The GL pipe is a dual-circuit (two-row) or multi-circuit (four-row) air heat exchanger. The working fluid heat source is steam and high temperature water, and the cold source is low temperature water or salt water. The fin tubes of the GL radiator tube are all made of φ18x2m/m seamless steel pipe or stainless steel pipe wound with 10x0.35m/m steel or stainless steel belts, which are in a spiral shape with a sheet pitch of 3.2m/m. 

　　In order to meet a large number of users' needs, our company organizes assembly line production, so the original GL-type pipe is simplified. The simplified GL-type pipe has the same specifications as the original and can meet the needs of various projects.
