All parts pass rigorous testing per ISO 9001:2015, directly resolving pain points of premature wear, incompatible replacements, and costly equipment failures.
XQ140/12YA Power Tongs Parts
XQ140/12YA power tongs (rated torque 12kN.m) are core equipment for medium-diameter pipe make-up/break-out in onshore drilling and shallow offshore operations. Key components like main shafts and copper washers endure cyclic torque, high pressure, and drilling fluid corrosion—failure can halt drilling for hours. Our parts feature CNC-machined precision and corrosion-resistant materials, ensuring 35% longer service life than generic alternatives and reliable performance in high-vibration scenarios.
Field Fault Maintenance Case
An oilfield operator in Southeast Asia faced frequent oil leakage and torque loss with XQ140/12YA tongs, causing 3+ hours of daily downtime. Inspection revealed worn copper washers (φ22*φ10*3 12AB-275) and a damaged main shaft (XQY12A) due to inadequate lubrication and fluid corrosion. Replacing with our brass washers and 40CrNiMoA main shaft (compliant with API 7K Clause 5.2) and implementing a regular lubrication protocol eliminated issues, reducing downtime to under 20 minutes weekly and cutting maintenance costs by 48%.
