Difference between drill pipe and heavy weight drill pipe
Apr 13, 2022 read moreDifferent product uses have different requirements for welding performance. A class of tableware generally does not require welding performance, and even includes some pot enterprises. However, most products require good welding performance of raw materials, such as second-class tableware, thermos cups, steel pipes, water heaters, water dispensers, etc.
Apr 08, 2022 read moreComplete circular welds that connect pipes to ends are also known as circular welds. A true perimeter gem usually consists of multiple welds starting with a reed or stringer bead and ending with a closed weld. Belt welding is a different belt welding process that connects two pipes to the environment during the construction phase of the pipe, depending on the ease of implementation and environmental factors. It is used for perimeter welding of pipes and underground systems.

Apr 06, 2022 read moreThe purpose of the drill pipe is to transport the drilling mud to the drill bit and together with the drill bit raise, lower or rotate the bottom hole device. Drill pipe must be able to withstand enormous internal and external pressure, twisting, bending and vibration. In the process of oil and gas extraction and refining, drill pipe can be used many times.

Mar 25, 2022 read moreEpoxy powder anti-corrosion steel pipe coating is evenly and densely coated on the surface of the derusted metal pipe to isolate it from various corrosive media. It is the basic method of pipeline anti-corrosion. The pipeline is laid in the middle, and the temperature of the pipeline is increased due to the heating and transportation of oil products, which puts forward more requirements on the coating performance. Therefore, pipeline anti-corrosion coatings are increasingly using composite materials or composite structures.
Mar 22, 2022 read moreThe grades of cement mortar anti-corrosion steel pipe mortar are M3, M5, M7.5, M10, M12.5, M15, M20, M25, M30, M40. Mortar is divided into masonry, plastering and jointing according to its purpose, which has nothing to do with the label. After the cement mortar work is completed, there is an important process, that is, air drying. It means air-drying for 2-3 days in a natural state. The main purpose is to prevent the cement mortar from cracking due to bumps during shipment.
Mar 21, 2022 read more15CrMoG high-pressure alloy tube is a steel widely used in the electric power industry. It has high thermal strength when used at 500℃-550℃. When the operating temperature is higher than 550 °C, its thermal strength performance is significantly reduced. Usually 15CrMo steel is mainly used for high and medium pressure pipes and steam guide pipes with steam parameters of 510 °C, and heat exchanger tubes with a tube wall temperature of 550 °C.
