20G seamless high-pressure boiler steel pipe is a high-quality pipe material specifically designed for high-pressure environments. Its chemical composition strictly follows the GB/T5310 standard, mainly containing carbon (0.17%~0.24%), silicon (0.17%~0.37%), and manganese (0.35%~0.65%), with phospho
In modern construction and industrial fields, the choice of pipe materials is crucial. While plastic pipes were once widely used, stainless steel pipes have gradually replaced them in recent years. What are the reasons behind this shift?From a material properties perspective, stainless steel pipes h
Seamless stainless steel pipes are widely used in various boiler equipment due to their excellent corrosion resistance, high temperature resistance, and mechanical properties. The following are some boiler equipment types that commonly use seamless stainless steel pipes:1. High-Pressure BoilersHigh-
Welding is a common connection method in steel structure construction. However, after welding, rust is prone to occur at the weld, affecting the quality and safety of the steel structure. So, how to prevent rust after welded steel pipes? Several commonly used methods are introduced below.1. Choose t
In the complex steel market, seamless stainless steel pipes, with their unique corrosion resistance, high strength, and good processing performance, are widely used in various industries such as petroleum, chemical, medical, and food. However, faced with a dazzling array of products, accurately sele
First, how is polishing stainless steel pipe fittings performed?Brightly polished stainless steel pipe fittings have a clean, shiny appearance, are easy to clean, and have an invisible protective film that prevents corrosion and scale buildup, resulting in a longer lifespan. Matte-finish brushed sta
Austenitic stainless steel is softened through solution treatment. Generally, the seamless stainless steel pipe is heated to approximately 950–1150℃ and held at that temperature for a period of time. This allows carbides and various alloying elements to fully and uniformly dissolve in the austenite.
First, the welding details for galvanized steel pipes include:1. Galvanized steel pipes with a diameter greater than 100mm should be connected using flanges or compression fittings.2. To ensure welding quality, the weld joint should be treated with galvanizing. The galvanized layer should be cleaned
Accurately measuring the length of spiral steel pipes is crucial for manufacturers. Based on years of production experience, four methods for length measurement have been summarized:1. Improved Encoder Length Measurement: This is an indirect measurement method. The length of the spiral steel pipe is
Surface quenching and tempering heat treatment for straight seam welded pipes is typically performed using induction heating or flame heating. The main technical parameters are surface hardness, localized hardness, and effective hardened layer depth. Hardness testing can be done using a Vickers hard
