Plastic Pipe Extrusion Machine & Line

One Pipe Production Line, Eight Machines in Sequence

A plastic pipe extrusion machine is never one machine. A working pipe production line is eight units in a fixed sequence, and the quotation you compare is really a bill of eight decisions — extruder type, die head, calibration, cooling length, haul-off capacity, cutting method, downstream handling and control system. SUHUI builds these lines for HDPE, PPR and PVC pipe used in water supply, gas, drainage, plumbing and industrial service. Two inputs set almost everything: pipe material and diameter range. Material decides the extruder — a conical twin screw for PVC dry blend, a single screw with a grooved feed for HDPE and PPR. Diameter decides the physical size of every unit after the die, which is why a Φ20–110 mm line and a Φ315–800 mm line share a name but almost no components. As a factory-direct manufacturer we quote the line against your product standard rather than a catalogue model. Pipe plants also generate a steady stream of start-up purge, off-spec lengths and cut-off ends; PVC producers recover that scrap in-house with a PVC granulating pelletizing line instead of selling it as waste. Comparing pipe against profile or straw production? The plastic extrusion machine overview sets the three side by side.

Selection Guide

Which Pipe Line Fits Your Product?

Material / project situation	Recommended machine	Why it fits
Water supply, gas, sewage and industrial pipe	HDPE Pipe Extrusion Line	A grooved-feed single screw with high output per rpm, and the longest cooling section of the three because HDPE holds heat. Large diameters need vacuum tanks in series rather than one longer tank, which is the main reason big-bore HDPE lines take so much floor length.
Hot and cold water plumbing, multi-layer and fibre-reinforced pipe	PPR Pipe Extrusion Line	Mechanically close to an HDPE line, but usually specified with co-extrusion for a middle glass-fibre or colour layer. If you plan to make PE-RT or PB pipe on the same line, say so at the quotation stage — it changes the screw and the temperature control, not just the recipe.
Drainage, electrical conduit and rigid pressure PVC pipe	PVC Pipe Extrusion Line	A conical twin screw is standard because PVC is fed as dry blend powder, not pellets, and needs shear plus a short residence time. Small-diameter conduit is normally run twin-cavity, so one line produces two pipes at once and the economics change completely.
You have a drawing or sample but no fixed material yet	Send the specification first	Wall thickness and pressure rating decide material as often as the other way round. Send the standard you are producing to, the diameter range and the target output per hour, and the material choice usually resolves itself.

Typical Pipe Extrusion Process Flow

01 Material feeding and drying Gravimetric or volumetric dosing, plus drying for PPR and any hygroscopic material. Dry blend for PVC is mixed and cooled before it reaches the hopper, and inconsistent blend here shows up as colour and wall variation hundreds of metres later.
02 Extrusion Conical twin screw for PVC dry blend, grooved-feed single screw for HDPE and PPR. Output is set by screw diameter and speed, but melt quality is set by temperature profile, and it is melt quality that decides whether the pipe passes pressure testing.
03 Die forming The die and the spider or basket design set wall distribution around the circumference. Each diameter range needs its own die and calibration sleeve, which is why extending a line to a new size is a tooling purchase rather than a setting change.
04 Vacuum calibration The tank that fixes outside diameter. Vacuum holds the soft pipe against a calibration sleeve while the wall sets. Vacuum stability matters more than tank length here, and it is the first place to look when outside diameter drifts.
05 Cooling Spray or immersion tanks in series. Cooling length scales with wall thickness and line speed, not with diameter alone. Under-cooled pipe keeps shrinking after the haul-off and comes out of tolerance at the far end of the line.
06 Haul-off Caterpillar tracks that pull the pipe at constant speed. Haul-off speed against extruder output is what sets wall thickness, so the two are controlled together. Track count rises with diameter because grip has to spread over a larger surface.
07 Cutting Planetary saw for large-bore rigid pipe, guillotine or flying saw for small diameters. The cut has to happen while the pipe keeps moving, so the saw travels with the line and returns between cuts.
08 Stacking or coiling Tipping table for cut lengths, coiler for small-diameter HDPE and PPR. This is the stage most often under-specified: a line that extrudes 500 kg/h but stacks by hand will run at whatever speed two operators can keep up with.

