Engineering and Safety of Thick Wall Steel Pipe

Engineering regulations
Welding thick-walled steel pipe, whose main product includes ASTM A53 carbon steel pipe. When actually selecting or using thick-walled pipe fittings, you must first comply with the provisions in the relevant laws and regulations, especially where extremely or highly hazardous fluid media, flammable media, and high-pressure gases are transported. Under this premise, the types of pipe fittings are mainly determined according to the application and use conditions (pressure, temperature, fluid medium). The relevant regulations/specifications are mainly listed below for reference only.
a. Special Equipment Safety Supervision Law;
b. Special equipment safety inspection regulations are listed;
c. Pressure pipeline safety management and supervision regulations;
d. Regulations on quality supervision and safety supervision of special equipment;
e. Special equipment design/manufacturing/installation supervision and management regulations (preparation);
f. Pressure pipeline safety technical supervision regulations (preparation);
g. Industrial metal pipeline safety technical specifications (preparation);

Safety and economy
In addition to the above-mentioned introduction, there are many other types of structure of pipe fittings used in the actual piping engineering to meet the requirements of various working conditions, especially the special working conditions. In engineering design or selection, the higher the strength level of the pipe fittings, the higher the safety, but the greater the cost of the project, will cause unnecessary waste.
Considering the economic benefits, while meeting the engineering design requirements and reducing the cost as much as possible, it is often easy to form the result of a small number of varieties on the selected pipe fittings, which is not conducive to the management, regulation and design changes of the construction materials on site. Material substitution, etc. Therefore, the selection of pipe fittings should integrate safety and economy, and it is appropriate to reduce the variety of pipe fittings as much as possible. In addition, the conditions of on-site construction, the level of construction, the purchase cycle of pipe fittings and other factors should also arouse the necessary attention in the selection of pipe fittings. In specific circumstances, the possibility of using on-site
bending of reinforced pipe joints, miter bends and small-diameter pipes should also be considered.
At the same time, it is necessary to understand the market supply situation of the production capacity and products of the pipe fitting factory.
