OIL GAS AND LINE PIPES
ASTM, ASME and API
Pipelines are the most economical way to transport oil and natural gas to another region in large quantities. When compared to railways, it is less cost per shipment and higher capacity transport. Pipelines can be built under the sea, both methods require a great deal of attention from the economic and technical side, most of the oil is transported by tanker ships in the seas.
Oil pipelines are made of steel or plastic pipes with an internal diameter of 30-120 cm (12-47 inches). Wherever possible, the pipeline is built on the ground. Pipelines are laid to below 1 meter (3 feet) above ground in urbanized areas, vulnerable environments, or potentially hazardous areas. Pipelines are built with pipelines to provide petroleum movement, usually about 1-6 m / s. For multi-use pipelines, transport is carried out by sending two or more different products in the same order. Generally, no physical separator is used between products in such pipelines. Some mixed products arise due to the fact that the products are shipped together. This mixed product is removed from the pipeline and stored at a different location to avoid mixing with other products.
BOILER PIPES
EN and ASTM-ASME
Boiler tubes are used in boilers, ovens, pots, lanes and tanks under temperatures of 650 ° C and under high pressure. It is used in many places, including oil plants, natural gas conversion plants, panel pipes surrounding the crucibles of iron and steel plants.
MECHANICAL AND CONSTRUCTION PIPES
EN, GOST and ASTM
Steel Pulling Mechanical and Construction pipes are primarily used in areas where pressure resistance is required, and are mainly used for building superstructure construction together with machinery parts or equipment. It is used in places where long life and trust are required both with warmth and high pressure resistance compared to stitched steel pipes.
Especially the most common standard used as stand-up conveying columns in space fence is EN 10210 and quality is S355J2H.
