Threaded joints are threaded pipe connection components, widely used in industrial and daily life fields. Their main functions are to simplify the pipe connection process and reduce maintenance costs . The following is its core information:
1. Youdaoplaceholder0 type and structure
Common types : including threaded elbows, tees, unions, pipe caps, reducers and more than ten other types .
Sealing design : It is composed of a connecting pipe nut, a conical cavity and a sealing ring with a cutting edge. Some models achieve anti-counterfeiting indentation and quality traceability through a 45°-90° bevel design.
Industrial grade : mostly uses metal materials such as carbon steel, stainless steel, and alloy steel, while domestic grade uses plastics such as PVC and PPR .
2. Youdaoplaceholder0 technical parameters
Specification range : compatible with 3/8 "-4" BSP internal and external threads, working pressure up to PN10 (approximately 1MPa) .
Connection method : Supports BSP standard, some models use NPT external thread (45° conical structure) to achieve self-sealing, suitable for low-pressure systems with a pressure lower than 1000psi .
Strength performance : The thread strength is enhanced through cold working hardening process, and the tensile performance exceeds the standard of the base material, meeting the requirements of grade I joints in JGJ107-2003 .
3. Application features of
Industrial advantages : Prefabricated production, construction without electricity or fire, suitable for operation in narrow Spaces, capable of connecting HRB335/400 grade steel bars .
Life application : mostly used in low-pressure scenarios such as plumbing and gas, it relies on sealant or O-rings for auxiliary sealing.
4. Youdaoplaceholder0 Standards and materials
Industrial standard : in accordance with ASME B16.11, MSS SP 83, etc., the sealing ring material is natural rubber or silicone rubber of 65-85RHD .
Drinking water grade : The joints in contact with drinking water shall be made of 304/316 stainless steel, and the sealing rings shall comply with HG/T3097 standard.
