Design of Large-caliber Straight Seam Submerged Arc Welding Pipe Workshop
large-caliber straight seam submerged arc welding (SAW) pipe workshop is a kind of factory specialized in pipes production. It is a pipe production equipped with advanced products and modern facilities, which is more cost-effective and has higher production quality. This paper mainly introduces the design of large-caliber straight seam submerged arc welding pipe workshop, including the overall design requirements, the building design and layout design, the production process and quality management plan, and the requirement of environmental protection.
1.Overall design requirements
The overall design of large caliber straight seam SAW pipe workshop should meet the following requirements:
1) rational site selection: The site selection should consider the local and regional transportation and shipping environment;
2) scientific and reasonable plant layout: The main process flow, material handling technology and auxiliary facilities of the plant should be considered;
3) The plant should be equipped with advanced production equipment and complete testing methods, with quality assurance and stability;
4) The production process of large caliber straight seam SAW pipe is automated as far as possible, and the process route should be optimized reasonably;
5) Reasonable production system: System production capacity and process parameters should be considered;
6) The plant building should be built according to local building standards, fire protection, lightning protection, energy saving and other facilities, as well as sanitation, greening and employee living environment should meet the requirements.
2.Building design and layout design
1) Buildings design: The construction of large caliber straight seam SAW pipe workshop mainly includes pipe storage shed, pipe workshop, pipe workshop, pipe testing and inspection room, etc., which should fully consider the needed of production, room area and the characteristics of large-caliber pipe and other issues.
2) Layout design: The layout of large-caliber straight-seam SAW pipe workshop should meet the following requirements:
1) The plant should be laid out in the order of pipe loading, cutting, welding, inspection, testing and packaging.
2) The layout of the plant should take into account the safe passage of products and personnel entering and leaving the workshop, and the unobstacle of the materials in operation.
3) The workshop should be designed to use materials and personnel resources. People, materials, transportation and storage should be reasonably combined.
3.Production process and quality management plan
The production process of large caliber straight seam SAW pipe includes raw material loading, cutting, welding, inspection and testing, packaging and shipping. The quality management plan shall be formulated in accordance with the requirements of process flow, materials, equipment and personnel.
1) Raw material loading: This process mainly includes manual or mechanical loading, depending on production requirements;
2) Cutting: The cutting process includes manual cutting, machine cutting and other cutting techniques;
3) Welding: Different welding techniques are used, such as SAW welding, double SAW welding and SAW welding with backing;
4)Inspection and testing: This process mainly includes performance inspection, physical and chemical inspection and non-destructive inspection;
5) Packaging and shipping: According to the needs of customers, reasonable packaging and loading methods should be selected.
4.Requirement of environmental protection
The reasonable design of environmental protection should be made in large-caliber straight seam SAW pipe workshop.
1) Production process: The main purpose is to control the smoke, toxic and hazardous waste of the production process, and guarantee the air quality of the environment.
2) Plant sewage: The sewage should be treated in accordance with the requirements of state and local authorities.
3) Plant greening: Green development of the whole plant should be considered in order to make the environment more beautiful.
In conclusion, the reasonable design of large caliber straight seam SAW pipe workshop is very important for the normal operation of the enterprise and the safety of the production workers. In the design process, we should consider the overall design requirements, the building design and layout design, the production process and quality management plan, and the requirement of environmental protection.
