Description

Stainless steel special-shaped tube Technical Field The utility model relates to the technical field of special pipes, in particular to a stainless steel special pipe. Background The deformed seamless steel pipe is a generic term for seamless steel pipes having other cross-sectional shapes than round pipes. The D-shaped stainless steel pipe is a common special pipe and is often used in the fields of construction, automobiles, agriculture and the like. However, the existing D-shaped stainless steel pipes are required to be fixed through bolts when being connected with each other, the installation is troublesome, the tightness is relatively poor, and the leakage phenomenon is easy to occur at the connecting position, so that aiming at the current situation, the development of the stainless steel special pipe which is convenient to connect with each other and has double sealing and better tightness is urgently needed, so that the defects in the current practical application are overcome, and the current requirements are met. Disclosure of utility model The utility model aims to provide a stainless steel special pipe for solving the problems in the background technology. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides a stainless steel abnormal shape pipe, includes abnormal shape pipe, grafting frame, first sealed rubber ring, joint circle and second sealed rubber ring, grafting frame welded fastening is in the left end of abnormal shape pipe, the outside fixed mounting of grafting frame has first sealed rubber ring, the outside size of first sealed rubber ring is greater than the inside size of abnormal shape pipe by one millimeter, joint circle fixed mounting is in the inside right-hand member of abnormal shape pipe, be fixed with the second sealed rubber ring on the joint circle, the outside size of second sealed rubber ring is greater than the inside size of grafting frame by one millimeter. Preferably, the left end of the first sealing rubber ring is provided with a first chamfer. Preferably, the end part of the second sealing rubber ring is provided with a second chamfer. Preferably, the special pipe comprises a bottom plate and a top cover, wherein the bottom plate and the top cover are welded and fixed, and the bottom plate and the top cover form a D shape. Preferably, a plurality of reinforcing rib plates are welded and fixed at the inner top end of the special pipe. Preferably, the bottom plate, the top cover, the plug frame, the reinforcing rib plates and the clamping rings are all made of stainless steel. The stainless steel special-shaped tube has the beneficial effects that when the stainless steel special-shaped tubes are connected with each other, the plug frame at the left side of one special-shaped tube is inserted to the right end of the other special-shaped tube, the plug frame and the first sealing rubber ring are gradually inserted into the special-shaped tube, the first sealing rubber ring is gradually extruded, so that the first sealing rubber ring is tightly attached to the inner wall of the special-shaped tube, the first resealing is realized, the plug frame and the first sealing rubber ring are continuously inserted, the second sealing rubber ring gradually enters the inner ring of the plug frame, and the second sealing rubber ring is gradually compressed, so that the second sealing rubber ring is tightly attached to the inner wall of the plug frame, and the second resealing is realized. In conclusion, the utility model has the advantages of convenient interconnection, double sealing during interconnection and better sealing performance.
