In the sewage renovation project of the bus factory area of Jinan Long-distance Bus Station, the underground sewage pipes of this project use HDPE double-wall corrugated pipes and PE water supply pipes. Various specifications from dn300 to dn800 are laid. Dingrun PE drainage and sewage pipes have been used in this project for a long time. Up to thousands of meters, the product is cost-effective!

This project has problems such as poor drainage of the original underground sewage pipes, rainwater seeping directly into the ground, corrosion and damage to the road structure. It is urgent to transform the underground drainage and sewage system. Dingrun's HDPE double-wall corrugated pipes are widely used by the winning bidder. In the sewage renovation of this road, the unique pipe wall structure design greatly reduces the cost of renovation compared with pipes of other structures.

The drainage work of this project adopts a rainwater and sewage diversion system, and the pipes adopt HDPE double-wall corrugated pipes and socket connection methods. The underground large-diameter drainage pipes produced by Dingrun are of high quality and have sufficient inventory. After the winning bidder came to the factory for an on-site inspection, 7 corrugated pipe production lines and 150 acres of stock yard were supplied on the same day.

In the Xincai road pipe network project in Zhumadian, the winning bidder purchased Dingrun's PE water supply pipes and HDPE double-wall sewage corrugated pipes as water supply and drainage pipes in this road pipe network project. Because HDPE plastic pipes are convenient and reliable to connect, a large number of It can replace concrete pipes and cast iron pipes and is easy to construct, which can reduce construction costs and shorten the construction period. Dingrun's products are being used in more and more pipe network reconstruction projects.

This project is a drainage project for a resettlement house in a real estate in Zhengzhou. It is mainly used for daily sewage discharge and rainwater discharge. This project uses Dingrun HDPE double-wall corrugated pipes and plastic inspection wells. The engineering construction is not difficult and the installation is quick. The use of hdpe double-wall corrugated pipes is particularly popular in residential streets. Living communities generally do not cause road pressure. The ring stiffness of the hdpe double-walled corrugated pipes used is sufficient to cope with it. At the same time, it is also suitable for domestic drainage. , the pipeline also has good performance in corrosion resistance and chemical resistance, and its service life can be as long as more than 50 years. The HDPE double-wall corrugated pipes produced by Dingrun are widely used in municipal projects and used as buried rainwater and sewage pipes. This product is widely used in municipal road drainage projects.

Rural sewage treatment projects, referred to as "agricultural pollution projects". The complex terrain in rural areas, mountains and hills, dense river networks, and narrow roads bring great difficulties to construction, and the collection rate will be reduced, resulting in less obvious sewage treatment effects.

In this project, the underground sewage pipe uses the currently commonly used HDPE double-wall corrugated pipe. The double-wall corrugated pipe produced by Shandong Dingrun has been recognized by the local engineering construction company due to its excellent performance. Shandong Dingrun has made improvements in order to improve We provide high-quality products for drinking water source safety issues, sewage treatment and other issues.

Shandong Dingrun's PE water supply pipes, PVC water supply pipes, PVC drainage pipes and other products have been selected into the list of building materials used in various projects of the Runyang Yangtze River Bridge. This project uses PE water supply pipes, PVC water supply pipes, and PVC drainage pipes produced by our company, which are mainly used for water supply and water supply systems. Dingrun PE water supply pipes are produced using imported PE100 or PE80 as raw materials. The hygienic performance complies with the GB/T 17219 standard and the relevant health and safety evaluation regulations of the Ministry of Health. It has good flexibility, strong corrosion resistance, light weight and impact resistance. Excellent characteristics. Products are mainly used in municipal water supply systems, building water supply systems, residential areas, factory buried water supply systems, industrial and water treatment pipeline systems, etc. Lesso PVC drainage pipe is a series of drainage pipe products with mature technology and has been widely used at home and abroad. The product has the advantages of long service life, corrosion resistance, etc. In terms of construction, it is also light in weight, easy to transport and install, and easy to connect. It is widely used in civil building drainage and sewage, chemical drainage and sewage, rainwater drainage and other fields.

The "Bridge Green Belt" project uses PVC water supply pipes produced by our company, which are mainly used for greening irrigation. As a mature water supply pipe, the PVC water supply pipe produced by Shandong Dingrun has acid resistance, alkali resistance, strong corrosion resistance, good pressure resistance, high strength, light weight, low price, small fluid resistance, and no secondary pollution. , meets health requirements, has superior performance such as convenient construction and operation. 

The products are mainly used in indoor water supply and gray water systems of civil buildings and industrial buildings; underground water supply systems in residential areas and factories; urban water supply pipeline systems; water treatment pipeline systems in water treatment plants; marine aquaculture; garden irrigation, well digging and other projects .
