ASME B16.5 Class 1500 Flange
Purchase ANSI 1500 LB RTJ Flange and Class 1500 welding neck flanges at lower price.
ASME B16.5 class 1500 flange is a higher class of flanges in the B16.5 standard. There are flanges ranging from class 150 through class 1500 in this standard. R.C. Metal Corporation is a leading supplier and manufacturer of the ANSI 1500 LB RTJ Flange and other types of flanges. The rtj flanges is a ring type flanges. The other types based on the face are the flat face and raised face flanges. The rtj is a two rings set up that is welding onto pipes for connection. The Class 1500 welding neck flanges have welded necks on them. These flanges range from ¼ inches in nominal bore size to 24 inches. There are different manufacturing types such as the Class 1500 Forged Flanges, screwed flanges and the threaded flanges. Each type of flange is used in different purpose and application.
ASME B16.5 Class 1500 Flange
The 1500# flat flange is a flat face flanges with a lower class of 150. The classes are based on the wall thickness of the flanges and the nominal diameter. The 1500 lb slip on flanges and other flanges also have pressure numbers to denote the maximum pressure capacities. There are PN6 through PN64 pressure numbers. The 1500# blind flange is a special flanges that it closes a connection than expand it. The blind flange is either welded for permanent closure of a line or bolted for maintenance services. The Class 1500 pipe flanges can also come in different material grades.

The stainless steel ones are the most common and the 304 grade is the most used because of the low cost of the material. The 1500# Ring Joint Flanges is used in connections where the pipes have to be excessively welding together and the stress or pressure is high. The Class 1500 slip on flange is used with seamless pipes mostly because it allows the pipes to slip onto them for precise connection procedure. The flanges can be bolted or welded. The CL 1500 rtj flange have to be welded for maximum efficiency. As a leading supplier, we supply all different types such as the Class 1500 socket weld flange and others. Please contact us for a complete price list.
