SSAW Pipe

 Straightening is an important process in the production of LSAW steel pipes. Especially for oil casing and oil and gas pipes of API standard with high quality requirements, special pipes for machinery and equipment.These kinds of steel pipes not only have strict requirements on the steel grade and weld quality, but also have high requirements on the straightness of the steel pipes.Because the deviation of straightness is directly related to the processing and connection of the pipe end thread and pipe hoop of the oil casing and conveying pipe, as well as the distortion and deformation during the use of the pipeline. There are two processing forms of pipe end threading - pipe rotation and tool rotation. Most of the threading processing adopts the method of pipe rotation, which requires higher straightness of the steel pipe. Affected by the internal stress of the steel pipe, the thermal influence of the welding seam, the eccentricity during forming, the tightening pressure, and the ...

Due to the chaos of global shipping in recent years, the congestion situation of various ports is very serious. As a result...

 The anti-corrosion coating of seamless steel pipe refers to the use of paint to uniformly and densely coat the surface of the rust-removed steel pipe to isolate it from various corrosive media. It is one of the most basic methods for anti-corrosion of seamless pipes. There are many kinds of anti-corrosion coatings, and their properties and uses are different. Among them, the coating technology is to form a continuous covering layer of insulating material on the metal surface to insulate the metal and the electrolyte in direct contact with it.That is to set a high resistance so that the electrochemical reaction cannot occur normally. Seamless steel pipes means pipes with hollow sections and are used in large quantities for conveying fluids.When transporting oil, natural gas, gas, water and some solid materials, seamless pipes are often affected by external factors such as geological conditions and weather conditions and corrode. Therefore, it is necessary to carry out anti-corrosio...

 Pipeline transportation is a method of transporting liquid and gas materials over a long distance using pipelines as a means of transportation. special components. Sometimes a pneumatic tube can do a similar job, transporting solid tanks with compressed gas while the cargo is inside. In recent years, the pipelines used for fluid transportation are mainly seamless pipes, and gas is mostly used for welded pipes. Shipping petroleum products by pipeline is more expensive than shipping by water, but still cheaper than shipping by rail. Most pipelines are used by their owners to transport their own products. Advantages of pipeline transportation: (1) The shipping volume is large. An oil pipeline can continuously complete the transportation task. According to the size of its pipe diameter, its annual transportation volume can reach millions of tons to tens of millions of tons, or even more than 100 million tons. (2) Small footprint. The transportation pipelines are usually buried undergr...

Project location：France Product：SSAW steel pipe Standard and material：EN10219 S355JR Specifications：914mmX 20mm Usage：Marine Piling Project Inquiry time：2022-01-15 Order time：2022-03-25 Shipping time：2022-5-25 Arrival time：2022-07-06 I met this French customer in 2018. The customer visited the factory twice, and was very satisfied with the equipment, professionalism and management of the factory, and placed orders for Xinyue in the next few years. This order is for 914 pile pipes, with a total of more than 400 tons. As it is a marine pile pipe project, the outer surface of the steel pipe needs Hempel’s epoxy coating and the shipment also needs to be very professional and careful. After more than 1 month of production, all the coated pipes have been produced and passed the comprehensive inspection by a third party. Considering the fragility of the coated pipe, the packaging is factory-installed. Each pipe has been added with 8 cloth ropes and the pipe ends are equipped with slings. At t...

 In the hot and hot weather in summer, there is a lot of rain, and the weather is more hot and humid after the rain. In this state, the surface of galvanized products is prone to anti-alkali (commonly known as white rust) phenomenon. If the plated goods are not picked up in time, if they are not unpacked and used in time when they arrive at the destination, the phenomenon of anti-alkali will easily occur to prevent irresistible losses. The service life of galvanized steel pipe is generally 8-12 years, with an average service life of 10 years, and it can be extended in dry environment. In rainy and foggy weather, try to store or cover indoors as much as possible. After the rain stops and fog is dispersed, the sheet should be removed to keep it ventilated and dry; avoid direct contact with wet soil when stacking. Treatment methods for galvanized products entering water and damp: 1. If the whole piece is exposed to water, it should be disassembled immediately and placed in a ventilate...

 Common steel defects and related terms are introduced by seamless pipe manufacturers as follows: 1. Roundness: the circular section of the rolled material, such as the cross section of round steel and round steel pipe, the degree of diameter difference in each direction 2. Due to unreasonable mold design or manufacture, improper extrusion process, mold and extrusion cylinder, lubrication, etc., the metal flow velocity difference at each point is too large, resulting in deformation of the profile, due to excessive internal stress or traction force. Excessive size leads to dimensional deviation of profile tensioning 3. Bending: the degree to which the rolling piece is not straight in the length or width direction, and is curved 4. Sickle bending: the phenomenon that the length direction of the steel plate (or steel strip) bends to one side on the horizontal plane 5. Curvature of gourd and scoop: The steel plate (or steel strip) has undulations in the length or width direction at the...