HDPE, PPR and PVC Lines Compared

The three share a process and very little hardware. These are the differences that change the quotation rather than the brochure.

Line type

HDPE

PPR

PVC

Extruder

HDPEGrooved-feed single screw, high output per rpm.

PPRSingle screw, often with a co-extruder for the middle layer.

PVCConical twin screw, because the feed is dry blend powder.

Typical use

HDPEWater mains, gas, sewage, cable duct, industrial service.

PPRHot and cold plumbing inside buildings.

PVCDrainage, electrical conduit, rigid pressure pipe.

Diameter range

HDPEΦ20–800 mm, coiled below Φ110 mm.

PPRΦ20–800 mm, though most demand sits under Φ160 mm.

PVCΦ16–630 mm, twin-cavity below Φ40 mm.

Cooling demand

HDPEHighest. HDPE holds heat, so the tank series is long.

PPRHigh, and uneven across layers on co-extruded pipe.

PVCLowest of the three at the same wall thickness.

Watch for

HDPEFloor length. Large-bore lines need tanks in series, not one long tank.

PPRConfirm at quotation whether PE-RT or PB will run on the same line.

PVCDry blend consistency upstream decides pipe quality downstream.

If you produce more than one of the three, do not assume one line covers them. The extruder is the part that does not transfer. Downstream equipment can sometimes be shared across materials in the same diameter band; the extruder almost never can.

Material-specific configurations are set out on the HDPE pipe extrusion line, PPR pipe extrusion line and PVC pipe extrusion line pages.

Diameter Bands and What Each One Costs You in Output

Diameter is the single variable that resizes every machine after the die. Output falls as diameter rises, because wall thickness rises with it.

Diameter band	Typical output	Extruder class	What changes at this size
Φ16–63 mm	120–250 kg/h	Small	Twin-cavity dies are viable, so one line can run two pipes at once. Coiling replaces cutting on flexible materials.
Φ50–160 mm	250–450 kg/h	Medium	The most common band worldwide. Single-cavity die, cut lengths, tipping table. Everything is standard and lead times are shortest.
Φ110–315 mm	400–700 kg/h	Large	Vacuum tanks go into series and the haul-off gains tracks. Floor length starts to drive the plant layout rather than the other way round.
Φ315–800 mm	600–1,200 kg/h	Extra large	Planetary cutting, multiple cooling tanks, heavy handling. Output per hour is high but metres per minute is low, so wall thickness eats the throughput.

Read the two right-hand columns together. A line quoted at 1,000 kg/h for Φ630 mm pipe is slower in metres per minute than a 250 kg/h line making Φ32 mm conduit. If your business is priced per metre rather than per kilogram, specify from line speed, not from kg/h.

Lines are normally built to cover two adjacent bands. Asking one line to span Φ20–630 mm means tooling for every size in between and a compromise on all of them.

The Eight Machines in a Pipe Production Line

This is what you are actually buying. Each unit is quoted separately and each one can be the bottleneck.

Feeding and dryingDosing, plus a dryer for PPR and a blend cooler for PVC powder.
ExtruderConical twin screw for PVC, grooved-feed single screw for HDPE and PPR.
Die headSets wall distribution. One die per diameter range, not per line.
Vacuum calibration tankFixes outside diameter while the wall sets. Vacuum stability decides tolerance.
Cooling tanksSpray or immersion, in series. Length scales with wall thickness and line speed.
Haul-offCaterpillar tracks. Speed against extruder output is what sets wall thickness.
CutterPlanetary saw for large bore, guillotine or flying saw for small. Cuts on the move.
Stacker or coilerTipping table for cut lengths, coiler under Φ110 mm. Most commonly under-specified unit.

