Straight Pipe


Procedure

- cutting material

- Welding seam preparation

- Pre roll bending of plate tip

- Rolling

- Pre heating

- Welding the vertical seam inside

- outside gas gauging(gas explosion) and cleaning root, then welding outside

- rolling to correct ovality

- Respecting tollerance

- assembly and welding neck flanges, welding 100% full penetration, make sure the straightness, perpendicularity

- assemble and welding hoisting eyes and other plates on the pipe

- do blasing and painting.

Assembly

Installation fitting is the root of a separate straight pipes also the corresponding valve member is connected to the ship together, and with a fixed support, and devices connected to the system and finally to form a complete pipe system.
