Processing seamless stamping elbow pay attention to which
Seamless stamping elbow after welding permeability is more improved, too easy to crack, if it is the same type of stamping elbow welding, the first preheating of the eye after welding is suitable for temperature above, welding parts can not be post-welding heat treatment, therefore, in order to ensure the quality of seamless stamping elbow, should be used in the welding process at different temperatures
Seamless stamping elbow processing points of attention
In order to increase the corrosion and welding performance of the seamless stamping elbow, add chemical elements in the processing process, it should be noted that when using the same type of processing, it is necessary to preheat more than 200 degrees Celsius after welding, the coating of the seamless stamping elbow is low hydrogen type, which can be used for DC and AC, but it is noted that in the welding process is shallow and easy to red, in use, Try to use the DC power supply is better
In order to prevent the coating of the stamping elbow from sticking to the oil and other dirt, it should be maintained in a dry environment, after the elbow is painted, it should be dried at 100-1500 degrees Celsius for 1-1.5 hours, in order to prevent the carbon content of the elbow weld, which will affect the quality of the welding parts
Stamping elbow welding drying, do not repeatedly dry, otherwise it will cause the coating easy to crack and drop, welding elbow, after heating will be discharged carbide, repeated heating will be discharged carbide, these carbides reduce corrosion resistance and mechanical, therefore, the welding process need to control the temperature of elbow, can not be repeated heating.
The raw material not only has a qualified creep fracture curve, but also the pipe price is moderate, compared with other products, the construction is convenient and fast, and the connection form belongs to the current reliable standard mutual fusion and hot melt connection form.
The diameter of the pipe is larger than the inner diameter of the pipe of the same specification. In the system, the fluid resistance of the system is relatively small because there is no mechanical connection of local reducing diameter
With the increase in demand for seamless stamping elbows, manufacturers are also developing rapidly, seamless stamping elbows belong to the production of finished products, installation and processing is relatively simple, only need to connect, the overall operation is relatively easy to install, the design of the slot panel can be removed panel, can make maintenance more convenient
The above is the processing of elbow need to pay attention to several aspects, if there is a problem, please contact us to understand the other knowledge of elbow, pay attention to the website
