Do you remember the tap water pipe at home when you were a child? In order to increase production and income, they are all cast iron drainage pipes. The disadvantage of this kind of water pipe is that it will rust after long use, so it is gradually replaced by today's aluminum-plastic composite pipe. So what brands of aluminum-plastic composite pipes are there? What is the use of aluminum-plastic composite pipe? How to identify the quality of aluminum-plastic composite pipe? We will explain it for you.

What are the brands of aluminum-plastic composite pipe?

1. lanling aluminum-plastic composite pipe

Shanghai Lanling Pipe Technology Co., Ltd. is headquartered in Shanghai's financial industry. At present, the enterprise has seven production industrial bases and marketing networks all over the country in Fengxian, Jiaxing, Zhejiang, Quanzhou, Fujian, Xuchang, Henan, Linyi, Tianjin and Chengdu, Sichuan. These production bases and marketing networks are strategically distributed all over China, and they can provide customers with equipment and meticulous services immediately.

2. Fixed aluminum-plastic composite pipe

Suzhou Gudao Pipe Technology Co., Ltd. is a pioneering and innovative aluminum-plastic composite pipe company, located in Suzhou, the economically developed Yangtze River Delta region. Is a modern new company integrating product research and development, manufacturing, marketing and service projects. Since its establishment, the innovative development in the pipeline field is people-oriented, and the overall goal is to mold and market the first-class aluminum-plastic composite pipe products in China. Keep pace with the times, and carefully build and shape the first-class hot and cold water PP-R pipe, PVC-U electric welding machine waterproof casing, PVC-U drainage pipe and other product series.

3. Fuyi aluminum-plastic composite pipe

Since its establishment, Zhejiang Fuyi Pipe Industry Co., Ltd. has been focusing on the research, analysis and development trend of low-carbon environmental protection engineering industry. Enterprises adhere to the core concept of "healthy life, I will create". The specific equipment of the enterprise includes: seamless splicing (ultrasonic welding)? Aluminum-plastic composite pipes, RPAP5 pipes and fittings, PP-R pipes and fittings, FR_PP-R glass fiber reinforced pipes and fittings, nanotechnology antibacterial PP-R pipes and fittings, PB pipes and fittings, PE-RT/PEX-a/PEX-b heating pipes and solar pipes, PVC-U drainage pipes, pipes and fittings, PE pipes and fittings, and floor heating water separators.

What is the use of aluminum-plastic composite pipe?

Ppr pipes can be divided into general domestic water pipes, heat-resistant pipes and natural gas pipes according to their uses:

1. Aluminum-plastic composite pipe for general domestic water: ivory L logo, application fields: organic chemical liquid pipes such as drinking water, condensed water, O2 and air compression.

2. Heat-resistant aluminum-plastic composite pipe: bright red R logo, mainly used for long-term working water temperature of 95℃ for boiling water and heating pipeline system software.

3. Aluminum-plastic composite pipe for natural gas: light yellow Q logo, mainly used for transportation, liquefied petroleum gas and liquefied petroleum gas pipeline system software.

4, pipeline engineering construction, must conform to the corresponding technical specifications.

Ppr tubes are widely used in the outer packaging of whitening toothpaste, apple sauce, color paste, shoe polish, food, adhesive, milk, apple sauce, edible spices, skin care products, adhesive, shoe polish, color paste and hair dye paste.

Be sure to pay attention to the price difference of ppr pipes with different prices and different wall thicknesses. Generally, the market price of commonly used ppr pipes with a diameter of 20mm is around 18 yuan, while the market price of pipes with a diameter of 3.2Mm is nearly 1 times more expensive. Thin-walled pipes are much better in heat preservation characteristics, impact resistance and aging resistance, but the price is also much more expensive.

How to identify the quality of aluminum-plastic composite pipe

1, check the appearance of goods:

High-quality aluminum wire mesh skeleton, smooth surface, clearly marked with trademark logo, specifications, applicable environmental temperature and instruments on the wall thickness. The manufacturer also prints the manufacturing serial number on the pipe diameter to supervise the product quality anytime and anywhere. The product packaging is exquisite, and all kinds of signs on the packaging are equally clear. The manufacturer's name, detailed address and mobile phone are all packaged and printed in a prominent position. Fake and shoddy goods generally have unsmooth surfaces, unclear or incomplete marks, simple outer packaging and unknown origin or mobile phone.

2, aluminum layer can not be ignored:

A good aluminum-plastic composite pipe has electric welding at the lap joint of aluminum layer reinforcement, and the aluminum layer and plastic layer are closely combined without delamination. However, the aluminum layers of some fake and inferior commodities are not welded by electric welding, and some aluminum layers and plastic layers are often layered and not tight.
