EN10305-1 E235 25*1.5 White Zinc Precision Seamless Steel Pipe For Screw Compressor Air Compressor Pipeline
Galvanized with EN10305-1 E235 high-brightness precision seamless steel pipe, the outer surface of the
steel pipe can begalvanized, with a length of 6 meters or 6 meters, or according to customer requirements,
the inner and outer surfaces of the steel pipe can be galvanized at the same time, with a length of 3 meters
or within 3 meters. , Generally, the thickness of galvanizing is 8~25μm, the steel pipe has good corrosion
resistance, and the salt spray test can reach 250 hours. Because the steel pipe is processed by normalizing
heat treatment, it can be as tough as copper pipe, and can be bent or flared. It is especially suitable for replacing
copper pipes in the air compressor industry.Main use: air compressor pipeline, users who have high requirements
on the anti-rust and anti-corrosion of the inner and outer walls of the steel pipe.
