Nonmetal filling medium for producing piping branch junctions and technique for squeezing the piping branch junctions

The invention relates to a non-metal filling medium used for fabricating a three-way pipeline and a process for extruding the three-way pipeline. The filling medium is a non-metal power material whichis uniformly mixed and consists of three powders: talcum powders H2Mg3(sio3)4, industrial salts NaCl and urease (NH4)2CO; the three powders are uniformly mixed respectively according to the mass proportion of 5-25%, 95-50% and 0-25%. The extrusion material range of the three-way pipeline of the invention is multiple high-plastic materials such as copper, iron, low carbon steel and cold extrusionstainless steel and the like; therefore, the high-plastic materials can be extruded and fabricated. copper three-way pipeline, iron three-way pipeline, low carbon steel three-way pipeline and stainless steel three-way pipeline and the like are fabricated. The non-metal filling medium and the process of the invention have obvious technical advantages of meeting the instruction requirement which isissued by European, Japan,
