1.0 General

This Welding Procedure Specification had been duplicated from PTT welding procedure specification which established and qualified by PTT PLC. And proposed for construction, maintenance, modification and repairing all of PTT gas pipeline and station.

2.0 Scope of Work

This welding procedure specification is proposed for all welding work of Gas Pipeline And Gas Metering and Regulating Station Project if essential variables as describes in API 1104 are not changed then this procedure should applied without the need for requalification.
