The structure of Antong PP-R aluminum-plastic composite pipe is: outer layer PP-R, intermediate welded aluminum layer as skeleton, inner layer of cross-linked polyethylene (or polyethylene), PP-R and aluminum layer, cross-linked polyethylene The aluminum layer is bonded with a special hot melt adhesive, and the five layers are co-extruded.

Features:

A, the perfect combination of plastic and metal, so that it has the flexibility of the plastic tube and the rigidity of the metal tube, can bend without rebound. B. PP-R pipe fittings are used during installation, hot-melt connection, never leaking, and low engineering cost. C, the coefficient of thermal expansion is small, far lower than PP-R, close to the metal tube, no deformation when exposed to heat. D, the inner layer is made of cross-linked polyethylene, high temperature resistance, working temperature up to 95 °C. E. The middle layer is made of high-precision alloy aluminum, which not only increases the strength of the pipe but also enhances the oxidation resistance, keeps the water quality inside the pipe from being oxidized, and ensures the cleanliness of the water source.

Scope of application:

PP-R aluminum-plastic composite pipe, mainly used in the transportation of hot and cold water in industrial and civil buildings, heating, solar energy, central air conditioning, floor radiant heating, refrigeration, food and beverage, chemical and other pipeline systems. Especially for heating pipes, it has a unique advantage.

Comparison of various pipe properties:

Antong Management reminds you to pay attention to:

A. The use of Antong brand pipe should prevent the solid phase transformation (liquid becomes solid) in the pipe from damage to the pipeline, and protective measures must be taken.

B. In the environment with low temperature (below 5 'c), the PP-R pipe has certain brittleness, and it is strictly forbidden to throw or knock during transportation or use.

c. When installing PP-R aluminum-plastic composite pipe, special attention should be paid to the use of reamer to round the pipe welding interface before welding. When welding, the pipe and pipe fittings must be aligned in parallel and cannot be welded. To avoid leakage.

Yinan County Xinxing Pipe Industry Co., Ltd. is located in Weinan County. The company has a registered capital of 3.9 million yuan and covers an area of 21,520 square meters, including a construction area of 14,962 square meters. It has 188 employees, including 34 professional and technical personnel, and has excellent production and R&D teams. It has fixed assets of 30 million yuan and an annual output value of 110 million yuan. It is a member of Shandong Construction Science and Technology Association.

In recent years, with the promotion and application of China's plastic building materials, the plastic pipe industry has developed by leaps and bounds. Our company has developed new water supply and heating pipes such as PP-R pipe, PP-R aluminum-plastic composite pipe and PE-RT floor heating pipe. The company now has ten polypropylene (PP-R) pipe production lines for hot and cold water, three PP-R aluminum-plastic composite pipe production lines, three PE-RT pipe production lines and eight tube injection molding machines. It can produce 25 million meters of PP-R pipe, 6 million meters of PP-R aluminum-plastic composite pipe, 10 million meters of PR-RT pipe and 500 tons of pipe fittings. In 2012, the company added five new PVC-U drainage pipe production lines, four insulated and flame-retardant electrical casing production lines and five pipe injection molding machines to produce PVC-U solid wall drainage pipes, pipe fittings, hollow spiral drainage pipes and electrical casings. At this point, "Antong" brand products have covered the construction of water supply and drainage, floor heating, electrical casing and other piping systems.
