There are 90degree DN150 SCH40 ASTM A234 WPB R=3D ELBOW BEND products which are used for the schedule 40, with a medium pressure containment and with DN150 size and with a radius 3 times the outer diameter of the pipe. The naming of the bends give the mechanical and physical properties of the bends for customers to determine which ones they need for specific applications.


We also manufacture the ASTM A234 WPB Sch40 Carbon Steel 90 Degree Elbow Bends and the much larger radius ASTM A234 WPB 90 Degree 5D Elbow as well. Our production includes ASTM A234 WPB Piggable Bend for applications with regular internal cleaning and inspection. The ASTM A234 WPB CS SMLS BW PIPE ELBOW produced by us is of high quality and standards. We also produce the ASTM A234 WPB Carbon Steel J Pipe Bend which is good at drain systems for easy installation. You can contact us for all kinds of WPB pipe bends.
