One forming principle serves many pipe products. The same line concept covers welded pipes for steel structures, scaffolding tubes, furniture tubes, fence and guardrail pipes, greenhouse frames, storage rack tubes and fluid transmission pipes. Tell us the pipe you want to produce, and we will configure the forming and welding units around it.
Structural welded pipes carry frames, columns and bracing in steel buildings. Weld consistency and straight, accurate lengths decide how fast the structure goes up, so the sizing section and cutting unit matter on every pipe.
Scaffolding tubes are produced in high volume at standard diameters. A line running at up to thirty meters per minute with automatic cutting to length matches the batch sizes that rental companies and contractors order.
Furniture makers use round, square and rectangular tubes across many sizes and small batches. Tooling is built per drawing to cover the full size range in your product catalog.
Water and gas transmission pipes need seams that hold pressure over years of service. The high-frequency welding unit and sizing section keep the weld consistent along the full length of each pipe.
Solar mounting structures use galvanized tubes for posts and supports. Galvanized strip runs cleanly through forming and welding, and cut lengths follow the rack design.

About Us Certifications Engineering Cases
The pipe range covers diameters from one to ten inches, and the exact range is set per customer requirement. Square and rectangular tube sizes are tooled to your drawings as well.
The product range covers downspouts, water pipes, ducts and ERW welded pipes. These pipe products serve steel structures, scaffolding, furniture, fencing, greenhouses, storage racks and fluid transmission.
Line speed goes up to thirty meters per minute depending on the pipe diameter, wall thickness and welding configuration. We confirm the speed for your pipe specification before quoting.
Yes. OEM and ODM cooperation is supported, including white label supply for equipment brands and distributors. Branding, documentation and machine appearance can all follow your requirements.
Square and rectangular tubes start as round welded pipe and are reshaped in the sizing section. One line covers round, square and rectangular sizes within its range by changing the sizing tooling.
Send the pipe diameter and wall thickness range, the tube shape, the material grade, your target output and your plant voltage. With these we configure the forming, welding and cutting units for your product.
Yes. Engineers are sent to your site for installation, commissioning and operator training, and remote video support continues after startup. Warranty service runs twelve months for the main machine and eighteen months for core components.
Pipe forming equipment covers several machine types that share one forming principle. This guide explains the differences, so you can specify the right line for the pipe products you plan to sell.
A pipe forming machine converts flat steel strip or coil into round, square or rectangular tubes. Tube roll forming bends the strip progressively through roller stations until the edges meet, and the product then moves to welding or seaming depending on the pipe type. The finished tubes serve steel structures, scaffolding, furniture, fencing, greenhouses, storage racks and fluid transmission, which makes pipe equipment one of the widest-application machine categories in metal forming.
High-frequency welded pipe, also called ERW pipe, is made by heating the strip edges with a high-frequency current and pressing them together to forge the seam. After welding, the sizing section controls the final diameter and roundness, and a cutting unit separates the pipe to length. An ERW pipe making machine is configured around your diameter and wall thickness range, because welding power, forming stands and sizing stands all follow the pipe specification.
Downspout roll forming machines produce the downpipes that carry rainwater from roof gutters to the ground, in round or rectangular sections with the seams and bends that each market's building standard calls for. Building-products manufacturers often order a downspout machine together with water pipe or duct machines, and sourcing these from one supplier keeps tooling standards and spare parts consistent across the workshop.
The pipe range on THRONCH lines runs from one to ten inches, set per customer requirement. Each diameter needs its own tooling, and square or rectangular tubes are reshaped from round pipe in the sizing section, so a square pipe roll forming machine covers both round and shaped tubes within its range. Define the diameters you actually plan to sell before ordering, and the tooling package will be built around that list.
Five items let a manufacturer configure a pipe line correctly: the diameter and wall thickness range, the tube shape, the material grade, your target output, and your plant voltage. With these confirmed, the forming stands, welding unit, sizing section and cutting unit are all specified against your product instead of catalogue assumptions.
We're THRONCH, a direct factory in Wuxi, China, building custom roll forming lines for purlins, highway guardrail, cable tray, strut channel, and welded tube. Send us your profile drawing and get a line proposal within 24 hours.
