Red Deer, AB - Manufacturing Reciprocating Pumps -> Induction Heat Treating

Barrel tube heat treating

• SupraHard hardened steel barrels
• High frequency induction heating followed by an immediate cold water quench
• Close tolerance induction coils and integral quench heads ensures a consistent uniform hard case
• Special high carbon grade tubing is used to obtain the highest possible hardness
• Uniform case depth of 0.035” on average
• Uniform 60 HRC to a minimum of a 0.010” depth
• Output is around 1000 ft/day (depending on barrel length)
• Cost of equipment and R&D was $250,000
• Patented internal integral coil and quench head
• Developed over 3 years in 1985 (only one in existence)
• The unit was built by Quinn’s except the induction high frequency generator

Advantages

• Hardened case of 0.010”, which is more than adequate for normal barrel wear of 0.005” – 0.008”
• Bulk of wall thickness remains tough and ductile (23 HRC) as per NACE (stress and H2S embrittlement)
• Barrel tube is ready for precision honing and threading
• Cost effective, efficient, and environmentally safe
