Precision cast steelThere are many types of elbows, and there are also many application environments and contact materials. The key to the length of the service life of the pipe lies in its anti-aging ability. Due to the influence of materials, the actual effect of anti-aging of some pipelines is likely to be insignificant. The following methods can complete the anti-aging of pipelines.

1. In the paving process, it is critical to overcome the axial deformation caused by the periodic temperature difference and manipulate the thermal expansion.

2. When the hot-melt arc welding pipe is connected with the metal hose and the cement pressure pipe, the precision cast steel elbow should be adhered firmly to prevent the change of the axial force due to the temperature change of the material, which will affect the sealing performance ; The circular laying of hot-melt electric-melt pipe fittings is within the planning allowable range, which can meet the needs of pipeline temperature transformation.

3. Able to use blue tube or black tube to extrude blue ribbon. The latter one usually has stronger anti-ultraviolet light and anti-aging properties, and it is also recommended that the protective shell be used by the masses. The pipeline should be protected from the sun during the transportation and storage period, and the on-site placement time should be very short.

Therefore, customers should also avoid pipeline embrittlement as much as possible when applying precision cast steel elbows. For example, prevent direct sunlight, use corrosion-resistant tape to encapsulate the pipeline, etc., to maintain the service life of the pipeline.

What is the production process of the straight seam steel pipe and the elbow pipe?

If the straight seam steel pipe is to be made into a precision cast steel elbow, a mold with supporting facilities is required. Naturally used molds should be selected according to the manufacturing process. If you want to bend the straight seam steel pipe into a elbow, you can usually choose two processing techniques, one is the hot bending process and the other is the cold bending process. Hot bending needs to manipulate the temperature of the elbow, when the temperature reaches a certain level, the straight seam steel pipe can be bent. The cold bending process is the use of mechanical equipment to bend straight seam steel pipes directly at room temperature. The advantages and disadvantages of these two processing techniques are different, so the performance of the finished bend is also very different.
