blast joint

Features & Benefits
Blast Joints are heavy wall tubes which are run as an integral part of the tubing string. The purpose 
of a Blast Joint is to minimize the effect of external erosion action. 
Blast Joints can be located opposite to perforations in dual completions or directly 
below the tubing hanger in sand frac situations.
The Blast Joint is a heavy-walled tubing made from high quality steel with hardness from 28 to 36 HRC to 
minimize the effect of external erosion from the flowing fluids and protect the tubing string. 
The blast joint can be placed opposite to the perforations or below the tubing hanger in sand frac operation. 
Full bored tubing ID is maintained through the blast joint with the OD same as the couplings.
Size Range -OD: 2-3/8” to 7”
Length -6', 8', 10', 20',Customized length

Material Grades -L80, P110, 13Cr, etc.
we can also produce the blast joint for H2S services, the heat-treated material with hardness between 
18 and 22HRC according to NACE MR-0175
