Precautions for storing straight seam steel pipes:
Most merchants did not use it soon after purchasing straight seam steel pipes. So do we need to pay attention to the storage of straight seam steel pipes? The staff of straight seam steel pipe manufacturers is reminded that how to store straight seam steel pipes correctly will play a very good role in the protection and avoid many problems. First of all, we need to classify and store straight seam steel pipes, so that we can avoid a lot of work when we need to use them. Straight seam steel pipes will rust during storage, so we also need to separate rusted straight seam steel pipes from good straight seam steel pipes when sorting. To avoid corrosion, the straight seam steel pipe needs to be isolated from acid and alkali substances, to avoid the influence of these substances on the straight seam steel pipe. The erosion of rainwater is also the cause of the corrosion, so we had better not store it 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. The staff of the automobile tire manufacturer reminded us that there should be a cushion layer under the straight seam steel pipe to isolate the wet ground.

The series of diameters specified in the standard for straight seam steel pipes:
The nominal diameter of straight seam steel pipe refers to the series of diameters specified in the standard for straight seam steel pipes. For straight seam steel pipes, pipe fittings, valves, etc., the nominal straight seam steel pipe diameter is represented by the series specified in the standard. The components of straight seam steel pipes used for transporting fluid adopt the nominal diameter series. China's straight seam steel pipe standards use nominal diameters expressed as integers in millimeters (mm). See the chapter "Basic Knowledge of Straight Seam Steel Pipe Pressure Vessels" in this book.

The nominal diameter of the straight seam steel pipe standard is expressed in inches (in) or millimeters. When the nominal diameter of my country's straight seam steel pipe standard is 10mm, it is marked as DNIO. The working pressure of straight seam steel pipe refers to the pressure that pipes, pipe fittings, valves, and other pipeline components bear under normal operating conditions. The design pressure of straight seam steel pipe refers to the pressure that the pipeline is subjected to under severe conditions in combination with the corresponding design temperature during normal operation. The working temperature of a straight seam steel pipe is the temperature of the pipe under normal operating conditions, and the design temperature of the pipe during normal operation is the set straight seam steel pipe that may withstand the corresponding design pressure.

Straight seam steel pipe welded steel pipe heating physical deformation:
Straight seam steel pipe welding physical deformation of steel pipe heating, a straight seam welded steel welding, can reduce the size of the data to a large extent the physical deformation of straight seam steel pipe. The demand for straight seam steel pipe projects is high, and the first start of outer seam welding is to ensure the penetration of large straight seam welded steel pipes, the appearance of straight seam steel pipe welds, and the continuous linearity of straight seam steel pipe welds. In the case of severe corrosion of steel, the edge should be cleaned strictly, and the shape of the weld seam should be controlled to ensure the perfect weld seam shape. The storage and transportation conditions of the steel plate have an important impact on the welding of steel pipes. Severe corrosion of the steel plate in the open air is inevitable and will have a significant impact on the product.

The steel pipes can also be superimposed, on the other hand, with additional lateral restraint from adjacent steel pipes; secondly also supported by the following, fixed block steel pipe supports. From the above analysis, the static accumulation of the steel pipe under gravity is mainly caused by three forces: the steel pipe support of the upper steel pipe fixing block and the horizontal binding; but during the transportation process, the stress distribution of the steel pipe changes under a large dynamic load. On the one hand, the steel pipe D/t (the steel pipe diameter D, t steel pipe wall thickness) is relatively large, the stress of stacked steel pipes located at the bottom of the engine room is relatively complex, and the horizontal direction has been affected by the binding of adjacent pipes. The combined effect of the gravity force of the piled rods also makes the horizontal and vertical alternation of the pipe section possible to be warped and deformed. If the steel pipes are shipped with the shorter dimensions lower by mistake, then the requirements for the top and adjacent penstock steel pipes are higher.
