For stainless steel elbow, the pipe orifice of the elbow of the product is provided with a lining. One part of the lining is located in the pipe orifice, which is fixedly connected with the inner wall of the wide mouth. The other part of the lining is located outside the pipe orifice. The lining of the product located outside the pipe orifice is provided with a slit. When the stainless steel elbow is connected with the stainless steel pipe, it is easy to butt install, can eliminate the tension generated by the pipe connection, and has strong deformation resistance. After welding, the connection will not deform after a long time of use, and the installation and decoration effect is good. The stainless steel elbow relates to the field of architectural decoration, and its technical key points are: including the elbow body. The elbow body of the product includes a curved bending section and a straight line section respectively connected at both ends of the bending section, and also includes an arc bending resistance part. Both ends of the bending section of the product are connected by the bending resistance part, and the two parts form a hollow. The bending resistance of the elbow body is enhanced through the setting of the bending resistance part, thus increasing the service life of the elbow body.
