Construction Large diameter High Strength 0.8 - 12.75 mm Hot Rolled Spiral Welded Round Carbon Steel Pipe

Product Advantages
01.Anticorrosive:17 years in heavy industrial areas.
02.Cheap:The cost of hot-dip galvanizing is lower than that of other coatings.
03.Reliable:The zinc coating is metallurgically bonded to the steel and forms part of the steel surface,so the coating is more durable.
04.Strong toughness:The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
05.Comprehensive protection:Every part of the plated piece can be galvanized,and is fully protected even in depressions,sharp corners,and hidden places.
06.Save time and energy:Galvanizing process is faster than other coating methods.

It is made by rolling low-carbon carbon structural steel or low-alloy structural steel strip according to a certain spiral angle
(called forming angle) into a tube blank, and then welding the tube seam together. It can be made with a narrower Strip steel
produces large diameter steel pipes. Its specifications are expressed by outer diameter * wall thickness, and the welded pipe
shall be ensured that the hydraulic test, the tensile strength of the weld and the cold bending performance must meet the
requirements.
