Product Specification

                                   Professional  PEX  Pipe Extrusion Machine Line Manufacturer In China

PEX pipe extrusion machine line is used for making different diameters and thickness of PEX pipes , which is used for hot water supply & drain system. PEX tubing is made from cross linked HDPE (high density polyethylene) polymer. The HDPE is melted and continuously extruded into tube. The cross linking of the HDPE is accomplished in one of three different methods.

Cross-linked polyethylene (PEX), a type of flexible plastic, is currently replacing traditional copper and galvanized steel as water supply lines in both new construction and remodeling projects.  PEX (or cross linked polyethylene) is part of a water supply piping system that has several advantages over metal pipe (copper, iron, lead) or rigid plastic pipe (PVC, CPVC, ABS) systems. It is flexible, resistant to scale and chlorine, doesn't corrode or develop pinholes, is faster to install than metal or rigid plastic, and has fewer connections and fitting.

PEX is available in a variety of lengths, from short 10-foot pieces (for small repairs) to rolls over 500 feet long, which are used to install a home’s entire water supply system. PEX pipe ranges from 3/8- to 1-inch in diameter and its color-coding makes it a snap to identify what a specific pipe is used for. Although there are three types of PEX (see Label Lingo, below), the different colors don’t connote the distinctions; they simply make it easy for the installer to identify which lines carry hot water and which carry cold.

• Red PEX pipe carries hot water.

• Blue PEX pipe carries cold water.

• White PEX pipe can be used for either hot or cold water.

• Gray PEX pipe, like white, can be used for either hot or cold water (although not all DIY centers carry gray).

PEX pipe has the following application:

• Cold and hot water system for buildings.
• Air-condition system and sewage treatment system.
• Concentration heating system in the residential houses
• Floor radiant heating system and snow melting system of airport and traffic network.

 Advantage of PEX pipe as following :

• Anti-ultraviolet
• Corrosion resistance
• Very low friction coefficient
• Excellent abrasion resistance
• No longitudinal crack formation or other stress cracks
• Low creep
• Unique chemical resistance
• Flexible, durable

The different types of PEX are distinguished by the manufacturing process used to make the tubing. When shopping for PEX, you may notice rolls labeled with either an A, B, or C designation. Choose the tubing best suited to your needs:

•  PEX-A is manufactured using peroxide. This type of PEX is the most flexible of the three types and is suitable for use in all home water-supply plumbing needs. It expands to the greatest degree when subjected to freezing water, so it’s the most resistant to cracking in frigid temperatures. It’s easy to work with but it’s more expensive than B or C. A 10-foot piece of PEX-A runs $3.50 to $7.50, depending on brand and diameter. Other than flexibility, PEX-A has no significant benefit over PEX-B.

•  PEX-B is manufactured using a moisture-cure method. PEX-B is slightly stiffer than PEX-A, and has a distinct coil “memory” that makes the tubing want to return to its original coiled state. The coil memory however, is not a hurdle to installation, and PEX-B is often the tubing of choice for residential plumbing because it also expands to resist cracking when water freezes but is less expensive than PEX-A: A 10-foot section of PEX-B runs $2.50 to $5.50, depending on brand and diameter. PEX-B also features an increased resistance to chlorine, making it a good choice in areas where water is highly chlorinated.

• PEX-C is manufactured via an irradiation method. Because it’s the stiffest version, PEX-C is the most difficult to work with; this stiffness also makes it most prone to kinking, as well as susceptible to cracking when water freezes. These undesirable traits make PEX-C best suited for short repairs where bending around sharp corners isn’t necessary. PEX-C is the most economical choice, with a 10-foot section running $1.75 to $3.50, depending on brand

Magstar PEX pipe extrusion machine line consists mainly of material color mixer, dryer, vaccum loader, single screw extruder,co-extrusion mould and die head, vacuum calibrating cooling tank, water cooling tank, online printer, traction haul-off machine, non-dust cutter, stacker or coiler, as well as auxiliary machine.

Feature of PEX Pipe Extrusion Machine:

• The barrel feeding zone is groove feed bush and made of hard alloy.
• It is result higher output rates, homogeneous plasticizing and material slippage.
• The water spray unit produces high speed spray nozzles to achieve fine and even cooling effect.
• Special design vacuum sizing can ensure the stability of diameter and roundness even when producing the pipe with higher wall thickness.
• Cost-effective energy and Material saving.
