Description

Technical Field

[0001] This utility model relates to the field of seamless steel pipe technology, specifically to a nickel alloy seamless steel pipe that has undergone rust prevention treatment. Background Technology

[0002] Seamless steel pipe is a type of steel pipe without welded joints. It is usually produced by solid pressure processing or rotary processing. This type of steel pipe has no obvious weld seams, so it has high strength and pressure resistance. It is suitable for various high-pressure, high-temperature or critical engineering and applications. Seamless steel pipe is commonly used in petroleum, chemical, natural gas, heating, water supply and other fields. It is favored for its excellent sealing and corrosion resistance.

[0003] Existing seamless steel pipes have an exposed outer surface that is in direct contact with air or soil, making them highly susceptible to corrosion and affecting their service life. To address this, we propose a rust-proof nickel alloy seamless steel pipe. Utility Model Content

[0004] The purpose of this utility model is to provide a rust-proof nickel alloy seamless steel pipe that has the effect of isolating and protecting the outer diameter of the seamless steel pipe, so as to solve the problem that the outer surface of the existing seamless steel pipe is directly exposed and in direct contact with air or soil, which makes it easy to rust under the influence of air or soil, thus affecting the service life of the seamless steel pipe.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rust-proof nickel alloy seamless steel pipe, comprising a nickel alloy pipe and a protective pipe, wherein a support ring is installed on the outer surface of the nickel alloy pipe, a nylon ring is provided on the outer surface of the support ring, a protective pipe is provided on the outer surface of the nylon ring, and rubber plugs are installed at the gap positions between the protective pipe and both sides of the nickel alloy pipe by means of clamping buckles.

[0006] Preferably, the inner surface of the nickel alloy tube is provided with an anti-rust coating B, and the outer surface of the nickel alloy tube is provided with an anti-rust coating A.

[0007] Preferably, the nickel alloy tube and the protective tube are provided with plug grooves on both sides at the rubber plug positions, and the rubber plugs are fitted into the plug grooves.

[0008] Preferably, the clamping buckle has a positioning groove on one side, and the rubber plug has a positioning buckle at the positioning groove position, and the positioning buckle is fitted inside the positioning groove.

[0009] Preferably, the outer surface of the nickel alloy tube is provided with a groove at the position of the rubber plug, and the outer surface of the rubber plug is provided with a buckle at the position of the groove, the buckle being engaged inside the groove.

[0010] Preferably, a dryer is installed at both the top and bottom of the protective tube, and the dryer is filled with a desiccant.

[0011] Preferably, the dryer has a vent hole near the nickel alloy tube, and the vent hole has a vent mesh inside.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model achieves the effect of isolating and protecting the outer diameter of the seamless steel pipe by setting a protective tube and a rubber plug. This solves the problem that the outer surface of the existing seamless steel pipe is directly exposed and in direct contact with air or soil, making it prone to corrosion under the influence of air or soil, which affects the service life of the seamless steel pipe. This reduces the probability of corrosion of the seamless steel pipe and thus improves its service life.

[0014] 2. This utility model achieves the effect of supporting the protective tube by setting a support ring and a nylon ring, thereby solving the problem that the existing protective tube is not supported by a support structure and is prone to deformation during use, which can lead to deformation and damage of the seamless steel pipe. This improves the support effect of the protective tube and thus increases the service life of the seamless steel pipe.

[0015] 3. This utility model achieves the effect of dehumidifying and drying the connection point by setting a dryer, desiccant and vent holes, so as to solve the problem that the humidity at the connection point between the existing seamless steel pipe and the protective pipe is too high and cannot be dried in time, which makes the seamless steel pipe easy to rust and be damaged. It reduces the chance of corrosion of the seamless steel pipe and thus improves the service life of the seamless steel pipe. Attached Figure Description
