Thermal insulation spiral steel pipe is widely used in our daily life, and it can often be found in liquid-gas transmission network, petrochemical industry, centralized municipal engineering and so on. So, what is spirally welded steel pipe? What advantages does it have? After a series of treatment, the steel pipe processed by modern thermal insulation technology can ensure that the internal and external temperature of the steel pipe meets the requirements under complex environmental conditions and different external media, which is called thermal insulation steel pipe. two。 Semi-fixed. Generally speaking, the supervisor and the branch pipe are a fixed buried pipe, which is connected with the spiral pipe through the water distributor to transport the water to the construction site. In this form, the distance between the branch and the outlet is very large, which correspondingly reduces the number of fixed buried pipes and the investment per unit area. However, due to the frequent movement of the ground hose during irrigation, the actual working intensity of people will be relatively large, and the working environment is poor. 3. Fixed.

The insulation layer is made of rigid polyurethane foam with density from 60kg/m3 to 80kg/m3, which fully fills the gap between steel pipe and casing and has a certain bonding strength, so that a solid whole is formed among steel pipe, outer casing and insulation layer. Polyurethane directly buried thermal insulation pipe foam has good mechanical properties and thermal insulation properties, usually can withstand temperature 120 ℃ through modification or combination with other thermal insulation materials can withstand 180 ℃. The structural design of the new polyurethane foamed thermal insulation steel pipe is novel, and the insulation work of the joint is carried out on the site of the polyurethane foamed thermal insulation steel pipe project, including the installation of the joint outer casing, the connection and sealing between the joint outer casing and the supervisor, and the foaming work of the on-site joint, but it does not include the welding of the joint part of the steel pipe.

Thermal insulation materials are used for all kinds of cold water, cold air, cold oil pipeline round, special-shaped and any shape of pipe heat preservation. Prevent condensation: polyethylene foam pipe material is a closed-cell structure, which is adiabatic by the gas insulation in the closed cell rather than polyethylene material. It has excellent resistance to water vapor penetration. Therefore, it is necessary to introduce supervisors for pipeline construction projects and anti-corrosion overhaul projects, and supervision, like the roles of design, construction and overhaul, should have the ability to grasp professional anti-corrosion standards. All aspects of pipeline engineering should pay enough attention to anticorrosion, a seemingly unimportant covert project. Features of centrifugal glass wool products: ◆ inner steel pipe adopts silicone high temperature resistant paint (≥ 400℃) anticorrosive coating to effectively prevent working steel pipe from corrosion and prolong service life.

1. Ground Crew Supervisor: Experienced baggage handlers may be promoted to a supervisory role, overseeing a team of handlers and ensuring smooth coordination between different airport departments.

The structural tube core– the insulation layer of seamless steel pipe for conveying fluid– adopts polyurethane rigid foam, which is closed, so it has good thermal insulation, low water absorption and low thermal conductivity. The bonding strength with the steel pipe is higher than the tensile strength of the foam itself, so it also plays an anti-corrosion effect on the steel pipe.

The joint installation company may send personnel to the project site to carry out the heat preservation work of the joint, including the installation of the outer casing of the joint, the connection and sealing of the outer casing of the joint with the supervisor and the foaming of the on-site joint, but it does not include the welding of the steel pipe of the joint part, (1) sleeve joint, in which the joint casing is made of the same material as the prefabricated insulation pipe casing.

Carry out supervision work in an all-round way and run the winter supervision mode ahead of schedule. Centering on the content of “eight precautions and one prohibition”, Changqing Supervision Company makes a typical accident display board for winter construction from three aspects: accident process, cause analysis and preventive measures. Carry out winter prevention and thermal insulation material reserves, key parts of thermal insulation, as well as anti-collision crane and well control equipment pipelines, gates, instruments of the integrity of the special inspection, omni-directional pulse. At the same time, upgrade supervision, require all supervisors to inspect more, strictly stand by, attach importance to education, urge the post staff to strictly implement the winter operation rules, keep a close eye on the key links of winter construction, zero tolerance for hidden accidents, and ensure safe production.
