Threaded pipe fittings is a kind of pipe fittings with threads, which are divided into various types and specifications. This encyclopedia from the threaded pipe fittings, threaded pipe fittings specifications, thread key standards, threaded pipe fittings material, from a number of angles to understand this life is often used in pipe fittings.
What is a threaded pipe?
Threaded pipe fittings is a threaded pipe, can be made of different materials, suitable for a variety of pipe connections, daily application often in the water gas pipe, small diameter water pipe, compressed air pipe and low-pressure steam pipe, etc., with the pipe end of the thread connected to the pipeline, the thread can be coated with appropriate adhesive, such as thick white paint, a lead oxide glycerin glue, etc., to ensure seal.
Type of threaded Fittings
The type of threaded fittings can be subdivided into more than 10 types, covering a wide range of forms such as straight connections used to bend connections, includes a flat head outer wire (short section), which is commonly used in pipe connection; thread four-pass, for four pipes connected to each other; thread tee, for three pipe connections, in addition to the single threaded short section: Two-headed threaded short section, hexagonal head tube plug, square head pipe plug, threaded pipe cap, threaded elbow, hexagon head inside and outside threaded joint (refill), six angle double wire head, single head threaded pipe hoop, Reducer six angle double wire head, threaded movable joint, double head threaded pipe cap, socket movable joint, round head tube plug.
Standard for threaded fittings
GB is the international standard, ASME and MSS are the United States standards, BS is the British Standard:
GB/T 14383: This standard marks the size, material, fabrication, inspection, testing and marking of forged socket welding and threaded fittings, as well as the contents of supplies. Usually used in the industrial piping system with nominal size less than DN100 metal materials forged socket welding and threaded fittings manufacturing.
ASME B16.11: This standard makes a request for pressure-temperature ratings, dimensions, tolerances, standards and materials for socket welding and threaded fittings, and the manufacturer and purchaser can coordinate the fitting of forged rolling materials for special sizes and shapes. The criteria for selecting fittings and materials suitable for use in specific fluids do not fall within this standard range.
MSS SP 83: This standard is used for forged carbon steel and stainless steel pipe joints, socket-welded and threaded end housings and other critical dimensions, surface trimming, tolerances, testing, marking, material and minimum performance requirements.
Threaded pipe Material
There are also many kinds of materials used in the production of threaded fittings, according to different occasions with different material threaded pipe fittings, including cast steel pipe parts, cast iron pipe fittings, stainless steel pipe fittings, plastic pipe parts, PVC pipe fittings, Rubber pipe fittings, graphite pipe fittings, forged steel pipe parts, PPR pipe fittings, Alloy pipe fittings, PE pipe fittings, ABS pipe fittings.
