Installation Procedure

1. Ensure pipe ends are clean, free from burrs and foreign material. Verify compatibility with connecting fittings. 2. Apply appropriate threading compound or sealant to male threads before assembly. 3. Hand-tighten connections, then use a pipe wrench for final tightening, applying torque according to ASME B31.3 guidelines to prevent over-tightening and potential damage.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect pipe sealant for the fluid medium or pressure rating.Always consult fluid compatibility charts and select a sealant rated for the specific service conditions and pressure of the application.
Over-tightening threaded connections, leading to stress fractures or leaks.Follow recommended torque specifications for the pipe size and material. Use two wrenches to support the fitting and prevent torque on the pipe itself.

Common Applications

  • High-pressure hydraulic systems
  • Steam and process piping
  • Structural supports in industrial environments

⚠️ Engineering Warnings

  • Not intended for use with highly corrosive media without appropriate coatings or material selection.
  • Ensure proper support spacing to prevent sagging and excessive stress on the pipe and connections.
