Knowledge of stainless steel butt welding elbows
Stainless steel butt welding elbow is suitable for pipe connection, has the advantage of simple structure, has been widely used in the construction and composition of pipelines, in the composition of the stainless steel butt welding elbow and other metals should be separated, in order to prevent other reactions
Stainless steel butt welding elbow in bending strength, light net weight is small, is a kind of horizontal hollow section of steel, welding process, the temperature should not be more than 60 degrees Celsius, should be protected in the weld inside, cutting can not use ordinary wheel cutting, should be used stainless steel butt welding elbow special grinding wheel or plasma cutting
Features of stainless steel butt welding elbow
Stainless steel butt welding elbow is to connect different pipes, or change the diameter of the pipe, this kind of elbow can also be required to meet special requirements or special requirements of the drawing, in addition to meet the requirements of pipe diameter, should also consider the situation in the pipeline, if the pipeline pressure, fluid viscosity, abrasive, corrosive fluid transport and other factors should be taken into account, Stainless steel butt welding elbow with weld.
Elbow welding rust or corrosion is after welding operation, or the environment outside the pipe rust treatment, in order to avoid bending rust or corrosion during welding.
The use of stainless steel materials is generally in the pipeline construction site welding welding elbow, because all kinds of pipeline welding standards are not the same, so according to the welding level of the pipeline field welding, the need for different pipeline welding levels to the field welding, this is another feature of welding elbow
Note steps for purchasing stainless steel butt welding elbows
In addition to determine the material, then is the size of the specification, thickness and other issues. Most buyers do not have technical support to detect the size of the product, take the most common 90 degrees stainless steel elbow, divided into a variety of models
Normal R=1.5D, but many manufacturers on the market use most of the mold is 1.25D, shorter than the standard size, don't look at this 0.25D, the weight of the material but there is a difference, reduce the weight, is the manufacturer to earn more, this should be paid attention to when buying, of course, does not exclude the need to purchase special to non target.
Although most of the time after the buyer has finished the test that meets the standard, but it ignores the one hand, that is, the wall thickness of the back arc is insufficient. This is because there will be wall reduction in the elbow push system, although the caliber is barely in line with the standard, but the majority of the back is not thick enough, usually the manufacturer is relatively clear
