carbon oil &gas pipeline



The size of gas pipelines could range from 2 -60 inches in diameter whereas, for oil pipelines it ranges from 4 – 48 inches inner diameter depending on the requirement. Oil pipeline could be made of either steel or plastic however the vastly used one is the steel pipe. Thermal insulated steel pipes are commonly used for oil and gas transportation.

Benefits of steel pipes:
Steel pipelines which lie buried for hundreds of years has extraordinary properties including excellent stress crack resistance to natural gas. They are contaminant and has superior impact resistance, high HDB rating at 20°C, 60°C and 80°C, low permeation to methane and hydrogen. It has got amazing dependable UV performance for outside storage. The insulation material is usually polyurethane foam (PU) which has high thermal efficiency and is mechanically strong.

Best oil & gas pipeline:
Small, medium and large diameter steel pipes are available however, the high strength of steel 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 which assures consistent quality in its application. ERW pipes are equally good in hot or wet applications like river crossing and rough terrains.

The strategic importance of oil and gas transportation and distribution for the energy supply has emphasized the production of line steel pipes and tubes. Corrosion proofing, water based paint is applied on the outside pipe surface to protect against atmospheric corrosion during transportation and storage and a 3-layer protective PE coating can be applied on pipes at the Customer's request.


Line steel pipes are long distance pipelines for combustible liquids and gases. Seamless line pipes used for construction of long distance pipelines for combustible liquids and gases, nuclear station pipelines, heating system pipelines, general-purpose pipelines. Thus, toughness requirements for line steel tubes are more complex than the tensile property requirements.


Line steel pipes are manufactured and smelted in the electric furnace, treated with synthetic slags and cast by continuous casters. The applied steel making process ensures the achievement of chemically pure steel with reference to sulphur and phosphor contents providing high tensile, ductility and corrosion resistance properties of pipes to be operated at low temperatures in various corrosion media.


Thermally insulated steel pipelines 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 oil and gas pipes 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.
