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
- 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
Advantage of PEX pipe as following :
- 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
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
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
- 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
- Cost-effective energy and Material saving.
What's the necessary machines for making PEX pipes ?
A standard PEX pipe manufacturing plant factory should be including
the following necessary machines for making PEX pipes .
- HDPE granule material dryer
- HDPE granule material color mixer
- Vacuum Loader Machine
- Single Screw Extruder
- Extrusion Mould & Die Head
- Vacuum Calibrating Cooling Tank
- Water Cooling Tank
- Haul-off Unit Machine/ Traction Machine
- Cutter Machine
- Stacker or Coiler ( Optional)
What's the PEX pipe making process ?
PEX pipe making process is almost the same with other kinds plastic
pipes making process,such as HDPE pipe making process, PPR pipe
By the way, this machine can make HDPE pipe, PE-RT pipe or PPR
pipes too if change some parts only. So it can save some cost for
From the above general information, we can make a making process
chart of PEX pipe as following:
HDPE garnule + Main master batch ⇒Mixing ⇒Drying⇒Vacuum loading
⇒Hopper ⇒Feeding ⇒ Plasticizing
⇒ Co-extruding⇒Molding ⇒Forming ⇒Cooling ⇒Pulling ⇒Coiling/Stacking
