Spiral Coils For Cold Simmering In Boiler Plants Lined Pipe Fittings
As the name suggests, the coil is a spiral pipe system. Such as disc-shaped aluminum-plastic pipes, such as floor heating pipe coils installed in the back shape, etc.
1. The influence of lubrication on product quality during the bending process: In the traditional bending pipe production process, enterprises will adopt many methods to obtain better surface quality of the bend, including: adopting more advanced and high-grade bends Machine, use higher strength molds, or use lubricating products and other methods.
2. When the pipe is bent, the outside of the material is stretched, and the position of the neutral axis under pressure on the inside is different from the bending method. In the top-bending type (compression bending), the neutral axis is located about 1/3 away from the outer wall. When bending (returning) work, the neutral axis is located 2/3 away from the outer wall. Therefore, when thin-walled pipes are bent, it is beneficial to use the twist bending method.
3. The accuracy of the bent tire is also one of the factors affecting the quality of the bent tube. When we manufacture bent tires, in addition to the specification and size requirements to be controlled within a certain tolerance range, we also require users to select the corresponding bent tires according to the bent pipe diameter during use.

Care and maintenance:
The process of boiler coil is to put an induction coil on the bending part of the steel pipe, clamp the pipe head with a mechanical rotating arm, and pass an intermediate frequency current into the induction coil to heat the steel pipe. When the temperature of the steel pipe rises to a plastic state, the steel pipe Use mechanical thrust to advance and bend, and the bent steel pipe part is quickly cooled with coolant. In this way, heating, advancing, bending, and cooling are performed to continuously bend the bent pipe. As the name implies, the galvanized elbow is galvanized on the basis of the elbow.
1. Operate strictly in accordance with the operating regulations.
2. Add lubricating oil at regular, fixed point and quantitative basis according to the requirements of the lubrication chart each time before starting the machine. The oil should be clean and free of precipitation.
3. The machine tool needs to be kept clean at all times, with anti-rust grease for the unpainted parts.
4. The lubrication oil in the bearings of the electric idea should be replaced and refilled on schedule, and the electrical department should always be checked for normal, safe and reliable operation.
5. Regularly check whether the V-belt, handle, knob, and button are damaged. If they are severely worn, they should be replaced in time, and the spare parts should be updated.
6. Check and repair switches, insurances, and handles on time to ensure reliable operation.
7. 10 minutes before the work day, lubricate the machine tool and scrub and clean the machine tool.
8. It is strictly forbidden for non-designated staff to operate the equipment, and it is usually necessary to leave the machine to stop.
The hydraulic pendulum pipe bender is a circular motion, and the production of the circular blade is quite difficult. Generally, the blade is used for shim compensation, so the gap obtained is not accurate, and the cut sheet is not ideal. Due to the arc movement, the blade can not be made into a rectangle, but should be made into an acute angle, so the force of the blade is not ideal, and the blade damage is also severe.
