a cleanout

It is suitable for sanitary drainage with a cleanout at the bottom.
A?water seal is formed at the bottom to isolate the?upper and lower?moisture and prevent the leakage of odor?during drainage.

Ventilate cap

The roof or corner needs it to improve the ventilation of pipes and prevent the rubbish from falling and blocking the pipe.
