  Seamless steel pipes for oil extraction

  Seamless steel pipes (SMLS) play a vital role in oil extraction and are considered one of the core pipe materials in the petroleum industry. In modern oilfield operations, nearly all critical downhole components that must withstand high pressure are made from seamless pipes. Their superior strength, durability, and ability to handle extreme conditions without weld seams make them indispensable for drilling, oil and gas transportation, and offshore platform construction.

  How to store 304 stainless steel pipes?

  304 stainless steel pipes are known for their strength and corrosion resistance, but they are not completely rust-proof. Improper handling or poor storage conditions can still lead to rust spots. With proper protection and storage practices, however, these pipes can remain in excellent condition for many years. This article will briefly introduce how to store 304 stainless steel pipes.

  25MnG high-pressure boiler steel tubes

  SA-210C (25MnG) is a seamless carbon-manganese steel tube specified under the ASME SA-210 standard, designed primarily for use in boilers and superheaters. As a pearlitic heat-resistant steel, it offers an excellent balance of strength, ductility, and thermal stability. In 1995, China incorporated this material into the GB5310 standard under the designation 25MnG, refining its chemical limits to enhance weldability and structural stability. By controlling carbon content (≤0.30%) and increasing manganese levels, 25MnG achieves superior mechanical strength while maintaining good plasticity, making it a core material for high-pressure boiler applications.

  Global standards for boiler tubes

  Boiler tubes are essential components used in the manufacture of superheaters, reheaters, water walls, and economizers for supercritical and ultra-supercritical boilers. These tubes are required to operate under high temperature and high pressure for extended periods, demanding exceptional creep strength, oxidation resistance, corrosion resistance, and structural stability to ensure long-term reliability in power generation and industrial processes.
