what is ISO 3183 oil and natural gas pipeline

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. he main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be […]

comparation of carbon steel pipes and black pipes

what  is black pipe? Black steel pipe is the uncoated steel and is likewise called as black steel. The dark color originates from the iron-oxide formed on its surface during manufacturing. When steel pipe is forged, a black oxide scale types on its surface area to give it the finish which is seen on this type of pipe. Black pipelines are used to bring water and gas from their sources to the end users. It is the pipe that is used by houses and businesses to convey their supply of natural or propane gas. Due to the fact that of […]

ASTM A53/A53M Standards Specification for Pipe, NPS 1/4 INCH – 30 INCH ,Schedules 10 -160, STD, XH and XXH Welded and Seamless

ASTM A53/A53M Standards Specification for Pipe, NPS 1/4 INCH – 30 INCH ,Schedules 10 -160, STD, XH and XXH Welded and Seamless , Black and Hot-Dipped, Zinc-Coated ASTM A53 VS A153 steel ASTM A53 pipe covers Welded and also smooth, Black and also Hot-Dipped Galvanized nominal (average) wall surface pipeline for curling, bending, flanging and also other unique objectives and appropriates for welding. Continuous-Welded pipeline is not intended for flanging. Objective for which pipeline is planned should be specified on order. Of all, we have to differentiate the distinction between ASTM A53 and also ASTM A153. Many galvanizers are familiar […]
