Pipe reducing processes generally include two primary modes:
Rotary swaging：Radial Compression with Multiple Hammers is employed for medical-grade tubing applications.
Die swaging：Tapered Die Axial Pushing for Pipe Reducing is typically used for hydraulic fittings.
It presses the pipe into a mold to reduce its diameter, thereby obtaining consistent, sturdy, and clean pipe ends. No cutting or welding is required, reducing the rate of material loss. The output shapes and ends of these pipes also support customization, such as Tube Expanding and flare.
A tube expanding machine is a dedicated device that radially expands tubes through mechanical or hydraulic means, achieving tight conformity between the tube and tube sheet.
Commonly used tube expansion equipment:
The pipe flaring process is a tube end forming technique that cold-forges the pipe end using a die.
Flanging is the process of forming flat, raised, or sloped edges at the end of a tube to provide attachment points for other components. The flanges we can form can be single, multi-layer and shaped. They can be of various shapes, such as round, rectangular, square, etc.
The machine that forms annular bulging ribs on the mid-section of tubes through high-speed spinning wheel compression – creating radial compression without altering the tube’s profile – is termed bulging rib forming equipment.
The motor drives the upsetting die to vertically switch dies and horizontally feed, performing cold upsetting and extrusion on tubes for manufacturing fuel nozzles, oil pipes, automotive fittings, and A/C lines。
In addition to standard tube end forming techniques, auxiliary processes such as grooving and crimping also play an important role.
Using a rotating tool to cut and shape, one or more grooves are machined on the pipe end to achieve quick connection. Our grooving equipment can be customized based on your industry’s needs, with adjustable groove depths and shapes to match your application requirements.
The Tube Grooving Capacities：
The rolling process forms a uniform corrugated structure on the tube end by roller extrusion. It supports single-wave, double-wave, multi-wave, and other shapes, and is suitable for metal tubes such as stainless steel, copper, and aluminum.
The Tube Beading and Corrugating Capacities：
Below are examples of finished products from the tube end forming process, including precision flaring, non-marking reduction, and many other finishes that demonstrate our technical capabilities and craftsmanship.
