Qilu machinery large superheater manufacturing will be completed
Galvanization is the leading method to protect metals from environmental elements that cause corrosion, rust, and the eventual weakening of the steel. Hot-dip galvanizing deposits a thick, robust layer of zinc iron alloys on the surface of a steel item. When exposed to the atmosphere, pure zinc reacts with oxygen to form zinc oxide which further reacts with carbon dioxide to form zinc carbonate. A dull, grey, fairly strong material that stops further corrosion in most circumstances, protecting the steel from the elements. Galvanized steel is widely used in applications where rust resistance is needed. Galvanized steel can be welded however, you should exercise caution around the resulting fumes. Galvanized steel is commonly used in the automotive industry to enhance the corrosion performance of exterior body parts. Galvanized Steel is magnetic.

This large superheater weighs more than 230 tons, with a total length of 27 meters and a diameter of 3.8 meters. Among them, the deep hole butt welding and deep hole lap welding used for 2,830 heat exchange tubes and tube plate welding are world advanced welding techniques. Qilu Machinery Co., Ltd., which once successfully manufactured the first and second dehydrogenation reactors for Qilu petrochemical ethylene plants and mastered the new welding technology, has successfully become the preferred partner of Litz company. By October 17th, the deep-hole butt welding of 2,830 tubes and tube sheets had been completed. After passing the coloring and gas-tight test, the welding pass rate reached 100%. In addition, more than 2,300 lap welds have been completed for 2830 pipe and tube plates.
