General Information: During welding, heating and cutting operations with
oxygen acetylene flame, the gases are transferred through different
storages and cylinders from rubber hose. Therefore the hose should
be:
- Strong
- Durable
- Non-porous
Hence,
PRIMA hoses are the best as these are made from laboratory tested
materials to ensure the right kind ode ruggedness for longer life.
Construction: A good quality hose should have the following features,
- Evenly
braided synthetic rubberized yarn
- Seamless
and uniform thickness
- Smooth
in-bore concentric
- Free
from porosity or air blisters
- For
transferring oxygen, blue hose is used (as per IS 447:1988), and for
acetylene, red hose is used but both are of same grade and
construction
Salient Features: Besides being rugged in design and safety, PRIMA hose
deliver stable pressure in spite of changes in rate of flow,
temperature and other conditions. It strictly complies to
IS
447:1988 and carefully tested for bursting pressure, tensile strength,
elongation, adhesive strength test etc.
