Elbow: Elbow is a common standard pipe fitting in pipelines and
equipment, divided by bending radius, R=1DN and R=1.5DN two kinds,
in order to distinguish 180°, 135°, 90°, 60°, 45°, 30°, etc., its
specifications in DN18-DN200 seamless, DN > 200 for the
longitudinal weld elbow.
Standard:ASTM B16.9,SH3408,SH3409,HG/T21635,HG/T21631,SY/T05010
Grade:Grade1 Grade2 Grade7 Grade9 Grade12
Thickness:1-18mm(Sch5s to Sch80s)
Technology:Production methods can be divided into pushing,
pressing, forging, casting and so on
Dimension:DN15-1200(NPS:1/2-36 inches)
Craft:Seamless extruded or butt-welded elbows, polishing, lathing,
pickling, rolling
Feature:Excellent properties in the medium of acid, alkali and
salt, especially Cl- corrosion resistance. Corrosion resistance to
sewage, scale will not be deposited on the inner surface of pipe
fittings,Low density, high strength, light equipment.
Application: Used in petroleum, chemical industry, electric power,
metallurgy, chemical fiber, food, pharmaceutical, chlor-alkali,
vacuum salt making, fine chemical industry, biological engineering,
seawater desalination, ocean engineering and other industries.
