Sandblasting pipe It is a kind of electric locomotive, which can be used for carrying out high-speed loads. It has many characteristics, such as good flexibility, fatigue mitigation, high pressure resistance, heat resistance, cold resistance, corrosion resistance, etc., and is required to be used on electric locomotive routes. All flexible tube. There are seven performance parameters: appearance, limit, impact resistance, sealing, rough static data and rough dynamic performance.
The appearance, limit, impact resistance and sealing of explosion are all included in the new items of original factory inspection, and seven items need to be inspected in the form test. If electric welding leakage occurs in the whole process of train operation, it will seriously endanger the safety of the train. Therefore, the electric welding quality of sand blasting pipe is very strict.
Tungsten rare gas maintenance welding (TIG welding) is an electric welding method under the maintenance of rare gas, in which the tungsten level and the arc heat between the product workpiece are used to melt the base material and filler wire (if filler wire is used). Argon is used as the maintenance gas for tungsten argon arc welding. At high welding temperature, argon does not react strongly with metal materials or dissolve in shape memory alloy.
Therefore, it has good safety protection effect for electric welding areas, and is very suitable for electric welding of medium carbon steel and carbon steel. The tungsten arc is reliable. Even if the welding current is small (10A), it can be burned reliably. Therefore, this kind of welding method is very suitable for thin metal plate welding, and can obtain good welding appearance. In order to reasonably ensure the welding quality, tungsten argon arc welding is adopted by combining the characteristics of metal bellows structure.
Sandblasting pipe The key structure is composed of metal bellows, Internet connector sleeve, connector sleeve, 1Cr18Ni9Ti and other materials. The metal corrugated pipe is made of thick wall seamless splicing or vertical electric welding stainless steel pipe, which is formed according to the fine plastic deformation, wall thickness, O or less than 5mm; The Internet address cover is made of stainless steel wire or steel chain and has certain main parameters. The mesh sleeves on both sides of the plastic hose are provided with waterproof sleeves for each connector with a wall thickness of 3mm. The wall thickness of the butt joint is more than 4mm. Because of the great difference in wall thickness, such as improper welding methods, simple composition fusion or poor welding and other defects.
