1. Since the shrinkage of stainless steel pipe fitting casting is much greater than that of cast iron, to prevent shrinkage cavities and shrinkage porosity defects in castings, measures such as risers,...
Plastic-coated steel pipes, also known as plastic-coated pipes, steel-plastic composite pipes, and plastic-coated composite steel pipes, are based on steel pipes. A layer of plastic anti-corrosion layer...
Oil casing is a large-diameter pipe that plays a role in fixing the walls or wellbore of oil and natural gas wells. The casing is inserted into the wellbore and fixed with cement to help the wellbore...
Coating anti-corrosion is a unifrm and dense coating formed on the surface of rust-removed metal pipes. The coating can isolate it from various corrosive media. Steel pipe anti-corrosion coatings increasingly...
To protect power and communication cables laid in system fields such as railways, highways, subways, and municipal construction, cable protection tubes are generally added to the pipelines when the cables...
There are two possibilities for the formation of surface defects of spiral steel pipes: one is that the material itself is not plastic in the process of deformation, resulting in cracks and outward folding;...
1. Improved encoder length measurement This method is an indirect measurement method. The length of the steel pipe is measured indirectly by measuring the distance between the two end faces of the steel...
1) Storage and transportation of steel pipelines All kinds of steel pipes should generally be concentrated in a site that is a certain distance away from the construction road. When storing the pipe,...
Straight seam steel pipe is a welding process of steel pipe opposite to spiral steel pipe. Because the welding process of this kind of steel pipe is relatively simple, and the welding cost is relatively...
1. Production method: Stainless steel welded pipes are divided into two categories: seamless pipes and welded pipes according to the production method. Seamless steel pipes can be divided into hot-rolled...
1. Fixed-length spiral steel pipes do not need to be bundled. 2. If the ends of the spiral steel pipe are threaded, they should be protected by thread protectors. Apply lubricant or anti-rust agent to...
1. The infrastructure cost is low. Compared with railway transportation, the infrastructure cost can be saved by three points, while the transportation volume is twice that of the railway. 2. The construction...
Steel pipeline corrosion is mainly divided into two categories: internal corrosion and external corrosion. External corrosion is mainly caused by corrosion caused by the connection between the pipeline...
Stainless steel pipes are safe, reliable, hygienic, environmentally friendly, and economical. The thin-walled pipes and the successful development of new, reliable, simple, and convenient connection methods...
With the development of the construction industry, the application of welded pipe machinery in construction projects is becoming more and more extensive. As an important industrial equipment, the procurement...
Feature 1: Higher accuracy Precision carbon steel pipes have high processing accuracy and can be used to manufacture high-precision mechanical parts. This is because the production and processing of precision...
Seamless tubes (SMLS) are cut into sections by steel mills, and then heated in an annular furnace perforated-sizing straightening cooling- cutting- packed to become qualified finished products, which...
The stress on the API 5CT oil casing in the oil well: to ensure that the casing running into the well is continuous, not cracked or deformed, the casing is required to have a certain strength, enough...
There are six main processing methods for seamless pipes (SMLS): 1. Forging method: Use a swage forging machine to stretch the end or part of the pipe to reduce the outer diameter. Commonly used swage...