When you compare two quotations, compare them unit by unit. A cheaper line is usually cheaper at the far end — a shorter cooling section, fewer haul-off tracks or manual stacking. Those three are exactly where a line loses the output it was sold on.

What Drives the Cost of a Pipe Extrusion Line

Diameter range moves the price more than any other variable, because it resizes seven of the eight units at once.

PVC line

$25,000–85,000

HDPE / PPR line

$35,000–150,000

Factory-direct FOB for budgeting. Excludes sea freight, duties and on-site installation.

PVC pipe line by diameter	Reference FOB	HDPE / PPR pipe line by diameter	Reference FOB
Φ16–40 mm (twin-cavity)	$25,000–30,000	Φ20–110 mm	$35,000–40,000
Φ50–160 mm	$30,000–35,000	Φ50–250 mm	$40,000–50,000
Φ75–250 mm	$35,000–40,000	Φ160–450 mm	$65,000–75,000
Φ110–315 mm	$45,000–50,000	Φ280–630 mm	$85,000–100,000
Φ160–450 mm	$50,000–60,000	Φ315–800 mm	$90,000–150,000
Φ315–630 mm	$75,000–85,000	—	PPR is priced in line with HDPE

Inside a diameter band, three options account for most of the spread: co-extrusion layers, online wall-thickness gauging and the level of automation at the stacking end. None of them changes the pipe you can make; all three change how many operators the line needs and how much scrap it produces.

Frequently Asked Questions

What plastics can be used for pipe extrusion?

Common pipe materials include HDPE, PPR and PVC. Each material uses a matched extruder, die and calibration setup.

What equipment is included in a pipe extrusion line?

A typical line includes material feeding and drying, extruder, die head, vacuum calibration, cooling tanks, haul-off, cutting and stacking or coiling equipment.

Can pipe size be customized?

Yes. Pipe diameter and wall thickness ranges are configured through the die, calibration sleeves and downstream equipment based on your product standard.

What information is needed for a pipe extrusion quotation?

Send the pipe material, diameter range, wall thickness, required output, plant space, local voltage and destination country.

How much does a plastic pipe extrusion machine cost?

A PVC pipe line runs USD 25,000 to 85,000 FOB and an HDPE or PPR line USD 35,000 to 150,000, depending mainly on diameter range. Small conduit lines sit at the bottom of each range and large-bore lines at the top, because diameter resizes the die, calibration tank, cooling tanks, haul-off and cutter all at once. Co-extrusion, online wall gauging and automated stacking are the main options that move the price inside a band.

What equipment is included in a pipe production line?

Eight units in sequence: material feeding and drying, extruder, die head, vacuum calibration tank, cooling tanks, haul-off, cutter, and stacker or coiler. Each is quoted separately, and each can be the bottleneck. When comparing quotations, check the cooling length, the number of haul-off tracks and whether stacking is manual, because that is usually where a cheaper line is cheaper.

Can one line produce HDPE, PPR and PVC pipe?

Not practically. PVC is fed as dry blend powder and needs a conical twin screw; HDPE and PPR are fed as pellets and use a grooved-feed single screw. The extruder is the part that does not transfer between them. Downstream equipment can sometimes be shared across materials within the same diameter band, but the extruder has to be matched to the material.

What output can a pipe extrusion line achieve?

Roughly 120 to 250 kg/h at 16 to 63 mm, 250 to 450 kg/h at 50 to 160 mm, 400 to 700 kg/h at 110 to 315 mm and 600 to 1,200 kg/h at 315 to 800 mm. Note that kg/h rises with diameter while metres per minute falls, because wall thickness rises too. If your costing is per metre rather than per kilogram, specify the line from line speed instead.

How much floor space does a pipe extrusion line need?

Length is driven by the cooling section rather than by the extruder. A small conduit line fits in roughly 20 to 25 metres, a mid-range line needs 30 to 40 metres, and large-bore HDPE lines run past 60 metres because vacuum and cooling tanks are placed in series. Send your available length with the enquiry, since it sometimes limits the diameter range more than budget does.
