The blast joint is positioned opposite the perforations in the casing, it is used in the tubing string of a flowing well to prevent tubing damage caused by the jetting action of the flowing well. The blast joint has the same ID of standard tubing and OD of coupling. This thick wall pipe design provide maximum protection of the tubing by isolation of the erosive section from the standard tubing.

　　Blast Joints are made from high quality steel treated to between 28 & 36 RC hardness to insure maximum abrasion resistance and strength. Standard Blast Joints have an API EUE thread connection. Custom thread can be ordered. ETANG can provide blast joints with lengths of 10ft or 20ft, and can also be customized according to customers' requirements.
