Thermally insulated steel pipeline are extremely important for oil
and gas industry. Steel pipelines, which lie buried for hundreds of
years, has extraordinary properties including excellent stress
crack resistance to natural gas and its contaminants, low
permeation to methane and hydrogen, high HDB rating at 20°C, 60°C
and 80°C, superior impact resistance, squeeze off, and dependable
UV performance for outside storage. The insulation material is
usually polyurethane foam (PU), which has high thermal efficiency
and is mechanically strong. Small, medium and large diameter pipes are available and the high
strength of steel also makes bending and forming more difficult.
Generally, Electric Resistance Welded (E.R.W.) steel Pipe are used
for oil and gas processing and transmission lines registered and
assures consistent quality in its application. These are equally
good in hot or wet applications such as river crossings and rough
terrain. The use of steel provides standard for pipe suitable for
use in conveying gas, water and oil in both the oil and natural gas
industries. Click here to send Query
