Bids Are Invited For Rig Room-614 Shop-Conv-Process, Rig Room-614 Shop-Others - Scope Of Work – Rig Room 1. Scope Of Work For “Conventional Machine And Process Activities”: I. Flow Test: Flow Range Of Components, Approx. 0.4 – 4.05 Litre / Min At Pressure 2.5 Kg / Cm2 , Dimensional Range Of Holes Approx. Dia 0.4 – 2.1 Mm. If Flow Rate Of The Component Is Measured ( Using Technological Fixture ) Lower Than The Technological Limit Then Drilling / Reaming / Lapping Of Hole Has To Be Carried Out Till Achieving The Required Flow. Technological Rig And Fixture Is Used During Flow Test. Working Fluid In This Test Is Oil / Atf. Ii. Leak Test / Hydraulic Test: Pressure Range Of Leak Test Components ( Pipelines ) Varies Approx. 15 – 330 Kg / Cm2 . Diameter Of Pipe Varies Approx. 6 – 24 Mm .Technological Rig And Fixture Is Used During Leak Test. Working Fluid Of The Test Is Atf. Iii. Direction Test: Jet Spray Of Components Has To Be In A Particular Direction. In Direction Test, It Is Checked Whether The Jet Spray Is Passing Through The Required Slot Or Not. If The Spray Is Not Passing Though That Slot Then Adjustment Of The Component Is Required Until Achieving The Proper Direction Of Spray Of The Component. Technological Rig And Fixture Is Used To Check The Direction Of Fuel / Oil. Working Fluid In This Test Is Oil / Atf. Iv. Priming / Preservation: Flushing With Oil Under Pressure 2 Kg / Cm2 For 2 To 3 Minutes. Temperature Of Oil 50 – 60 Degree Celsius. Technological Rig Is Used In This Operation. V. Stripping: Dismantling Of Roh Assembly Components By Using Technological Fixture, Tools, Spanner Etc. Vi. Washing / Flushing: Cleaning Of Components By Using Naptha / Petrol / Atf To Remove Carbon Deposit Or Dust Particles. Vii. Deburring: Smooth Finishing Of Rough Edges Of Components Is Done By Using Deburring Tool Or Hand Tool. Burrs Are Not Allowed As Per Technology. Viii. Dressing: Removing Dents, Nicks, Pin Holes From The Surface Of The Components By Doing Bench Work Or By Using Polishing Wheel. Ix. Polishing / Blue Check: Leak Proof In Mating Components Is Ensured By 100 Percentages Blue Checks On Its Taper Surfaces ( Angle 74 Degree ) . Tapered / Conical Mandrel Is Used During Polishing Of Taper Surface Of The Component Till, Achieving The Required Blue On Its Surface. Blue Check Has To Be Carried Out By Technological Blue Check Gauges. X. Assembly: Certain Detail Components Are Assembled To Make A Sub Assembly Component. Technological Fixtures And Tools Are Used During Assembly Operation. Xi. Miscellaneous: Any Operation Pertaining To Manufacturing Or Roh Activities Carried Out In Rig Room Like Lapping / Locking Hole Cleaning, Etc Not Described In Above Are To Be Considered Under “Conventional Machine And Process Activities” Category. 2. Scope Of Work For “Other Activities”: Operations Like Washing, Cleaning, Packing, Marking Etc. Involved In Manufacturing Or Roh Activities Carried Out In Rig Room. Total Quantity : 70200
