Henan Jinhuaiyu Machinery & Equipment Co., Ltd., a dedicated manufacturer established in 2025, proudly introduces our Portable Corrugated Pipe Threader — a cutting‑edge solution designed specifically to reduce labor and accelerate girder prestressing duct construction. With a factory spanning 1,000–3,000 square meters and a skilled team of 51–100 employees, we combine modern production capabilities with hands‑on expertise. This threader is engineered to simplify threading of corrugated pipes into prestressing ducts, eliminating manual pulling and minimizing worker fatigue. Whether you are working on bridge girders, box girders, or tunnel segments, our equipment delivers consistent, reliable performance on every project.
Core Features & Technical Specifications
Portable & Compact Design – Weighing only about 35 kg with a carry handle, it can be easily moved between workstations and fits into tight construction spaces.
Adjustable Threading Speed – Speed can be set from 0 to 5 m/min, allowing operators to match the pace with pipe material and site conditions.
Wide Pipe Compatibility – Handles corrugated pipes with diameters from 50 mm to 120 mm, covering most common duct sizes used in prestressing.
Durable Construction – Built from high‑strength steel and wear‑resistant components, ensuring long service life even under heavy daily use.
Low Maintenance – Simple structure with easily replaceable wear parts; routine cleaning and lubrication are all that is needed.
Safety Features – Emergency stop button and overload protection safeguard both operator and machine.

Why Choose Our Portable Corrugated Pipe Threader?
Labor Reduction – Manual threading of corrugated pipes often requires 2–3 workers and causes physical strain. This machine allows a single operator to complete the task, cutting labor costs by up to 60%.
Faster Construction – With adjustable speeds up to 5 m/min, it can thread a 50‑meter duct in under 10 minutes, significantly improving project timelines.
Consistent Quality – The automatic feeding mechanism prevents pipe twisting or jamming, ensuring smooth and uniform installation every time.
Versatile Application – Ideal for highway bridges, railway viaducts, high‑speed rail, elevated roads, and any structure using post‑tensioned prestressing ducts.
Easy Operation – Intuitive controls require minimal training; new operators can become proficient within an hour.
