Product description

High temperature polyethylene (PE-RT) is a polyethylene material modified by copolymerization with octene. It is a kind of medium density polyethylene produced by special molecular design and synthesis process. It obtains a unique molecular structure by controlling the number and distribution of side chain octene, thereby improving the heat resistance of polyethylene. Due to the existence of the short octene chain, the macromolecules of PE cannot be crystallized in one lamellae, but run through several crystals, forming a connection between the crystals. This physical connection makes the PE-RT material at the melting point. The following not only retains good flexibility, but also improves its long-term hydrostatic resistance. PE-RT pipe special materials are currently only produced by Dow in the United States and SK in South Korea. At present, all of them have passed the demonstration in accordance with the requirements of ISO10508 and are qualified hot and cold water pipe materials.

Qingdao Longchangjie Machinery Co., Ltd. adopts the technology of Cincinnati, Austria, and designs and manufactures the optimized production line, and adopts the specially produced PE-RT pipe material In addition to the general PE-RT pipe's flexibility and ease of construction, low temperature impact resistance, relatively good thermal conductivity, good recyclability and environmental protection, and hot melt connection, it also has the following characteristics: 


1. The optimized feedback feeding extrusion system is adopted, and the wall thickness is uniform in both vertical and horizontal directions.

2. The production speed is fast, more than 20 meters per minute, and the residence time in the barrel is short, so the aging resistance is better

3. Using a unique water-lubricated sizing sleeve, the surface of the pipe is smooth

4, meter production, can be produced according to customer needs.


PP-R\PE-RT\PB series plastic pipe production lines are mainly used in the production of agricultural water supply, building water supply, central heating system, solar water heating system and so on. The unit consists of a main extruder, a high-pressure head body, a vacuum setting table, a high-speed tractor, a chipless cutting machine, and a double-station coil machine. The single-screw extruder and traction machine adopt imported frequency conversion speed regulation device, and the vacuum pump and traction motor are all high-quality products.


The similar production lines designed and manufactured by Qingdao Longchangjie Machinery Co., Ltd. can replace some of the molds to produce PP, PE, ABS, PPR, PE-RT, PB\silicon core pipes and other materials and pipes. Adopting the extrusion process of the pipe head that draws on the Austrian Cincinnati technology, the plasticizing effect is good, the extrusion speed is fast, the surface finish of the pipe is high, and the product production speed is fast! It has the advantages of convenient operation and reliable performance, reaching the international leading level.
