According to the U.S. Advanced Materials Information (AMI) survey, the current European transport hot and cold water pipes for a total length of 1.6 billion m, of which half, or 777 million m of plastic pipe. In 2008 as a whole is expected to hot and cold water pipes in the market growth rate will reach 0.9%, while the share of plastic pipe are expected to increase 4.1%. Plastic pipes conveying hot water mainly applied to geothermal energy facilities, heating facilities and drinking water pipelines and other fields. Because of its obvious advantages, plastic pipe used in the share of modern geothermal systems account for 96% of the overall market share. Which, PEX pipes are widely used, accounting for about 70%. In contrast, steel and copper is still the heating and sanitary pipelines main materials, accounting for about 60% of the overall market share. Synthetic materials and PEX plastic pipe for the main raw material. By 2008, the U.S. intelligence agencies Advanced Materials (AMI) composite pipe is expected to reach the highest growth rate of 8.4%, PE-RT pipe will grow 4.8%, PEX pipe will grow 2.9%. At the same time, market researchers forecast the market share of steel pipe will reduce by 1.6%, copper will be reduced 4%.

Equipment suppliers of raw materials on the challenge of

Production of hot water pipe diameter range is generally 12 ~ 63mm, the most commonly used for the outer diameter 16mm and 20mm, wall thickness from 2mm to 3.5mm hot water pipes. Depending on the application different manufacturers should first be clear that not all plastic raw materials to produce the pipe are also applicable to the delivery of drinking water. For example, PEX-a and PEX-b does not apply to drinking water, transport, and PEX-c are fit. In addition to various types of cross-linked PE, such as PE-RT, etc., PP-R, PB, C-PVC raw materials and aluminum-plastic composite materials are also widely used. Drinking water pipes mainly include PE-RT, C-PVC and PEX-c, different types of PEX-a and PEX-b are used for geothermal and heating systems. To meet the pipe manufacturer to product the same time, low-cost, high quality requirements of raw materials must be different for each pipe extrusion production line for reasonable adjustments.

A variety of devices to meet the diverse needs of

Cincinnati Extrusion Technology Co., Ltd. in the field of plastics processing machinery and the structure of extruder screw has decades of experience. For example, whether it is carried out for different types of PEX, or cross-linked processing of aluminum-plastic composite materials for the overlap, both producing multi-layer tube or single-tube, extruder from Vienna, Austria, according to customer demand experts are able to provide the most the ideal model and the best production and processing technology. Monos high-performance single-screw extruder series of its processing length of 37D, so compared to traditional extruder under the low melting temperature may be increased by 30% of its production, especially for PE-RT or PP-R pipe high-performance extrusion. Universal Extruder Talos series can also be used in PE-RT, and PP-R pipe extrusion, but more suitable for processing of different types of PEX. Standard Alpha extruder or co-extruded with relatively simple model not only has a clear price advantage, but also can be used for thin-walled tube, multi-link layer or adhesive tube extrusion color.

From the extruder to the volume control machine

In addition to the existing plastics unit, the Cincinnati IRIS product range covers a series of single-layer tubes as an option for co-extrusion dies and molds, up to three layers of the multi-layer pipe molds. VKS-AW sizing unit to ensure that even in large pipe wall thickness of pipe production, so as to maintain the ideal geometry. For the maximum diameter of 32mm high-performance out of a small pipe run, Cincinnati Extrusion Technology infiltration of water tanks is recommended to ensure the stability of an integrated cooling production.

Diameter up to 63mm for the large-diameter pipe production, cooling water tank immersion can be applied using either spray-type.
Depending on the application is different from the cooling device can connect after the drying device can also be connected with the crosshead of the preheating unit. For example, in aluminum-plastic composite pipe or through a two-step treatment with a layer of EVOH Oxygen-pipe production, to improve pipe quality standards, the company used a new type of contact with the surface of the extension RAE63 / E tube traction device. Finally, at the end of each pipe extrusion line equipped with semi-automatic or fully automatic volume control machine
