Pipes - continued

SAW pipes - are pirmarily used in transportation
They are of two types

1. Longitudnal SAW (LSAW) - manufactured from steel plates - dia 16'' OD to 56'' OD
   
2. Helical SAW (HSAW) - manufactured from hot rolled coil - dia 20''OD to 108''OD
   

Price of LSAW > Price of HSAW as Steel plates > Hot rolle coil
The difference between the prices of steel plates and hot rolled coils can be in the range of $250-300
HSAW have double the length as  compared to LSAW of 12m

The pipes are used fro structural and piling applications.

Manufacturing process
LSAW: Both UOE and JCO process (J-ing, C-ing, O-ing)

Ductile Iron pipes
- used in water and sewage transportation
- dia of pipes varies from 80mm to 1000mm with length of 5.5m to 6m

Indian pipe sector is teh third largest after Japan and Europe
The oil and gas penetration level in india is 32% as compared to 59% in te USA and 79% globally
Demand triggers
- Higher exports markets due to promitity to middle east
- Lower cost of production by Indian pipe producers

There are differnet types of coatings that can be applied on a pipe
-Polyethylene
Fusion bond epoxy
Coal tar enamel
Concrete weight coating
Internal coating
