bender - a device that is a device or machine that allows you to bend pipes of different shapes and made of different materials.Next will be described several types of benders:
PVC pipes are widely used installation of various communications.Advantages of application of this type of pipes in their lightness, bendability and ease of interconnection of their constituent parts.These tubes are most often used to ease of use due to bending.To bend the metal and plastic are used or small hand benders, or the pressure of the hands.The main thing to take into account the fact that the extension of metal-plastic materials can not be too soon to make a big change in shape.This can damage the pipe shell and spoil it.Flexible metal-plastic should be implemented gradually, changing the shape of a few degrees.
building materials are widely used in assembly operations of different communications.They are characterized by a low price and ease of bending and connection.Unlike plastic composite tubulars which are bent after mechanical impact polypropylene bend communication only after the heat treatment.This operation is carried out by means of special heating devices or mounting dryer.But when heated polypropylene material should comply with some caution, because of the excessive heat, it can come into disrepair.
Sectional gates differ from others by its shape and high strength.A flexible pipe products square shape (profile) is performed in cases where it is necessary to create a sturdy metal frame or other stable metal structure.For this type of bending is most often used benders.It should be hydraulic or electric flexors, because square materials are very durable.In the absence of bending tool can be applied method flexing with sand.bending method using the sand as follows:
Thus, the article was given comprehensive information, which relates to flexible pipes of various kinds.The above material will help in the home to use knowledge of bending pipe materials.
