The cylinder refers to the cylindrical metal parts that guide the piston in a straight reciprocating motion in the cylinder. The air in the engine cylinder expands to convert heat into mechanical energy; The gas is compressed by the piston in the compressor cylinder and the pressure is raised.
1. The surface of large-diameter steel pipes is more durable and has anti-rust and anti-rust treatment. The oxidation rate will not be too fast and white rust will not form on the square steel pipe.2. It has anti-corrosion and wear-resistant properties, making the seamless steel pipe have a longer service life.3. Seamless steel pipes are protected. After heating, hot-dip galvanizing is performed on each position of the seamless steel pipe, and the convex and concave positions are protected.4. Because the seamless steel pipe is hot-dip galvanized on the outside, it saves the time of painting or brushing, making the construction more convenient.5. Hot-dip galvanized steel pipes will not freeze or break even within 39 days, making them very suitable for northern regions.| Speci -cation | Grade | Chemical Composition [%] | ||||||||||||||
