The Surface Treatment And Use Of Adjusting Elbows
May 12, 2018

Adjustable elbow in the process of production due to the majority of its pipe fittings for welding, in order to improve the quality of its welding welding operations, to a certain extent will be in the end of the car into a groove, leaving a certain From the angle, with a certain edge, this requirement is also strict, the edge is thick, the angle is as much as the deviation range is stipulated. The surface quality and mechanical properties are basically the same as the tubes. For ease of welding, the fittings are the same as the steel type of the pipe being joined.

Adjustable elbow fittings are effectively treated to a certain extent by their surface treatment, so that the inner and outer surfaces of the iron oxide skin can be effectively sprayed by shot blasting and then coated with anti-corrosion paint. This is for export needs. Moreover, in order to facilitate transportation and prevent rust oxidation in the country, we must do this work.

Adjustable elbows are used for packaging when they are used. For small pipes, when they are used, for example, they need to be wooden boxes, about 1 cubic meter, and the number of elbows in such a box should not exceed one during operation. Tons, the standard allows kits, ie large sets, but the total weight cannot exceed 1 ton. For large y, a single package, like 24′′ must be a single package. The other is the packaging mark, the mark is to indicate the size, steel number, batch number, manufacturer's trademark and so on.

The adjustable elbow is widely used in chemical, hydropower, petroleum, natural gas, boiler and construction industries when it is in use. In the process of production, there will be some production processes that have the requirements and application scope of the caliber. Therefore, In order to use fair process principles and to accept necessary technological steps, due to various factors, the practical wall thickness of the floor heating pipe is generally, and under this wall thickness, all types of pipes can meet the needs of floor heating. The pressure resistance advantages of steel elbow pipes do not show up.

Adjustable elbow is mainly used for floor heating when it is in use. The demand for good thermal conductivity and low temperature thermal shock resistance is good for low temperature impact resistance. The elbow passivation process can be divided into wet and dry methods. Concrete can be divided into many types.

The passivation effect of the elbow depends on the passivation process and also depends on the stainless steel stamping elbow material itself. The factors affecting the concrete include the metallurgical structure of the stainless steel stamped elbow containing elements, stainless steel, and stainless steel processing conditions. The compositional elements, chromium, and nickel belong to the passivation intense element, iron passivation. Therefore, the higher the chromium content, the stronger the passivation of nickel and stainless steel.
