Thick wall coiled pipe is a kind of familiar steel. It is widely used in construction and pipeline industry because of its durable performance and excellent quality. Have we known about the packaging process of the frequently used steel? With the development of domestic economic situation and the acceleration of welding and casting trend, the advantages of NC cutting are gradually recognized. NC cutting not only greatly improves the rate of plate and product quality, but also improves the working environment and labor efficiency. At present, the NC cutting machines used in the thick wall coil processing industry are mainly flame and ordinary plasma cutting machines, but pure flame cutting can not meet the needs of modern production. At present, most NC cutting machines are NC plasma cutting machines. This type of cutting machine can meet the needs of thick wall coiled pipe plate processing and thick wall coiled pipe parts processing, so the demand will be greater and greater, but there is still a very obvious gap with foreign countries, which is mainly reflected in: 90% of the developed thick wall coiled pipe processing industry is digital control cutting machine, and only 10% is manual cutting; The CNC cutting machine only accounts for part of the total blanking. 10%, of which the proportion of NC plasma cutting is small. Professional hot rolled steel pipe, large diameter thick wall rolling pipe, thick wall straight seam rolling pipe, steel casing, rolling pipe factory to ensure quality, service and quality. Your satisfaction is our pursuit! Welcome to inquire. In industrial production, thick wall coil thermal cutting generally includes gas cutting, plasma cutting laser cutting, etc. Among them, plasma cutting has a wider cutting range than gas cutting More efficient. Fine plasma cutting technology is close to laser cutting in material cutting surface quality, but the cost is much lower than laser cutting. Therefore since the successful development of the United States in the mid-1950s, plasma cutting has developed rapidly. With the rapid development of computer and digital technology, NC cutting is also developing, which improves the machining accuracy. Save materials
.The pipeline installation sequence shall be adopted according to the principle of zoning and subsystem. First the lower level, then the upper level, and then the difficulty. In principle, the pipes connected to the machine are arranged from inside to outside to reduce the impact of welding stress on the installation accuracy of the machine.

Jia Qifeng, manager of the Department, welcomes you at any time!.
The longitudinal weld of the same barrel part of the coiled pipe shall not be greater than 2.
Installation requirements.In addition, when the pipe rolling equipment is made, we should not have more than two longitudinal welds on the same cylinder section of the pipe rolling. For long-term pipe rolling, Q235B pipe rolling, Q345B pipe rolling, large-diameter thin-wall pipe rolling, large-diameter thick wall pipe rolling, stainless steel pipe rolling, L360 pipe rolling and 16Mn pipe rolling, the products are complete, the quality is excellent and the price is favorable. The distance between the two longitudinal welds should not be less than 200.
Since the groove sizes of longitudinal and circumferential joints of hot-rolled pipes are different, it is necessary to confirm whether the inner side is upward before plate rolling to ensure the correctness of groove direction.
The distance between the two longitudinal slits of the reel assembly shall be greater than 100mm. The distance between the outer wall of the branch pipe and the weld shall not be less than 50mm.
The continuous pipe has good characteristics and performance in use, and advanced technology is adopted. If we want to make progress and enhance competitiveness, we must have a good opportunity at present. Just like the development of the iron and steel industry, although the pipe rolling industry has made remarkable achievements in recent years, accounting for more than 1 / 4 of the world's output, there is still a certain gap with the international advanced level in terms of technical equipment, product quality and product grade, enterprise economic scale and main technical and economic indicators. The coil adopts PLC automatic system, and each part is operated on the panel. The cutting length of winding tube adopts photoelectric induction, accurate positioning and automatic cutting. Each process adopts double pump oil pressure system to ensure stable operation. The pipe rolling has different application ranges: winding pipe length: 0-1400mm winding pipe thickness: 2-15mm, purpose: 3 inches x24x winding pipe diameter: 20-200mm, working voltage: 380V, 50Hz. It can be used according to the specified parameters and scope, so as to ensure that it can play an important role and value in use. Large coil is durable, stable and easy to operate. The packaging process of coil includes filling, packaging, sealing and other main processes, as well as relevant pre and post processes such as cleaning, stacking and disassembly. In addition, the rolling process also includes measuring or stamping on the package. Using mechanical packaging products can improve productivity reduce labor intensity, meet the needs of large-scale production and meet the requirements of cleanliness and hygiene. With the emergence of new packaging materials and the continuous innovation of packaging technology, spiral pipe can play an important role and value in different industries and fields.
