1、焊接式铜管接头：利用接管与管子焊接。接头体和接管之间用O形密封圈端面密封。结构简单，易制造，密封性好，对管子尺寸精度要求不高。要求焊接质量高，装拆不便。工作压力可达31.5MPa，工作温度-25～80℃，适用于以油为介质的管路系统。
2、卡套式铜管接头：利用卡套变形卡住管子并进行密封，结构先进，性能良好，重量轻，体积小，使用方便，广泛应用于液压系统中。工作压力可达31.5MPa，要求管子尺寸精度高，需用冷拔钢管。卡套精度亦高。适用于油、气及一般腐蚀性介质的管路系统。
3、扩口式铜管接头：利用管子端部扩口进行密封，不需其他密封件。结构简单，适用于薄壁管件联接适用于油、气为介质的压力较低的管路系统。
4、插入焊接式铜管接头：将需要长度的管子插入铜管接头直至管子端面与铜管接头内端接触，将管子与铜管接头焊接成一体，可省去接管，但要求管子尺寸严格适用于油、气为介质的管路系统。
5、锥密封焊接式铜管接头：接管一端为外锥表面加O形密封圈与接头体的内锥表面相配，用螺纹拧紧。工作压力可达16～31.5MPa，工作温度-25～80℃适用于油为介质的管路系统。
6、扣压式胶铜管接头：安装方便，但增加了一道收紧工序。胶管损坏后，接头外套不能重复使用，与钢丝编织胶管配套组成总成。可与带O形圈密封的焊接铜管接头联接使用。适用于油、水、气为介质的管路系统。介质温度：油：-30～80℃;空气，-30～50℃;水、80℃以下。
Before the specification of copper pipe joint, the following copper pipe quick connector, red copper water pipe and copper water pipe manufacturer should first describe the type of copper pipe joint?
1. Welded copper pipe joint: use nozzle to weld with pipe. The O-ring face seal is used between the connector body and the connecting pipe. The structure is simple, easy to manufacture, with good sealing performance, and the requirements for pipe size accuracy are not high. It requires high welding quality and inconvenient assembly and disassembly. The working pressure can reach 31.5MPa and the working temperature is - 25~80 ℃, which is applicable to the pipeline system with oil as the medium.
2. Ferrule type copper pipe joint: it uses ferrule deformation to clamp the pipe and seal it. It has advanced structure, good performance, light weight, small size, convenient use, and is widely used in hydraulic systems. The working pressure can reach 31.5MPa, which requires high precision of pipe size and cold drawn steel pipe. The precision of ferrule is also high. It is applicable to the pipeline system of oil, gas and general corrosive medium.
3. Flared copper pipe joint: the end of the pipe is flared for sealing without other sealing parts. The utility model has simple structure and is suitable for the connection of thin-walled pipe fittings, and is suitable for the pipeline system with low pressure of oil and gas as the medium.
4. Plug-in welded copper pipe joint: insert the required length of pipe into the copper pipe joint until the end face of the pipe contacts with the inner end of the copper pipe joint, and weld the pipe and the copper pipe joint into a whole, which can eliminate the connecting pipe, but the pipe size is strictly applicable to the pipeline system with oil and gas as the medium.
5. Taper seal welded copper pipe joint: one end of the connecting pipe is the outer cone surface plus an O-ring to match the inner cone surface of the joint body, and it is screwed tight. The working pressure can reach 16~31.5MPa, and the working temperature is - 25~80 ℃, which is applicable to the pipeline system with oil as the medium.
6. Compression type rubber copper pipe joint: easy to install, but a tightening process is added. After the rubber hose is damaged, the joint jacket cannot be reused, and it is matched with the steel wire braided rubber hose to form an assembly. It can be connected with welded copper pipe joint with O-ring seal. It is applicable to the pipeline system with oil, water and gas as the medium. Medium temperature: oil: - 30~80 ℃; Air, - 30~50 ℃; Water, below 80 ℃.
