The stainless steel bridge extension elbow is used for offshore engineering, including the horizontal part, vertical part and lifting part. The horizontal part, vertical part and lifting part of the product all include the wall beams on both sides and the crosspiece fixed between the wall beams of the product. The horizontal part, lifting part and vertical part of the product are connected into a whole through their respective wall beams on both sides. One end of the wall beams on both sides of the product's lifting part is connected to one end of the wall beams on both sides of the product's horizontal part, The other end is connected to the lower end of the wall beams on both sides of the vertical part of the product. The end of the product's lifting part connected with the vertical part of the product is higher than the end of the product's lifting part connected with the horizontal part of the product, and the end of the product's lifting part connected with the vertical part of the product is far away from the horizontal part of the product. This product is simple in structure, high in strength, light in weight, with a service life of up to 40 years and a relatively low manufacturing cost.
