What should be paid attention to when designing stainless steel pipe fittings
The connection between the wall of the round corner of the stainless steel pipe fittings should have the casting round corner. The structure that does not have filar horn, metal accumulates in right Angle place, hot nodular circle is bigger than other place, easy generation shrinks hole and shrink loose, and inside corner office stress concentration is serious, easy generation flaw. The above defects can be prevented by designing the valve Angle.
Some metals in the right Angle place crystal is suitable to cross, produces the crystal between the cohesive force to be weak, the pipe fitting in the corner corner mechanical performance has declined, increased the crack generation. Therefore, it is necessary to design the corner into a round corner, casting into a round corner is more conducive to modeling, avoid damage to the sharp Angle of the casting and the formation of sand holes, reduce the sand casting, so as to make the casting beautiful.
Shandong mingxing stainless steel casting co., LTD. : avoid the connection between the intersection and the sharp Angle. In order to effectively prevent the shrinkage cavity and porosity of the stainless steel pipe fittings, the connection of the castings on the pipe fittings should be avoided from crossing. Medium and small pipe fittings can use staggered joint, large pipe fittings choose ring joint.
