Taiyuan Huaxin Cheng Electrical Equipment Co., Ltd. is a high-tech enterprise specialized in the design, development and manufacture of welded pipe equipment, spiral welded pipe equipment, cold-formed steel equipment, sheet and pipe finishing equipment and high-precision slitting line equipment. Huaxin Cheng electromechanical Taiyuan, Shanxi reason to introduce you to spiral welded pipe welding equipment and precautions cracks weld cracking during welding weld defects are the most common form, in which the chemical composition of raw materials, welding, spot welding position inside, eccentric, welding specifications and wire spacing and spiral welded pipe forming processes such as the production of weld cracks have an effect. For the production of welding cracks appear, from the nature of the cracks were, welding materials, process and molding process and other reasons, and put forward before the production of raw materials for chemical analysis of different materials to choose the right wire, flux matching butt welding position, eccentric and fine precision of welding parameters. While improving the quality of steel molding, reducing the amount of pipe bombs complex, the production process parameters according to the requirements of these precautions strictly controlled manufacturing spiral welded pipe equipment, etc., to explore and study the actual production problems. Taiyuan Huaxin Cheng Electrical Equipment Co., Ltd. is a high-tech enterprise specialized in the design, development and manufacture of welded pipe equipment, spiral welded pipe equipment, cold-formed steel equipment, sheet and pipe finishing equipment and high-precision slitting line equipment. Taiyuan Huaxin Cheng introduce you to roll the design and manufacture of cold-formed device features are what? Learn Cold Equipment, although already have some, but not very much spiral welded pipe equipment offer enough yet comprehensive overview Cold Equipment. So, we have to continue to learn to go spiral welded pipe equipment, can not stand still, otherwise it will become obsolete. For these reasons, we have to continue to explain the following content knowledge Cold Equipment aspects in order to achieve this goal. Cold bending roll apparatus spiral welded pipe production equipment, which is a very important part of its design and manufacturing features are: (1) each pass to be the average force, to be able to wear leveling, and prolong the service life of the roll. (2) the general roll is the use C12MoV material because this material has good wear resistance, but note that between hardness and strength, and therefore properly handle the job. Spiral welded pipe production _ Huaxin Cheng electromechanical equipment (certified) _ Islamabad spiral welded pipe equipment provided by the Electrical and Mechanical Equipment Co., Ltd., Taiyuan Huaxin Cheng.
