Precautions for storing straight seam steel pipes and introduction to diameter sizes

Precautions for storing straight seam steel pipes: Most merchants do not use straight seam steel pipes quickly after purchasing them. So do we have anything to pay attention to in the storage of straight seam steel pipes? The staff of the straight seam steel pipe manufacturer reminded us that the correct storage method of straight seam steel pipes will play a good protective role and avoid many problems. First of all, we should classify and store straight seam steel pipes, so that we can avoid a lot of workloads when we need to use them. Straight-seam steel pipes will rust during storage, so we also need to separate rusty straight seam steel pipes from good straight seam steel pipes when classifying. To avoid rust, straight seam steel pipes need to be isolated from acidic and alkaline substances to avoid the influence of these substances on straight seam steel pipes. Rainwater erosion is also a cause of rust, so we'd better not store them in the open air. Humidity will also have a great impact on straight-seam steel pipes, so we need to choose a dry and ventilated place.

Series diameter size specified in the straight seam steel pipe standard:

The nominal diameter of the straight seam steel pipe refers to the series diameter size specified in the straight seam steel pipe standard. For straight seam steel pipes, pipe fittings, valves, etc., the nominal straight seam steel pipe diameter of the caliber is expressed in the series specified by the standard. The straight seam steel pipe components used for conveying fluids adopt the nominal diameter series. The nominal diameter of the Chinese straight seam steel pipe standard is expressed as an integer in millimeters (mm). The nominal diameter of the straight seam steel pipe standard is expressed in inches (in) or millimeters. When the nominal diameter of the straight seam steel pipe standard in my country is 10mm, it is marked as DN10.

The working pressure of the straight seam steel pipe refers to the pressure that the pipe, pipe fittings, valves, and other pipeline components are subjected to under normal operating conditions. The design pressure of the straight seam steel pipe refers to the pressure that the pipeline is subjected to in the combination of harsh conditions and the corresponding design temperature during normal operation. The working temperature of the straight seam steel pipe is the temperature of the pipeline under normal operating conditions, and the design temperature of the pipeline is set during normal operation. The straight seam steel pipe pipeline may withstand the corresponding design pressure.

Physical deformation of straight seam steel pipe welded steel pipe heating:

Physical deformation of straight seam steel pipe welded steel pipe heating, if a straight seam steel is welded, the size of the data can be reduced to a large extent. The demand for straight seam steel pipe projects is relatively high, and the outer seam welding starts at the beginning to ensure the penetration of the large straight seam steel pipe, the beauty of the straight seam steel pipe weld, and the continuous linearity of the straight seam steel pipe weld. In the case of severe corrosion of steel, strictly clean the edges and control the weld morphology to ensure the weld formation. The storage and transportation conditions of steel plates have an important influence on the welding of steel pipes. Severe corrosion of steel plates in the open air is inevitable, which will have a significant impact on the product.

Steel pipes can also be stacked, on the other hand, to attach lateral constraints from adjacent steel pipes; secondly, they are also supported by the support of the fixed block steel pipe below. From the above analysis, the static accumulation of steel pipes under gravity is mainly caused by the three forces of steel pipe support and horizontal binding of the upper steel pipe fixed block; but during transportation, the stress distribution of steel pipes changes under large dynamic loads. On the one hand, the steel pipe D/t (steel pipe diameter D, t steel pipe wall thickness) is relatively large, and the stress of the stacked steel pipes at the bottom of the cabin is relatively complex. The horizontal direction has been affected by the binding of adjacent pipes, and the longitudinal steel pipes are under the weight and fixed blocks, and the combined effect of the gravity of the accumulated stacked rods makes the horizontal and vertical alternation of the pipe section likely to cause warping deformation. If the steel pipe is shipped, the shorter dimension is lower, then the pressure steel pipe at the top and the adjacent pipes are required to be high.
