挤压型管接头是将套管接头与导管用挤压而加以连接的管接头。与扩口式,卡套式和焊接球头式相比,此种接头不需焊接,具有许多优点。因为具有连接强度高,密封可靠,装配方便等优点,因而得到新的发展。通过研制实例,就挤压工艺和设备,连接性能和密封性能及其试验结果作了综合性论述。 Extruded pipe fittings are fittings that connect a pipe joint to a pipe by extrusion. Compared with flared, ferrule and ball-type joints, this type of joint does not require welding and offers many advantages. Because of its high connection strength, reliable sealing, easy assembly and other advantages, which have been new developments. Through the development of examples, the extrusion process and equipment, connection performance and sealing performance and test results made a comprehensive discussion.
