What are benders and their types
Pipe bender is a device that is a device or machine that allows to bend pipes of different shapes and from different materials. Several types of pipe benders will be described:
- Hand benders. They can be both small devices resembling pliers and placed in the hand, and rather large machines, for the activation of which it is necessary to exert quite considerable efforts. With the help of a hand-held bender, it is possible to bend a material of small diameter, while the accuracy of the device is low.
- Hydraulic bender. Pipe bending of this type is a device for bending a pipeline, the main working force of which is a hydraulic pump. The operation of the pump can be stimulated either manually or by an electric motor. The hydraulic pipe bender allows bending pipes up to four inches in diameter. The accuracy of bending as well as the probability of damage to bent materials is noticeably better than that of a hand bender.
- Electric benders have a wide range of pipe diameters with which it is possible to produce bending, as well as high accuracy of work and low probability of material damage. Electric benders do not require the use of human strength, except by pressing the control buttons. A big disadvantage of using this type of pipe benders is their very high price, which can reach several thousand dollars.
How to bend a pipe from metal-plastic
Metal-plastic pipes are widely used for mounting various communications. The advantages of using this type of pipe in their ease, bendability and ease of interconnection of their constituent parts. These pipes are most often used for bending because of the ease of use. To bend metal-plastic, either small hand benders or hand pressure are used. The main thing to consider is the fact that when expanding plastic materials, you can not immediately make too big changes in shape. This can damage the shell of the pipeline and spoil it. Flexible metal-plastic must be carried out gradually, changing the shape by several degrees.
How to bend a pipe from polypropylene
Polypropylene building materials are widely used in installation works of various communications. They are distinguished by a lower price and ease of bending and joining. Unlike metal plastic pipe products, which bend after the mechanical impact, polypropylene communications are bent only after heat treatment. This operation is carried out with the help of special heating devices or a mounting hair dryer. But when heating polypropylene material, it is necessary to observe some caution, because due to excessive heating it can become unusable.
How to bend a square shaped pipe
Profile building materials differ from others in their shape and high strength. Bending of tubular products of square shape( profile) is performed in cases when it is necessary to create a strong metal frame or other stable metal construction. For bending of this kind, benders are most often used. This requires hydraulic or electric flexors, because the square materials are very strong. If there is no tubing, you can apply a method of bending using sand. The way of bending with sand is made as follows:
- Sand is poured into the pipe, and the holes are clogged on both sides with stoppers.
- After this, the rubber hammer or mallet is gradually bending to the desired shape. In this case, sand does not allow the walls to deform and break the integrity of the shell.
- If necessary, the metal can be heated a little by a blowtorch, this will increase the foldability several times.
Thus, the article was given exhaustive information, which concerns the bending of the pipeline of different types. The above material will help at home use knowledge on the bending of pipe materials.
