Background technique
Stainless steel elbow is the heavy connection in power plant, chemical industry, petroleum, water supply and pipeline transportation, is used for connecting pipe The pipeline of bending is needed in laying, existing stainless steel elbow is using two kinds of production methods mostly: one is straight using two Pipe connects a flanged (FLGD) elbow and is assembled by bolt, another kind be welded using straight tube and elbow using butt weld and At, it is very inconvenient when assembling and disassembling using first way production bend pipe, the labor intensity of staff is considerably increased, The bend pipe made of the second way is corrosion-resistant, keep the temperature and tensile property is poor, and service life is short, is not suitable in adverse circumstances It uses, therefore, it is necessary to design a kind of integrally formed stainless steel elbow.
Utility model content
To solve above-mentioned problems of the prior art, it is curved that the utility model provides a kind of integrally formed stainless steel Pipe is welded bending tube body both ends and flanged plate by the way that stainless steel tube is processed into bending tube body, then using fish scale weld seam, substitution Traditional elbow and straight tube connecting method, dismounting is more convenient, and corrosion-resistant, heat preservation, tensile property are strong, long service life, It can be suitably used for various adverse circumstances, be widely used.
To achieve the above object, the technical solution of the utility model is: a kind of integrally formed stainless steel elbow, it Including flanged plate, bending tube body, clamp device and straight line tube body, the stainless steel elbow that the bending tube body is integrally formed, Both ends are fixedly connected with flanged plate, and the flanged plate edge is uniformly provided with no less than four groups of through-hole, and passing through in the through-hole has Clamp device simultaneously removably connects straight line tube body by the clamp device.
Further, the bending tube body and flanged plate junction are provided with fish scale weld seam, the bending tube body and flange Plate is seamlessly connected by the fish scale smooth welding joint.
Further, the clamp device includes the screw bolt and nut being mutually threadedly coupled, and spiral shell is located in the middle part of the bolt Sealing ring is socketed at female top, the sealing ring is placed between the flanged plate of two pieces of corresponding installations.
Further, the flanged plate is one of round, rectangular or regular polygon.
Further, the bending tube body extexine is coated with one layer of titanium alloy layer.
Further, the bolt is made of carbon steel, and the nut is made of stainless steel.
The beneficial effects of the utility model are:
1. by the way that stainless steel tube is processed into bending tube body, then bending tube body both ends and flanged plate are welded by fish scale weld seam It connects, instead of traditional elbow and straight tube connecting method, dismounting is more convenient, and corrosion-resistant, heat preservation, tensile property are strong, use Service life is long, can be suitably used for various adverse circumstances, is widely used.
2. using fish scale weld seam more traditional downhand weld or fillet weld, not only good appearance, flatness are high, but also leakproofness Well.
3. bending tube body extexine is coated with one layer of titanium alloy layer, is conducive to the corrosion resistance for improving bending tube body, improves Its service life and the scope of application.
4. screw bolt and nut is made using different materials, locking can be in for a long time to avoid screw bolt and nut The case where being corroded when state, leading to be difficult to dismantle even stripped thread.
