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¡ãC, 60¡ãC and 80¡ãC, 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.
