5 INTRODUCTION P D INTRODUCTION Gas Authority of India Limited (GAIL) is planning to lay a kms (approx.) Natural Gas Pipeline, with Dispatch Station (DT) at Jwalapur, in the Haridwar District of Uttarakhand State and Receipt Station (RT) in the Dehradun District of Uttarakhand State. This proposed pipeline is hereinafter referred to as Haridwar- Rishikesh-Dehradun Pipeline (HRDPL). The Pipeline Size has been finalized as 8 NB, with a Flow capacity of 1.2 MMSCMD. In addition to DT and RT, the proposed Natural Gas Pipeline shall have Six (6) nos. of Sectionalizing Valve (SV) Stations between the dispatch terminal and receipt terminal and one (1) no. Tap-Off Station for Rishikesh Spur Line. The proposed pipeline is traversing within the vicinity of either existing GAIL s pipeline or proposed ROU of NH-58, NH-72 and other PWD roads of Haridwar and Dehradun and will cross though areas falling under Location Class 1, 2, 3 and 4. However, Location Class 1 & 2 pipe thickness have not been used in the entire pipeline route, only Location Class 3 & 4 pipe thickness have been used in the entire pipeline route. The proposed natural gas pipeline route runs cross-country, between dispatch station and receiving station. The route of the pipeline crosses through Rajaji National Park Wildlife Sanctuary, Reserve Forest, Major River Crossings, Canal/Channel Crossing, Fault Line Crossing, Major District Roads Crossing including National Highways and Railway Lines etc. TE-India is now inviting tenders on Limited Domestic Competitive Bidding basis for procurement of Valves for this project. The present document covers the technical specifications for this procurement enquiry. It forms an integral part and is to be read in conjunction with Volume I of II: Commercial. 2.0 TECHNICAL SPECIFICATIONS The technical specifications for this present tender enquiry are as listed in Material Requisition (No. P D ). 3.0 DEFINITIONS Owner/Purchaser Engineer/Owner s Representative Manufacturer Third Party Inspection Agency (TPIA) Control Authority Shall mean GAIL (India) Ltd; Designate the individual or legal entity to which the Owner has entrusted various tasks in relations with the carrying-out of his project. This also includes PMC (Project Management Consultant) of the Project; Means the Manufacturer of the Valves as well as its sub-contractor(s) including the supplier(s) of Pig Signallers...etc. Means the Inspection Agency to be appointed by Manufacturer Owner / Engineer or their Authorised Inspection Agency Σ Σ Σ Rev. 0 Haridwar Rishikesh Dehradun Pipeline Project Page 1 of 1 Page 3 of 145

The nature of the products shall be specified in the offer and shall guarantee a corrosion protection for a storage period in a shop for at least one year. Painting in accordance with Purchaser/Engineer's specifications. Painting and coating procedures shall be submitted for approval before manufacturing to the authorized Control authority and to the purchaser / engineer.

This table is not intended to represent the composition of any heat of steel, but merely to record the maximum permissible amounts of one element. The combination of elements of any heat must conform to the carbon equivalent, subsection For each heat the Manufacturer shall analyse the following elements : C, Mn, Si, P, S, Nb, V, Cr, Mo, Ni and Cu. The intentional addition of elements other than those specified is not permitted unless agreed upon by the Purchaser. In any case, for unintentional additions, the following limitations shall be respected : Cr 0.15 % Mo 0.05 % Cu 0.20 % Rev. 7 14/09/09 Page 25 of 31 Page 109 of 145

If the Manufacturer cannot give any guaranty of N content, he shall analyse this element. The total content for Nb + V will be limited to %. In grades X42 through X60 for each reduction of 0.01 % below the maximum carbon content, an increase of 0.05 % manganese above the specified maximum is permissible, up to a maximum of 1.70 %.

116 GENERAL TECHNICAL SPECIFICATION GTS/402 ANNEX 1 LOFC (LIST OF OPERATIONS OF FABRICATIONS AND CONTROLS) Each LOFC must contain the following information as a minimum (all clearly marked and separated) : k) Company name and references relating to the order. l) All technical and other information required in order to define the items covered. The area of application will be limited to that item or those considered as in fabrication and control. m) A numerical sequence of operations with description will be built-up in a logical way of work progress. The first operation will be the control of the incoming material(s) and documents. The last operation will be the control of the CMTR. The following operations have to be included (not limited to) : Each fabrication step. Each step which calls for own quality control (eventually QA). Each applicable examination as part of this specification. Document controls - stamping and final documentation. n) Each operation will be followed by the applicable specification or procedure number (with the latest revision). o) Columns to be provided for possible interventions of : the Manufacturer's fabrication control, the Manufacturer's quality control (eventually QA), Control Authority, the Purchaser/Engineer, and place of intervention if not by the Manufacturer. The interventions will be indicated per operation with H or W and/or R. H = hold point No further steps may be undertaken before the intervention of the appointed responsible takes place. Rev. 7 14/09/09 Page 30 of 31 Page 114 of 145

117 GENERAL TECHNICAL SPECIFICATION GTS/402 W = witness point The appointed responsible has to be notified of the operation in advance, but production will continue whether the intervention took place or not. R = point for which a control report or a recording has to be made. The Manufacturer will fill in his own H, W and R points. The Control Authority and the Purchaser/Engineer will do the same in their designated columns, but this will not implicate a relaxation or wearing of the requirements of the Manufacturer's controls. Each intervention has to be signed and dated by the person acting as controller. Only the original documents will be presented for this purpose. p) One column to be provided for report or record numbers (points marked R) and one for the review of these documents by the Control Authority. q) Two extra columns may give reference to a non-conformity report if any and to the resolution given to it. Completion of the LOFC does not automatically give rise to a release of the material or it must be stipulated otherwise in the contract. Rev. 7 14/09/09 Page 31 of 31 Page 115 of 145
