Detailed Description
As shown in figures 1 to 7, a high-precision sealing type stainless steel seamless steel pipe adopts brand-new structural design, and holistic structural strength is better, and the tip position is more convenient when carrying out the erection joint, and the assembly sealing stability that can ensure inside and outside both sides is better, and hookup location's combination precision is higher, and the firm in connection nature is better, and the installation and operation in the later stage use is more convenient, and the safety in utilization is better. It includes that the center pin is cylindrical stainless steel pipe major structure 1 of upper and lower direction, the upper end central point of stainless steel pipe major structure 1 puts and is equipped with cylindrical center built-up connection hole 2, the lower extreme of center built-up connection hole 2 will stainless steel pipe major structure 1's lower terminal surface runs through, can carry out current built-up connection to the inside and outside both sides of stainless steel seamless steel pipe when assembling, and the installation compactness of guarantee is better, and assembly operation is more convenient. Be equipped with integrated into one piece's conical accurate combination of reinforcement on the lower terminal surface of center built-up connection hole 2 and stabilize spliced pole 3, the up end central point that consolidates accurate combination and stabilize spliced pole 3 puts the conical internal combination stable connection that is equipped with integrated into one piece and ends a post 4, makes the assembly compactness of inside better, and the combination fastness during the assembly is higher. The stainless steel tube main structure 1 is characterized in that a conical external mounting and matching combination groove 5 is formed in the center of the lower end face of the stainless steel tube main structure 1, and a conical external combination accurate positioning and matching groove 6 is formed in the upper end of the external mounting and matching combination groove 5, so that the combination tightness of the outer side position is better, and the overall connection firmness is more reliable. The tapering of external mounting cooperation combination groove 5 with it is the same to consolidate the tapering of accurate combination stable connection post 3, the tapering of accurate location cooperation groove 6 of external mounting with the tapering of internal combination stable connection end post 4 is the same, makes the structural strength of erection joint position higher, and the durability when using is stronger.
