High pressure to low pressure tubing to the low-pressure pump to pump straight pipe straight pipe prices Our factory is producing concrete pump, pump accessories professional manufacturer main products are: HBT30,40,50,60,70,80 concrete pump pipeline; a variety of ground tube, horizontal tube, straight tube, pipe, adjustable tube, rubber hose, rubber seals, cleaning ball, cleaning column, cleaning piston, high voltage steel card and delivery of products and so on a two-layer mixing station The method of the elbow, the melting point of the solid filler is melted into a liquid, a solid filler between 30-350 ° C, and then poured into the outer tube and the inner tube of the double tube, to be filled with a filler after cooling to solid, and then the double-tube tube bending, when the end of the tube bending, and then the double-pipe heating the entire solid filler tube completely melted outflow, its advantages are: The method is applicable to a variety of structures The double tube bend processing; elbow stable quality of the processing methods, the inner wall can be effectively controlled through a solid medium within the tube, thereby ensuring the inner and outer wall even when bending deformation; and the processing method is simple auxiliary processing equipment into a small, and therefore lower costs due to the bending machine bends belong wound bending, bending radius size is usually to guarantee against mold. Single and double, it refers to the number of layers of mold. Three-dimensional stereoscopic tube type, single mold for bending multiple bends on one tube and a plurality of curved tube bending radius of the same size; if with a plurality of curved pipe bending, bending radius is not the same, it is necessary to use multi-mode automatic bending machine, for example, there are two different one tube bending radius, then choose double mode bender;.
