Introduce the main USES and steel grades used of High-pressure boiler pipe
High pressure boiler tube is mainly used to manufacture high-pressure and more pressure steam boiler pipes with high-quality carbon steel, alloy steel and heat-resistant stainless steel seamless steel pipe. These boiler tubes often work at a high temperature and high pressure. And in the role of high temperature flue gas and steam, it may occur oxidation and corrosion effects, thus requiring durable steel with high strength, high oxidation resistance, and good organizational stability. Steel grades used are: high quality carbon structural steel:20G, 20MnG, 25MnG; alloy structural steel steel:15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB etc; rust resistant steel:1Cr18Ni9,1Cr18Ni11Nb. High-pressure boiler tube in addition to guarantee chemical composition and mechanical properties, hydrostatic,flaring and flattening testing must also be done one by one.
Comprehensive Guide to ISO Steel Pipe Standards
Steel pipes are essential components in various industries, from construction and infrastructure to oil and gas. Ensuring their quality, safety, and efficiency is paramount, which is where the International Organization for Standardization (ISO) comes into play. ISO sets globally recognized standards that specify the properties and testing methods for steel pipes, providing a common language for manufacturers, suppliers, and customers. This article delves into the ISO standards for steel pipes, offering a detailed overview of their specifications and applications.
