LSAW Steel Pipe

 　　Upset tubing, as the name suggests, is to thicken the tubing to make the tubing more robust and durable. The thickness of a standard pipe is not increased randomly. Increasing randomly may cause cracks or brittle fractures due to changes in the stress structure of the pipe body. Any thickening of the tubing must be thickened after in-depth research and design verification. 　　In offshore oil, many buried submarine pipelines are immersed in seawater for a long time, and are subject to the impact of seabed sediment and huge seawater to produce various erosions and impacts, which will cause great damage to the external pipe wall and shorten its life. Inside the oil pipeline, complex crude oil with high temperature, high heat, high corrosion, oil, gas and water combination is transported at a relatively fast speed. Long-term transportation will cause different degrees of corrosion or perforation in the inner pipe, making it difficult to repair the crude oil leakage, which makes it di...

    Marine natural gas must be transported by offshore pipelines, and crude oil produced in shallow water can be directly loaded into tankers by production platforms. However, the crude oil produced in the deep sea, the large oil tanker docking on the production platform will threaten the platform safety, so there is a single point mooring in the sea dedicated to docking large oil tankers. In this way, there must be an oil pipeline connecting the production platforms to a single point mooring.     The marine pipeline laying operation is developed by the construction method of land pipelines crossing rivers and lakes. There are three main methods of pipe laying: pipe laying, towing, and drum boat laying. Which operation method is selected depends on the diameter of the pipe, the depth of the seawater, the sea conditions, and the distance from the shore.     ① Pipelaying vessel laying     This is the most commonly used method. The operation p...

　　The oil industry is an industry that uses a large number of oil pipes . Oil pipes play an important role in the oil industry: 　　1. The oil pipe has a large amount of consumption and spends a lot of money, and has great potential for saving expenses and reducing costs. The consumption of oil well pipes can be calculated based on the annual drilling scale. According to the specific conditions of China, 62kg of oil well pipe is required for every 1m drilled, including 48kg casing and 10kg oil pipe. Drill pipe 3kg, drill collar 0.5kg; 　　2. The mechanics and environmental behavior of petroleum pipelines have an important impact on the adoption of advanced technologies and increased production and efficiency in the petroleum industry; 　　3. The loss of oil pipe failure is huge, and its safety, reliability and service life are of great importance to the petroleum industry. 　　Different types of casing used in oil extraction: Surface oil casing protects the well from contamination by s...

　　The API standard is short for the American Petroleum Institute. It is one of the production standards for oil pipeline steel pipes. It also includes API5L ASME A53 and some other standards. 　　The oil casing is an important equipment for oil drilling. Its main equipment also includes drill pipe , core pipe and casing, drill collar and steel pipe for small diameter drilling. 　　Tubing specifications: 8-1240 × 1-200mm 　　Standard: 　　API SPEC 5CT - American Petroleum Institute Standard 　　SYT 6194-2003 — Oil and gas industry, oil and gas well casing or tubing for oil pipe 　　Use: Pipes that are used in production or liquid injection 　　The main production of steel pipe grade: J55, K55, N80, L80, P110, etc. 　　Tubing classification: non-thickening tubing (NU), outer thickening tubing (EU), integral joint tubing (IJ) 　　In the API5CT, the casing and tubing are divided into 4 groups and 19 steel grades. According to the manufacturing method, it is divided into two categories: sea...
