specifications and data given in Table-1, Table-2, Table-3 & Table-4 to SDSC SHAR

Sriharikota.

2.0 General description:

2.1 Hoses listed in Table-1 consists of Super Insulated hoses (Multilayer insulation +

vacuum jacketing). The hoses in this Table are classified into two types, namely

Part-A and Part-C. The detailed technical specifications of the same are given in

the subsequent articles. Size, type of hose, fluid media, pressure rating,

temperature, heat-in-leak, length, end connections, quantity are defined in the

Table-1 and Table2. List of accessories required are provided in Table-4.

2.2 Both ends of Part-A hose & one end of Part-C hose are required to be provided

with male bayonets to facilitate assembly with respective female bayonets

available in fixed pipes at SDSC SHAR. Accordingly, the supplier shall supply Part-A

hoses with both end male Bayonet couplings (Johnston coupling or equivalent).

Similarly for Part-C hoses, one end shall be with a male bayonet coupling (Johnston

coupling or equivalent) and other end to be terminated with defined pipe size as

given in Table-2 for further butt welding of matching adapters by purchaser.

Female Bayonet couplings are not included in the present scope of supply.

Outline sizes for male bayonet couplings are provided in attached drawings for

individual hoses. In case, if the supplier is unable to source Johnston coupling or

equivalent, he shall realize the same by generating the fabrication drawings

based on the existing hardware available at SDSC SHAR for which mating parts

will be provided. Safe transportation of available couplings from SDSC SHAR to

suppliers premise will be the responsibility of the party.
