Description: Blast Joint is thick walled tubing with typical length 10' or 20' that installed in production string. It protects tubing string from the abrasive action of flowing gas or oil when positioned opposite the perforations. Blast Joints may also be used directly below the well head to protect from the abrasion of doing a hydraulic fracturing operation down the annulus. Usage: Blast Joints are used to protect the tubing string from the abrasive action of flowing gas or oil when positioned opposite the perforations. It may also be used directly below the well head to protect from the abrasion of doing a hydraulic fracturing operation down the annulus. A Blast Joint is made from high quality alloy steel to ensure maximum abrasion resistance and strength. Full tubing I.D. is maintained through the Blast Joint with the O.D. the same as tubing couplings. As standard it is available in API tubing connections. Most tubing connections can be supplied, however, I.D./O.D. dimensions may vary depending on the tubing connection and tubing weight. Feature： Full Bore tubing ID Available in all standard or Premium API threads Available in a wide variety of material choices Available in 2ft increments to 10ft length.
