The production and production process of welding elbow bends is described by Zhangzhou Xindingsheng Pipeline Complete Equipment Manufacturing Co., Ltd. as follows:
The welding elbow is made of steel plate as the raw material. Firstly, after the steel plate is cut into materials according to the requirements, it is molded by stamping, and is also punched into a circular shape by punching, and the same two are combined, welded, shaped, etc. due to the weld. Exist, so non-destructive testing is required, and heat treatment is required due to the presence of welding stress.
Welding elbow bends has two more steps than push elbow bends: one is flaw detection, the other is heat treatment, and the other procedures are the same as the elbow manufacturing process. Tube production process. There are also many methods for processing pipe fittings. Many are also in the category of machining, and the most used are stamping, forging, roller processing, rolling, bulging, stretching, bending, and combination processing.
Pipe processing is an organic combination of machining and metal pressure processing.
Non-pressurized Solar Water Heater is a cost-effective system for residential hot water application. this system is designed according to thermosiphon principle and operating with proportion difference between cold and hot water. The water heated by Vacuum Tubes is held in the stainless steel storage tank where the insulation preserves the heat.
The thermosiphon solar water heater uses the sun to heat the working fluid (mostly water) in the vacuum tubes. The Solar Collector absorbs solar radiation, and converts the sunlight to heat and transfer it to the water. The heated water naturally rises through the solar collector into the water tank where the cooler water at the bottom of the tank is forced out and descends to the bottom of the collector (thermosiphon circulation). The circulation will be interrupted when there is no solar radiation.
Advantages
