TUBING
• High quality alloy steel tubing
• Consistent straightness and heat treatment
• All tubing available in DCDMA sizes
THREAD
• Tapered, course threads (3 threads per inch) provides easy make
and break
• Load efficiency of 30% provides sufficient strength for average
applications
THRU-WALL HEAT TREATMENT
• Provides 140% material strength
• Heat treated box threads significantly increases thread wear life
CASE HARDENING
• Significant research, development and field testing have resulte din
a hardening process that is unequalled
• Pin thread crest is hardened to nominal 55 HRc to eliminate
damaging ‘adhesion’ wear
• Eliminates the transfer of wear material back and forth which is
what happens between threads of equal hardness, leading to large
scalegalling and joint seizing.
