Product Description

20G Seamless Steel Pipe is a specialized high-quality carbon steel pipe designed specifically for high-pressure boiler applications. The designation "20G" refers to its material grade: "20" indicates a carbon content of approximately 0.20%, while "G" stands for "Boiler" (from the Chinese Pinyin Guōlú). Manufactured in strict accordance with the GB 5310 standard, this pipe is engineered to withstand high temperatures and high pressures, making it a critical component in power generation and heavy industrial systems. Unlike standard structural pipes, 20G seamless pipe undergoes rigorous heat treatment and testing to ensure stability under thermal stress.

Features & Advantages

• High-Temperature Resistance: Specially formulated to maintain mechanical strength and structural integrity even when exposed to temperatures up to 450°C, preventing deformation under heat.

• High-Pressure Durability: Possesses excellent bursting strength and creep resistance, essential for safety in high-pressure steam environments.

• Superior Weldability: The low carbon content ensures excellent welding performance, reducing the risk of cracks during the installation of complex boiler piping networks.

• Strict Quality Control: Each pipe undergoes 100% non-destructive testing (such as ultrasonic or eddy current testing) and hydraulic pressure tests to guarantee zero defects.

• Good Plasticity: Capable of bending and flaring without cracking, facilitating easier installation in tight boiler spaces.

Product Applications

• High-Pressure Boilers: The primary material for water wall tubes, superheater tubes, and economizer tubes in thermal power plants.

• Steam Piping: Used for main steam pipelines and high-pressure steam transport in industrial settings.

• Heat Exchangers: Ideal for tubes in heat exchangers that operate under high pressure and temperature.

• Petroleum & Chemical: Suitable for high-pressure fluid transport in refineries and chemical plants where temperature stability is required.

• Power Generation: Essential for sub-critical and supercritical boiler units in electricity generation facilities.
