Carbide Blast Joints, Inc. utilizes a 10,000 sq.
ft., fully equipped facility located north of Houston, in Spring
Established in 1974, C-BJ sought an answer to eliminating failure
in the long string of tubing, due to the blasting effect of gas
and/or oil-produced sand/fines in the upper zone of a dual completion
Carbide is the difference. The patented feature
of our blast joint is a unique continuous sheath of sintered tungsten
carbide on the O.D. of the production tubing string, across from
the upper zone perforations. After considerable developmental testing,
it was found that the most effective method of placing the virtually
indestructible sintered tungsten carbide around the area affected
by blasting was the use of a series of one-inch long, pre-formed
rings. These rings fit over the O.D. of the production tubing.
Flexibility. CBJ's carbide protection can be utilized
in a tubing string featuring flush joint connections, (Slimline
Carbide Blast Joint) non-upset, threaded and coupled connections
(Coonie Connection Blast Joint), as well as Hydraulic Fracing, Steam
and Fire-flooding operations. Essentially, CBJ carbide protection
can be used anywhere API tubing is "run."
