-INTRODUCTION

Iranian Gas Engineering & Development Company a subsidiary of National Iranian Gas

Company (NIGC). Has intended to perform a !" gas transmission pipeline about #$%

m in 'oute of 'ast*ariNe+a. te ,ro-et /ill be E0euted in % ,ase as 1asi &

Detail Engineering Contrat.

2e purpose of onstruting tis pipeline is to transfer !!!!34! #5#per day 6ean Gas

from 'ast Compressor *tation to Ne+a Compressor station and onsumers loated

along side of te pipeline7 also beause of e0ist #!" old pipeline te ne/ !" pipeline /ill

andle a part of e0isting pipeline duty in about 8! ,erent of 9verall ,ipeline route.

De*('o(#
