Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Improper cleaning of pipe ends before connection.Thoroughly clean all pipe ends and fitting surfaces with a lint-free cloth and approved solvent to remove any grease, dirt, or debris that could compromise the seal.
Over-tightening or under-tightening threaded connections.Utilize torque wrenches to achieve the manufacturer-specified torque values for threaded connections, ensuring a secure seal without damaging threads or components.

Common Applications

  • Chemical processing plants
  • Petroleum and gas industries
  • Food and beverage production
