recent years, with the continuous growth of the demand for PE coils in the fields of municipal engineering, rural drinking water safety, construction water supply and drainage, etc., the market scale is expanding, and the competition is becoming more and more fierce. Many brands have launched price wars to seize share, sacrificing quality to choose recycled materials and simplifying production processes have occurred from time to time, resulting in "low price and low quality" becoming a lingering worry in the industry. In such an environment, AD Pipe has become a "fixed choice" for many customers with "always stable quality".

"We choose AD PE coil, and the picture is'worry-free '." At the site of a municipal road rain and sewage diversion project in Jiangsu, Manager Li, who is responsible for material procurement, expressed the voices of many customers. Previously, the project had tried other brands of PE coils. During the construction, it was found that the wall thickness of some pipes was uneven, and there was leakage during the pressure test, which not only delayed the construction period, but also increased additional costs. After switching to AD PE coils, the sampling results of three consecutive batches of goods met or even exceeded the national standards, and there was no quality problem during the construction process. "Now as long as we use PE coils for our project, the first reaction is to find AD."

This "worry-free" comes from AD Pipeline's full chain control of quality. In the raw material link, AD always insists on using high-quality polyethylene resins from well-known manufacturers such as Yanshan Petrochemical and Qilu Petrochemical, and refuses to mix any recycled materials or inferior materials - "Raw materials are the'cornerstone 'of the pipeline, cutting corners will only smash their own signboard." Chen Gong, head of AD's PE coil production line, introduced that each batch of raw materials must be tested by infrared spectroscopy to ensure that the molecular weight distribution, density and other indicators meet the requirements.

Precise control of the production process is the key to stable quality. AD has introduced twin-screw extrusion equipment imported from Germany, and adopts a full-process automatic control system to monitor 12 key parameters such as extrusion temperature, screw speed and traction speed in real time, and the error is controlled within 1 ° C. " In the past, manual adjustment was inevitable, but now machines are more'serious' than people, and the wall thickness difference of each meter of pipeline does not exceed 0.1 mm. "Chen Gong pointed to the parameter curve on the computer screen and said.

is more" serious "about quality inspection. AD has established a" full batch, full project "testing system: each batch of PE coil must be tested for 8 core indicators such as hydrostatic strength, resistance to environmental stress cracking, and melt mass flow rate. It even simulates the low temperature environment of minus 20 ° C for impact tests to ensure that the pipeline can maintain stable performance under extreme conditions." Although the impact resistance of a batch of products last year reached the national standard, it was still 0.5 joules short of our enterprise standard. We directly did scrap treatment. " The head of the quality department of AD said, "What customers want is'always easy to use ', not'just qualified'."

this "will not be" insistence, in exchange for long-term trust of customers. In a rural drinking water safety project in Zhejiang, AD PE coil was buried underground for 5 years, experienced high temperatures of 40 ° C in summer and minus 5 ° C in winter, and never leaked or cracked; in an orchard irrigation project in Guangdong, due to a small amount of acidic substances in the water quality, other brands of pipes were corroded and thinned after one year, while AD PE coil used for three years and still maintained good corrosion resistance.

"No matter how fierce the competition is, the customer finally chooses'rest assured '." "We don't fight price wars, but spend costs on raw materials, equipment and quality inspection - because we know that a pipe that can run stably for 10 years is more valuable to customers than a pipe that is 20% cheaper but breaks down in two years," said the head of the PE coil line of AD Pipeline.

In this "fast-paced" market, AD Pipeline uses "slow work" to polish quality: there is no gorgeous marketing slogan, only seriousness to each pipe; there is no short-term benefit calculation, only long-term response to customer needs. And this "stability" is the reason why customers are willing to choose AD again and again - after all, for pipelines that need long-term operation, "reliable" is more important than anything else.
