12 Inch Hdpe Pipe Manufacturer in China

‌12-inch HDPE pipe is a plastic pipe made of high-density polyethylene (HDPE) resin through extrusion molding process. Its nominal diameter is about 305 mm (1 inch is about 25.4 mm). It has excellent impact resistance and environmental stress cracking resistance, and has the advantages of light weight, smooth inner wall, and low water flow resistance. 12-inch HDPE pipe is easy to transport and install due to its good flexibility and welding performance.

Key Features of HUALIN 12 Inch Hdpe Pipe

The 12 inch HDPE pipe has a high density and high crystallinity, which gives the pipe excellent corrosion resistance. It can withstand the erosion of acids, alkalis, salts and various chemical media for a long time, effectively extending its service life. In terms of physical properties, it has both high strength and high toughness, and can withstand greater external pressure and impact. It is not easy to break even if it encounters geological subsidence or external force. The inner wall of the pipe is smooth and flat, with low surface roughness, which greatly reduces the fluid transportation resistance, improves transmission efficiency and saves energy. It also has excellent weather resistance and can maintain stable performance in the temperature range of -60℃ to 60℃. It has excellent UV resistance and aging resistance, can adapt to complex and changeable natural environments, and provide reliable protection for various projects.

12 Inch Hdpe Pipe Considerations

When using 12 inch HDPE pipes, before construction, the SDR (standard dimension ratio), ring stiffness and other parameters of the pipes should be carefully checked according to the project pressure level requirements to ensure that the performance of the pipes is suitable for the use scenario; when storing, the pipes need to be placed in a ventilated and cool place to avoid direct sunlight and high temperature environment to prevent accelerated aging, and it is strictly forbidden to mix with sharp objects or heavy equipment to prevent damage to the pipe surface. During the installation process, hot melt or electric fusion welding must strictly control the temperature, time and pressure parameters to ensure that the interface is completely fused; when laying the pipe, the bottom of the groove needs to be flat and compacted to avoid damage to the pipe by stones, debris, etc., and the expansion joints should be reasonably set to cope with thermal expansion and contraction caused by temperature changes.

HUALIN 12 Inch Hdpe Pipe Applications Explored

In municipal water supply and drainage projects, 12 inch HDPE pipes are used as trunk water supply pipelines to carry large amounts of water, ensuring water quality safety with their corrosion resistance. They can also serve as rainwater and sewage discharge pipes and cope with the erosion of complex fluid media. In the field of agricultural irrigation, their large diameter and low resistance characteristics enable efficient water delivery, helping to stabilize the operation of sprinkler and drip irrigation systems in large areas of farmland. In addition, in communications and power projects, 12-inch HDPE pipes are used as cable protection sleeves. With their high strength and impact resistance, they provide reliable protection for underground communication optical cables and power cables. They are particularly suitable for trenchless directional drilling construction to reduce damage to the ground environment. At the same time, in industrial scenarios such as chemical material transportation and mine tailings discharge, they also rely on their excellent chemical resistance and wear resistance to ensure stable transportation under complex working conditions.

FAQ

How to choose the right polyethylene pipe?

一、Clarify basic parameters
‌1.Material grade selection‌
PE80‌: Suitable for medium and low pressure scenarios (gas, water supply), cost-effective25
‌PE100‌: Higher strength (minimum required strength 10MPa), suitable for high pressure gas or long distance water delivery27
2‌.Temperature and pressure adaptation‌
Ordinary PE pipes have a temperature range of -20℃~60℃, and high temperature scenarios (such as floor heating) require PEX cross-linked polyethylene pipes with a temperature resistance of 110℃78
Choose wall thickness according to working pressure: low-density PE pipe (0.2-0.6MPa), high-density PE pipe (1.0 -1.6MPa)7
二、Scenario-based selection
‌1.Municipal and civil engineering‌
Drinking water pipes: Select HDPE pipes that meet sanitary standards (metal ions <0.1ppb), and give priority to hot-melt connections56
Gas pipelines: Must use black special PE100 pipes, SDR11 thick-walled pipes are suitable for high-pressure sections25
2‌.Industry and special scenarios‌
Mining/chemical industry: Prioritize UHMWPE pipes (better wear resistance than metal), or strong acid-resistant PFA corrugated pipes17
Power protection: Choose ordinary PE pipes for low-voltage cable threading, and choose MPP pipes with stronger pressure resistance for complex geology
