Stainless steel pipe fittings can be divided into arc welded pipes, electric resistance welded pipes (high frequency, low frequency), gas welded pipes, furnace welded pipes, etc. according to the process. According to the purpose, they can be divided into pipeline steel pipes, thermal equipment steel pipes, mechanical industry steel pipes, petroleum and geological drilling Steel pipes, container steel pipes, chemical industry steel pipes, special purpose steel pipes, etc.,
In the process of pipeline planning and construction, especially in flammable, explosive, high-temperature and high-pressure environments, whether it is in the planning and selection of materials, in processing and manufacturing, until the completion of the construction equipment, there will be professional and technical personnel to be strict Check to ensure that the quality of stainless steel pipe fittings in all aspects of material selection, manufacturing, and equipment can meet the standard operating conditions, otherwise incalculable harm will be presented in the future construction and use process.
The internal threads on stainless steel pipe fittings are usually tapped with taps. It is necessary to select a better tap material, appropriately increase the tap rake angle, and reasonably select the tool heat treatment method to take into account the hardness and toughness of the tap.
