  ASTM A252 LSAW Steel Pipe for Structural Piling Projects

  The production process of LSAW steel pipe is flexible, and it can produce any specifications and wall thickness within the product range. The production efficiency is lower than that of high-frequency straight seam welded steel pipe SSAW steel pipe. The biggest advantage of LSAW pipe is that it can produce high-frequency steel pipe, spiral steel pipe, and even specifications and models that seamless steel pipe cannot produce. The production cost of straight seam submerged arc welded pipe is higher than that of high-frequency steel pipe and spiral steel pipe, but there is a large price discount space compared with seamless steel pipe. Its standards include ASTM A252, API 5L, GB/T3091, EN10219, EN10210, EN10217, etc. Today we focus on ASTM A252 LSAW steel pipe.

  How to Choose the Right Boiler Tube

  Recently, the third 750MW unit of the Bellary Thermal Power Station (BTPS) in India was forced to shut down for three days due to boiler tube leakage and other technical problems. This incident not only impacted the local power supply, but also once again aroused the industry's high attention to the selection and quality of boiler tubes. As a key component in thermal equipment, the performance of boiler tubes directly determines the stability and safety of equipment operation. So, in the face of a wide variety of boiler tube products, how should users scientifically select and avoid potential risks?

  What is insulated steel pipe?

  Insulated steel pipe is a pipe used to transport liquids and gases while maintaining a stable temperature inside the pipe. It is usually composed of a steel pipe and internal insulation materials, which can prevent the temperature of the liquid or gas in the pipe from changing during transportation due to the influence of the external environment. Insulated steel pipes can be used in heating, refrigeration, chemical industry, petroleum and other fields, which can effectively reduce energy consumption and environmental pollution.

  The use of hot-dip galvanized rectangular tube

  Galvanized rectangular pipe, to put it bluntly, is to coat the surface of ordinary steel pipe with a layer of zinc. You know zinc is not the kind of metal that is a little silvery white, it prevents the steel pipe from rusting. This step of galvanizing is like putting on a "armor" on the steel pipe, so that it is not so easy to "get sick" in the wind and sun. If there is no protection of zinc, the "metal guy" of steel will be easily soaked by rain, and it will immediately rust and corrode, and even rot after a long time. Galvanized rectangular pipes are particularly suitable for use in the construction field, because it not only ensures that the steel is strong and durable, but also looks good, like wearing anti-rust clothing, which is both beautiful and practical.

  Hot-Rolled vs Cold-Rolled Square Tubes Explained

  Hot-rolled square tubes and cold-rolled square tubes are the forming processes of steel or steel plates. They have a great influence on the organization and properties of steel. The rolling of steel is mainly hot rolling, and cold rolling is only used to produce small steel and thin plates.

  Comparison Between API 5CT J55 and L80 Pup Joints

  J55 and L80 are API 5CT standard petroleum casing steel grades used in the oil and gas industry. J55 is a lower strength steel grade, while L80 is a higher strength and better corrosion resistance steel grade, usually used in more challenging well conditions.API 5CT J55 is a common pup joint grade with medium strength and good toughness. L80 nipple belongs to the higher strength steel grade in API 5CT.

  Application and advantages of ASTM A105 slip-on flange

  Plate flat weld flanges are suitable for connecting steel pipes with a nominal pressure not exceeding 2.5MPa. The sealing surface of a flat weld flange can be made into three types: full plane, concave and convex, and tongue and groove. The neck height of a necked flat weld flange is relatively low, which improves the rigidity and bearing capacity of the flange. Compared with butt weld flanges, the welding workload is large, the consumption of welding rods is high, and it cannot withstand high temperature and high pressure, repeated bending and temperature fluctuations, but it is more convenient to install on site, and the process of beating and rubbing the weld can be omitted, so it is more popular.
