Installation Procedure

1. Clean both ends of the pipe and the mating fitting thoroughly to remove any debris or contaminants. 2. Apply appropriate threading compound or PTFE tape to the male threads of the pipe or fitting. 3. Carefully thread the pipe into the fitting, ensuring straight alignment to avoid cross-threading. 4. Tighten the connection using a pipe wrench or appropriate tool, applying firm, steady pressure until a secure seal is achieved.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong type of sealant for the fluid or temperature.Consult the material compatibility chart for the specific fluid and operating temperature to select the correct sealant or tape.
Over-tightening threaded connections, which can lead to thread damage or pipe deformation.Tighten connections until a snug fit is achieved and a visible seal is formed, then apply an additional quarter to half turn, depending on the fitting type and material.

Common Applications

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

⚠️ Engineering Warnings

  • Ensure proper material compatibility with the conveyed fluid to prevent corrosion.
  • Always use appropriate personal protective equipment (PPE) during installation, including safety glasses and gloves.
