A spiral tube, also called a spiral steel tube or a spiral welded tube, is a method in which a low carbon structural steel or a low alloy structural steel strip is rolled into a tube blank at a certain angle of a helix (called a forming angle), and then the tube seam is welded. It can produce large diameter steel pipes with narrow strips.
The spiral pipe is mainly used for oil and natural gas transmission pipelines, and its specifications are expressed by the outer diameter wall thickness. The spiral pipe has single-sided welding and double-sided welding. The welded pipe shall ensure that the hydraulic pressure test, the tensile strength and the cold bending performance of the welded joint comply with the regulations.
How to increase the stability of the spiral tube?
1. Small and medium-sized steel, wire rod, steel bar, medium-diameter steel pipe, steel wire and steel wire rope, etc., can be stored in a well-ventilated shed, but must be placed on the underside.
Second, some small steel, thin steel, steel, silicon steel, small-diameter or thin-walled steel pipes, all kinds of cold-rolled, cold-drawn steel and high-priced, easy-corrosion metal products can be stored in the warehouse.
3. The site or warehouse where the spiral steel pipe products are kept shall be selected in a clean and well-drained place, away from the factories and mines that generate harmful gases or dust. Remove weeds and all debris from the site to keep the steel clean.
4. Large-scale steel, steel rails, humiliating steel plates, large-diameter steel pipes, forgings, etc. can be stacked in the open air.
5. Do not stack materials that are corrosive to steel, such as acid, alkali, salt or cement, in the warehouse. Different types of steel should be stacked separately to prevent confusion and prevent contact corrosion.
The production line of carbon spiral pipe production lines has gradually appeared in various enterprise companies and has been accepted and recognized by users. If the company wants to make the products on the production line better, it must be solved from the following aspects. If you want to produce high-quality products, you have to cooperate with the employees.
First, clean up. After the daily work is completed, the staff must clean the dust left in the workshop. If it is not cleaned in time, the staff will stay in the dust everywhere, not only will cause some damage, but also cause damage to the machine. Only when the time is cleaned can the working environment be better.
Second, the shape. There are many high-quality products on the market, and there are many waste products, mostly due to employee problems. The main reason is that some employees have not undergone rigorous training, resulting in some aspects of the product are not known, so the product department produced meets the rules. All enterprise companies can provide professional training and guidance to employees, and then conduct assessments to minimize the chance of waste.
Third, inspection. The products produced by the company must be strictly tested one by one, mark which are qualified and which are not qualified, and do not confuse them, so as to avoid unnecessary losses, which is basically what employees must know.
Through the above three aspects, the process of the carbon spiral pipe production line is also known.
