PROSEDUR PURGING

1. Persiapan

1. Pastikan lokasi pekerjaan aman dan siap untuk pelaksanaan pekerjaan, dan beri pembatas pada area dengan garis pembatas (safety line).

2. Pastikan semua valve pada clossed dan skillet terpasang dengan benar3. Informasikan kondisi kesiapan dilapangan ke PT. BBG

2. Proses N2 Purging Pertama

Pastikan valve existing pada posisi clossed dan skillet terpasang dengan benar (sesuai prosedur venting PT. BBG).

1. Pasangkan N2 ke valve venting di upstream2. Buka Valve venting, sambil mengukur kadar CH4/O2 di venting dengan gas

detector.3. Apabila kadar CH4/O2 terukur sudah mencapai 2% dan tekanan N2 mencapai 0.5

barg, tutup valve venting di upstream, dan valve venting di downstream.

3. N2 Purging Kedua

1. Pasangkan N2 ke valve venting di upstream2. Buka Valve venting, sambil mengukur kadar O2 di venting dengan gas detector.3. Apabila kadar O2 terukur sudah mencapai 2% dan tekanan N2 mencapai 2 barg,

tutup valve venting di upstream, dan valve venting di downstream.

Fleetweld® 5P+ from Lincoln Electric is first choice for pipe welding, and vertical-up and overhead plate welding.

Ideal for steel that’s less than 100% clean. It’s a first choice for pipe welding, and vertical-up and overhead plate welding. This electrode is a long-time favorite among operators who handle cross-country and in-plant pipe welding.

• All-position, particularly good for vertical and overhead.• Light slag with little slag interference for easy arc control.• Deep penetration with maximum admixture.• Capable of x-ray quality welds, out-of-position.• Manufactured under a quality system certified to ISO 9001 requirements.

Typical Application:

• Tolerates galvanized, plated, dirty, painted or greasy steel which cannot be completely cleaned.• Pipe welding -- cross country and in-plant.• Joints requiring deep penetration such as square edge butt welds.• Repair welding.
