The spiral steel pipe is a spiral steel pipe made of steel or coils by spiral -shaped tortuous, and actively welded with both sides and welded inner seams and outer seams. For the following reasons, it can be widely used in water, electricity, chemical industry. In the production of occupations: Just change the diverse viewpoint, you can use steel pipes with a steel with steel with the same width, which is easy to adjust.
Because it is one after another, the fixed ruler length of the spiral tube is not restricted, and the length can be determined at will. The weld spiral is evenly distributed on the entire spiral tube circle, so the screw tube has a high accuracy and strong strength. It is easy to change the scale, suitable for the production of small batch and various types of spiral tubes.
The welding of the spiral steel pipe is longer than the welds of the same standard straight gap. Under the same standard wall thickness, the spiral steel pipe has the most pressure. The disadvantages of the welded seam of the spiral steel pipe are "oblique disadvantages". During the use process, the main stress direction of the steel pipe, that is, the length of the equivalent disadvantages of the steel pipe axis is smaller than that of the straight seam pipe; second, because the pipeline steel is rolled steel plates, and the pipeline steel is rolled steel plate, and the pipeline steel is rolled steel plates, and the pipeline steel is rolled steel plates, and the pipeline steel is rolled steel plates, and the pipeline steel is rolled steel plates, and the pipeline steel is rolled steel plates, and the steel plate is rolled steel plates. The impact toughness has a large opposite sex, and the CVN value in the direction of the direction of the rolling direction can be 3 times higher than the CVN value perpendicular to the rolling direction.
In order to get used to the needs of modern production, the steel structure workshop was invited. The steel structure workshop and the early component workshop have the following advantages. The production time is short, the price is low, and it is useful. Generally, the steel structure workshop contains steel pillars, steel beams, steel structure roots, steel roofs, steel roots, steel pillars have used slot steel in the past few years. In recent years, people have discovered the defects of slot steel in construction. Replace the slot steel.
The spiral steel pipes have the following advantages in the steel structure workshop. The screw steel pipe standards are strongly habitually habitually. That is to say, any standard, the spiral steel pipe can be produced, the length of the spiral steel pipe can be randomly, the maximum can be 30 meters, the spiral steel pipe can be achieved, the spiral steel pipe can It can also be made into a courses, which is better than slot steel and cheaper.
