PPR Pipe Extrusion Line

Your Premier PPR Pipe Extrusion Line Manufacturer

PPR pipe extrusion machine line is used for making different diameters and thickness of PPR pipes , which is used for the hot water and cold water supply system.

PPR is a polypropylene random copolymer pipe. They are suitable for cold and hot water pressurized plumbing and mechanical systems. It is usually joined by means of fusion welding,either as a end to end （butt） weld or a fusion weld into a fitting hub. There are mechanical slip fit fittings, but the big advantage is the economy and structural integrity of the fusion weld. This type of joining, if done correctly makes two pipes into one longer pipe.

PPR pipe has the following application:

--Residential cold and hot water system

1. What's the purpose of your PPR pipe used for ?

If we have a plan and want to buy PPR pipe extrusion machine, first of all, we should know that what's the purpose of PPR pipe used for.

PPR pipe and fittings are a hot and cold water supply system suitable for all potable water applications and heating systems.The pipes are made from PPR, the most advanced PPR available today and injection molded fittings are made of Polypropylene Random （PPR） type 3.This rigorous, long lasting （50 years or more）， leak free system is joint by fusion welding, ensuring a homogeneous plastic system similar to PE pipe systems.

PPR is designed for applications, such as:

--Hydraulic works in residential, industrial and public projects

--Compressed air systems （air-conditioning）

--Drinking water and food liquids

--Agriculture （watering systems for green houses and gardens）

3. What's the necessary machines for making PPR pipes and what's these machines used for?

A standard PPR pipe manufacturing plant factory should be including the following necessary machines for making PPR pipes .

PPR granule material dryer

PPR ganule material dryer machine is main used in drying and stiring mixed PPR granule resin with color master batch by hot air, due to PPR granule material with special characteristics and PPR tube needs highest drying grade material.

PPR granule material color mixer

PPR pellet material color mixer machine is main used in PPR granule resin adding, drying, coloring and mixing with color master batch （ mostly is green/white master batch） according to different colors or surface requires for making differen color line function purpose.  PPR pellet material color mixer machine is composed of silo,motor, gear reducer box, stir blade and control cabinet.

Vacuum Loader Machine

Vacuum loader machine is used for loading PPR granule resin material into hopper on the top of single screw extruder from ground. PPR pellet resin material will be transported by vacuum covery in the middle of soft PVC suction hose pipe automaticly. It is controlled by timer too.

Single Screw Extruder & Co- Extruder

Single screw extruder is main part of PPR pipe making machine line. It is used for feeding,transporting, plasticing,melting PPR resin material.

Co-extruder is used for making color line of PPR pipes. Some customers need two different color lines on the surface of PPR pipes, so it will adpots two sets of co-extruders for making color lines. Anyway, in normal, one color line should be equipped one set of color co-extruder seperatly.

Single screw extruder and co-exturder are all composed of driven motor, gear reducer box, screw and barrel, casting aluminum heater, cooling blower, hopper and control cabinet.

Co-Extrusion Mould & Die Head

Co-extrusion mould and die haed is another important part of plastic PPR pipe production line. PPR granule material will be forced into extrusion die and melted mixing together through connect flange by screw forward transported after plasticizing and melting in the inner side of barrel. Due to extrusion mould and die head are under heatting too and it is still on fluid status after plasticizing and melting in the inner side of barrel on the single screw extruder, mixed PPR resin material can be come out from die head easy as people required shap,diameter and thickness.

PPR pipes with red strips, signal that they are for hot water.And those with green stripes, channel cold water. In the PPR pipe extrusion plant, we use a plastic pipe color marking line small/mini extruder for marking. That's the reason we use co-extrusion die head for joint extrsuion . 

Vacuum Calibrating Cooling Tank

Vaccum calibrating cooling tank is main used for cooling hot PPR pipes which is from extrusion mould die. It consists of tank body, vacuum pump, water pump, water spray nozzles system, temperature of water control system.

Tank boady is made by stainless steel because of there is water inside of tank and it is should be anti-rust. Length of tank is must be enough to cooling down the temperature PPR pipes when PPR pipe come out from tank. Length of tank is 6 meters or 9 meters according to diameter and thickness of PPR pipes.

Temperature of water control system is used for changing circuit water in time. As we know, after running some time, the temperature of water in the tank will be rising due to cold water take the heat quantity from hot PPR pipes and cooling efficiency will be down. So control system will start to drain the hot water from tank body and supply new cold water into tank body automaticly when temperature of water reach to setting temperature value.

Water Cooling Tank （ Two sets）

Water cooling tank is main used for cooling hot PPR pipes which is from vacuum cooling tank. It consists of tank body,  water pump, water spray nozzles system. Due to PPR pipe is very hard to cooling down, so we need another two sets of water cooling tank for cooling PPR pipe again.

Haul-off Unit Machine/ Traction Machine

Haul-off unit machine/ traction machine is main used for clamping and pulling the PPR pipe forward a long length at a constant speed through rubber pad which located on each pedrail.It consits of driving motor, pedrail/ pulling belt, air cylinder, rubber pad. According to PPR pipe diameter range, haul-off unit machine will be equipped 2, 3 pedrails/pulling belts for make sure traction force is enough to pull PPR pipe forward.

Cutter Machine

Cutter machine is used for cutting PPR pipes automaticly by PLC controller according to setting length. Working principle is that there are clamps which controlled by air cylinder for clamping PPR pipes first, then blades which on one movable plate start to cutting PPR pipe, meanwhile movable plate be start to moving forward along the guide rail and keep the same speed with extrusion line speed , because PPR pipe is continuous extruding and not stopping.

Stacker or Coiler （ Optional）

Stacker is used for stock final PPR pipes according to it's diameter range. It consits of air cylinder, wheel and steel frame.

Coiler is used for winding smaller PPR pipe automaticly. There are two type of coilers, one type is single disc coiler, anther one is two disc coiler.

4. What's the PPR pipe making process?

PPR pipe making process is almost the same with other kinds plastic pipes making process,such as HDPE pipe making process, PVC pipe making process.  Sure, it is also some different with other plastic pipe making process too. Due to there are color lines of PPR pipes, so we always use co-extruder machines together with main single screw extruder for making PPR pipes.

By the way, this machine can make PE-RT pipe or HDPE pipes too if change some parts only. So it can save some cost for customers.

From the above general information, we can make a making process chart of PPR pipe as following:

PPR garnule + Color line master batch ⇒Mixing ⇒Vacuum loading ⇒Hopper ⇒Feeding ⇒ Plasticizing

PPR garnule + Main master batch ⇒Mixing ⇒Drying⇒Vacuum loading ⇒Hopper ⇒Feeding ⇒ Plasticizing

⇒ Co-extruding⇒Molding ⇒Forming ⇒Cooling ⇒Pulling ⇒Coiling/Stacking ⇒Packing
