To ensure a properly sealed and leak-free threaded connection during the welding process, follow these crucial steps:

  1. Thorough Cleaning: Initiate the process by meticulously cleaning the male threads of the threaded welded outlet and the female threads of the existing pipe. Diligently remove any dirt, grease, or debris that might hinder the sealant’s effectiveness.
  2. Appropriate Sealant Selection: Choose a thread sealant or tape specifically designed for the fluid or gas being conveyed. As different sealants are formulated for various applications, ensure compatibility and suitability for your specific requirements.
  3. Precise Application: Apply the thread sealant or tape strictly according to the manufacturer’s instructions. Ensure uniform distribution and complete coverage of all threads, creating an uninterrupted barrier against potential leaks.
  4. Hand Tightening for Alignment: Begin the connection by hand-threading the threaded welded outlet onto the existing pipe. This step allows for proper alignment and engagement of the threads.
  5. Controlled Wrench Tightening: Once hand-tightened, use an appropriate wrench to further tighten the connection. Apply gradual and controlled force to achieve a secure seal, avoiding over-tightening that could damage the threads or cause leaks.
  6. Visual Inspection for Assurance: After tightening, conduct a thorough visual inspection of the threaded connection. Look for any gaps or irregularities, ensuring that the sealant or tape is properly seated and there are no visible signs of leakage.
  7. Pressure Testing for Validation: If feasible, perform a pressure test on the completed connection to verify its integrity. This proactive measure helps identify potential leaks before the welding process begins.

By diligently following these steps and paying meticulous attention to preparation, sealant selection, application, and inspection, you can significantly reduce the risk of leaks and ensure a secure and reliable threaded connection during the welding process.
