A stainless steel pipe expander is an essential tool for anyone working with piping. These devices are designed to increase the diameter of pipes, allowing for efficient connections and improved flow through the system. In this article, we will look at why you need an expander, what options are available on the market, and where to buy them.

Benefits of Using Expanders

Pipe expanders, including automatic and CNC models, provide high precision and reliability in operation. They create smooth and neat expansions, which is especially important for chimneys. A device with a groove for a rubber band ensures that the connections are tight, which prevents leaks and improves the efficiency of the system.

Types of Expanders

Automatic expander - ideal for large volumes of work. It reduces production setup time and increases overall efficiency.

CNC expander - automatic stretching machines and models with numerical control provide maximum precision and the ability to create complex shapes.

Chimney expanders - are needed to increase the diameter of chimney pipes, which improves their efficiency and promotes better ventilation.

Pipe coupling machine - used to connect pipes of different diameters, which provides additional versatility.

Where to buy a pipe expander in Kyiv

For those looking to buy a pipe expander in Kyiv, the market offers a wide selection. You can contact specialized building materials stores or use the services of online stores. Pay attention to offers that include economical options and premium devices, such as the Hornung W6, known for its reliability and quality.

Verstat KKD 1 - solution for the production of flue couplings made of stainless steel from the TM “Rosa Vitriv”

Current technologies for the installation of smoke-powered systems require high accuracy, reliability of connection and smooth folding. For the most important tasks, the representatives of the company “Rosa Vitriv TM” developed and distributed a hydraulic workbench with numerical program controls KKD 1. This specialized equipment is intended for the molding of couplings on stainless steel pipes using the method of precise expansion of the end part.

The main purposes of the KKD 1 versat:

Verstat is used for deformation of pipes by means of uniform stretching of the metal at the end, creating a smooth expansion, the necessary molding of the coupling. This connection allows you to insert one pipe into another without the need for welding. This is especially important during the production of dimars, to ensure the integrity of the connection and the safety of the entire structure.

Instead of stick welding, the use of a vikoristan coupling has a harmless advantage:

Simple folding - the pipe is easily inserted into the widened end of another pipe.

Reduced temperature control ensures a uniform connection of pipes, without sharp transitions and stress points that could overheat.

Saving time and cost for brewing – especially for streaming production.

High tightness - especially when combined with the gums of the gorge.

Technical characteristics of the KKD 1 workstat

Engine power: 4 kW

Diameter of the pipe to be cut: diameter 57 mm

Pipe wall thickness: up to 2 mm.

Control: scabbard, with two pedals

Cylinder stroke: adjusted using additional end sensors

Dimensions of the workbench: more compact, allowing for production in small and medium-sized production workshops.

Price: 5,500 €

The collets are bathed firmly, which makes it possible to fine-tune them for a specific task

Ergonomics and productivity

The device is designed to provide comfort and safety for the operator. Gentle control relaxes your hands, and manually moving the flaring unit minimizes fatigue. The simplicity of the design makes it easy for personnel to train and quickly implement the manufacturing process.

The verstat practically does not require maintenance, except for periodic monitoring of the hydraulic oil level. Reliability of ownership is confirmed by a real guarantee from the manufacturer.

Expansion of possibilities

KKD 1 sum with specially designed rubber collets, including collets for rubber gum. We need universal solutions for:

♦ smoke pipes;

♦ ventilation and drainage systems;

♦ exhaust pipes made of stainless steel.

Why rob "Rose of the Winds" ™

The company is promoting not only the layout itself, but also a new set of additional equipment:

collets for any diameter;

elements for forming grooves for gullies;

consultations to select a configuration;

prompt delivery and technical support.

The vikorstan KKD 1 type of TM “Rosa Vitriv” ensures stable product strength, precise coupling geometry and high productivity. It is suitable both for small workshops and for large production lines, since fluidity and minimization of the gap is important.

We supply expanding collets for sealing rubber (for chimneys).

Published:

1. It can be used as a workbench for the production of stainless steel exhaust pipes.

There is no need to weld the pipes using the "butt to post" method, but you can prepare a sleeve, insert the pipe into the pipe, and then boil it, which significantly speeds up the process and reduces the presence of exhaust gases on the construction site.

Stainless steel pipe expander

W6 electromechanical hydraulic machine

designed for fast and accurate one-sided expansion of thin-walled metal pipes (chimney, drain, ventilation, etc.)

Cost 17,600 euros

Machine W6 technical characteristics:

Hard plastic collets prevent subsequent corrosion, as welding of iron material is not performed in the case of stainless steel pipes,

plastic collets provide a huge advantage when working with large diameters due to reduced weight (approx. 85%),

the collets are held together by spring elements, so they can be easily replaced and do not need to be manually reinstalled after expansion,

from jaw diameter 300 mm, handles with integrated return springs are available.

Working range is standard: diameter from 60 to 1000 mm, delivery of special versions is possible. Thanks to the rotary release handle, the machine can be operated from three sides.

The expansion unit can be tilted more than 90 degrees to either side and is adjustable in height from 570 mm to 855 mm.

The gas spring support maintains balance at all times. The expansion stroke is adjusted by adjusting the wear-resistant sensor according to the range in millimeter divisions.

This allows the adjustment to be reproduced at any time.

Digital displays and touch panels can be supplied as options.

Various programs are available for touch panels, such as memory programs or step programs.

The material support is equipped with a bayonet connection and can be easily changed manually to a different size. (Standard slabs up to a pipe diameter of 350 mm)

A second, smaller expansion unit covers an area with a diameter of 60 to 120 mm.
