Overview

* Outlet engineering method is widely used in advanced countries and can be applied to the local piping.

Strengths of PLS Outlet

  • It is an all-in-one product, reducing the risk of leakage and rupture and manufacturing cost by reducing the number of joints and welding volume.
  • With the welding improvement angle and the welding reinforced by pad, it is excellent in safety.
  • By minimizing the cutting of pipes, material loss is reduced and pipe quality is maintained.
  • It is possible to manufacture on site and easy to respond to repair and design change.
  • The convenience of installation improves work efficiency and reduces construction period.

Comparison of Construction Methods

  • Reduction of construction period by improving the work efficiency through factory manufacturing and on-site module assembly
  • Reduction of labor cost by reducing skilled workers and on-site manpower due to factory manufacturing and on-site module assembly
  • Improving the work environment when installing on site by minimizing contacts with other processes
  • Reduction of material costs due to the reduction of pipe scraps and reduction of used parts
  • Possible to manufacture on site and easy to respond to repair and design change

Conventional Tee (welding, screw)
  • It has been universally used until now.
  • High construction cost due to a large amount of welding
    Increase of construction period and labor cost due to manual work during screwing
  • A lot of material loss due to pipe cutting
  • Risk of leakage due to the large amount of screwing and welding

Construction Methods

Perforation

Punch in advance at the perforation location and make a hole that meets the specification at the dividing area using a hole saw.

Tack Welding

Conduct tack welding on 4 places so that the product does not move during welding. (It is the welding to keep the outlet in the correct position before main welding.)

Product Welding (Main Welding)

Conduct fillet welding along the pad of the outlet and the pad reinforces the pipe safety and the pressure area.
