Cold Applied PE Tape Manufacturing Machine for Gas Pipeline with PLC

Integrated PLC-controlled production line for cold applied polyethylene anti-corrosion tape used on gas, oil and municipal buried steel pipelines.

This cold applied PE tape manufacturing machine is built for producing cold applied polyethylene anti-corrosion tape used on gas pipelines, oil and gas transmission lines, natural gas distribution networks and municipal buried steel pipelines. It integrates PE base film extrusion, corona surface treatment, slot-die adhesive coating, slitting and multi-station rewinding in one PLC-controlled tape production line, so pipeline anticorrosion tape factories can run continuous, repeatable output with fewer operators.

Centered on a heavy-duty SJ-75X30 single-screw extruder with a hydraulic screen changer and type 1000 die head, this tape extrusion machine converts HDPE, LDPE and adhesive compounds into a uniform multi-layer PE adhesive tape with consistent peel strength, impact resistance and chemical durability. The line delivers 160–200 kg/h output at a maximum tape width of 1000 mm, giving pipe wrap tape manufacturers the capacity for large gas pipeline projects and export orders.

Backed by CE and ISO9001 certification, 21+ years of export experience and 400+ overseas customers, Huashida provides full OEM and ODM customization for this tape processing machine. Buyers can configure tape width up to 1000 mm, base film thickness 0.2–1 mm, adhesive thickness 0.1–0.5 mm, voltage and PLC brand (Delta) to match local power and project requirements. Tapes made on this line are commonly specified to SY/T 0414 and DIN 30672 pipeline tape standards. Every shipment includes overseas installation guidance, free technical support and a 12-month warranty.

A vacuum automatic feeder and hopper dryer deliver dried HDPE and LDPE to the SJ-75X30 single-screw extruder, where the material is fully melted and plasticized. The melt flows through a hydraulic screen changer and the die head mold (type 1000), then is shaped by multi-roller tape casting. This PE extrusion machine stage gives stable base film thickness (0.2–1 mm), flat surfaces and strong inter-layer adhesion for gas pipeline tape.

The film passes the integrated 1300 mm silicone stick corona processor, which raises surface energy so the hot melt adhesive bonds firmly to the polyethylene. The slot-die tape coating machine then applies 0.1–0.5 mm adhesive evenly on one or both sides, supported by a constant pressure system, force-feed device and 300 L adhesive reactor for uninterrupted batches. Magnetic powder brakes and clutches hold web tension steady, producing cold applied PE anti-corrosion tape with void-free bonding and lasting corrosion protection.

The coated master roll is slit to the required commercial widths (up to 1000 mm) and wound on the multi-station rewinding unit. Finished polyethylene tape rolls are ready for packaging, container loading and delivery to gas pipeline contractors and tape distributors worldwide.

This cold applied PE tape manufacturing machine delivers 160–200 kg/h output, corona-treated PE base film, precision slot-die adhesive coating and tension-controlled rewinding, ensuring consistent pipeline anticorrosion tape quality for gas pipeline, oil and gas, and municipal buried pipeline projects worldwide.

• PLC Automation: PLC and frequency converters synchronize extrusion, coating and rewinding, reducing operator dependence and keeping cold applied PE tape quality stable from batch to batch.
• Integrated Tape Manufacturing: Extrusion, corona treatment, coating and rewinding run in one continuous tape production line, cutting handling steps and material waste.
• Slot-Die Coating Precision: Uniform 0.1–0.5 mm hot melt adhesive on single or double sides gives void-free bonding and consistent peel strength for gas pipeline tape.
• Corona Treatment Integration: Higher surface energy before coating improves adhesive bonding to the PE substrate and reduces delamination risk in long-term buried service.
• 160–200 kg/h High Output: Sustained throughput keeps large pipe wrap tape orders on schedule.
• 1000 mm Maximum Tape Width: One tape extrusion machine line serves multiple tape width specifications without equipment changeover.
• OEM and ODM Service: Customize tape width, film thickness, adhesive thickness, voltage and PLC brand to produce your own branded polyethylene tape.
• 21+ Years Export Experience: 400+ overseas customers across Russia, Kazakhstan, Iran, UAE, Turkey, Nigeria and 60+ countries.
