1.0 INTRODUCTION

Sabarmati Gas Limited is promoted by BPCL & GSPC for developing City Gas Distribution Network in the

4 Gas /districts of North Gujarat i.e. Gandhinagar, Mehsana, Sabarkantha & Patan.

Sabarmati Gas Limited (SGL) (hereinafter referred as Owner), is a system driven, procedure oriented,

customer centric organization progressively enhancing volume of business, sales turnover, profits and

market share year after year.

SGL predominately serves 4 segments in its whole spectrum of retailing of Natural Gas. These four

segments are Domestic, Industrial and Commercial/Non Commercial customers through PNG and

automobiles through its CNG outlets through its CGD and CNG networks

PNG is a mixture of hydrocarbon gases and vapours consisting of principally methane in gaseous form. The

PNG network consist of receiving natural gas from suppliers at city gate station (CGS), steel mains,

pressure regulating installations (PRI), poly ethylene (PE) mains and supply system to end users.

SGL intends to develop its CGD and CNG network in Gandhinagar, Mehsana, Sabarkantha and Patan in

Gujarat to supply Natural gas to Domestic, Commercial consumers through MDPE network and to new

CNG stations through Steel pipeline network by setting up new facilities.

Natural Gas (NG) is today increasingly gaining popularity over as alternate auto fuel primarily because it is

environment friendly, economical and more efficient as compared to other conventional auto & kitchen

fuels. Emission of harmful oxide and other polluting particulates is minimal in case of CNG.

SGL intends to appoint supplier/s for the supply of PE 100 MDPE pipes of 32mm, 63mm, 90mm & 125mm

pipes.

SGL is now inviting tenders on Competitive Bidding basis for procurement of Medium Density

Polyethylene Pipes for this project.

The present document covers the technical specifications for the enquiry.

2.0 TECHNICAL SPECIFICATIONS

11.0 ANNEXURE K (CLAUSE 11) - SUPPLY, PACKAGING, HANDLING AND TRANSPORTATION OF

POLYETHYLENE PIPES FOR GAS TRANSMISSION

K.1 SUPPLY

ADD

Prior to execution of the order, the manufacturer must submit to the company the seals which it intends to

use for all the types of pipes ordered. The seals shall preferably be made of PE or material which does not

adulterate polyethylene. Metal and PVC seals are not permitted. The seals must be able to withstand storage

terms as guaranteed in K.6 STORING of this Annexure, and also to withstand handling during installation.

They must not be brittle or sharp and the materials, shapes and dimensions thereof most are such that they

cannot fully penetrate inside the pipes. They are of the internal plug type for all pipes supplied in straight

lengths, and or pipes rolled in coils, the seals may be caps.


P.012213

M11097

001


All seals shall be placed on the pipes immediately after completion of manufacturing & testing. Their

removal on site should not require the use of special tools.

PE can be delivered in straight length or coils, transported and stored. Care should be taken to maintain the

coil diameter at or above the specified minimum to prevent deformation. The pipe should be wrapped with

non transparent PE films of 100 mm gauge to protect from ultra violet rays.

K.4 Handling

ADD

PE pipe is relatively light and flexible however, it is susceptible to damage from sharp objects and stones. It

should not be dragged, dropped or subjected to rough handling during loading or unloading, transport,

storage or actual installation.

K.5 Transportation

ADD

When being transported, care should be taken to ensure pipes are not restrained in such a manner as to cause

damage to them. Sharp sections bearing against the pipes should be avoided so as to minimize the chance of

indentation or scoring of the pipe wall.

Pipes with end treatment should be stacked or supported in such a way that the ends are free from loading.

Pipe ends, particularly ends cut for jointing, should be given special attention at all times to ensure they are

free from damage.

K.6 Storage
