Easy-to-connect stainless steel tubing assemblies

technical field

The utility model relates to the technical field of stainless steel pipes, in particular to an easily connected stainless steel pipe assembly.

Background technique

The steel pipe has a hollow section, and its length is much longer than the diameter or circumference of the steel. According to the cross-sectional shape, it is divided into circular, square, rectangular and special-shaped steel pipes; according to the material, it is divided into carbon structural steel pipes, low alloy structural steel pipes, and alloy steel pipes. and composite steel pipes; according to their uses, they are divided into steel pipes for transportation pipelines, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment, etc.; according to the production process, they are divided into seamless steel pipes and welding Steel pipes, of which seamless steel pipes are divided into two types: hot-rolled and cold-rolled (drawn), and welded steel pipes are divided into straight seam welded steel pipes and spiral seam welded steel pipes. Steel pipes are not only used to transport fluids and powdery solids, exchange heat, and manufacture mechanical parts and containers. It is also a kind of economical steel. Using steel pipes to manufacture building structure grids, pillars and mechanical supports can reduce weight and save metal by 20-40%. , and can realize factory-like mechanized construction. Using steel pipes to manufacture road bridges can not only save steel and simplify construction, but also greatly reduce the area of the protective layer, saving investment and maintenance costs.

304 is a general-purpose stainless steel, which is widely used to make equipment and parts that require good comprehensive performance (corrosion resistance and formability). 304 stainless steel is a grade of stainless steel produced according to the American ASTM standard. 304 stainless steel The rust performance is stronger than the 200 series stainless steel material, and the high temperature resistance is also better, which can be as high as 1000-1200 degrees. 304 stainless steel has excellent stainless corrosion resistance and good intergranular corrosion resistance. However, the outer surface of the existing stainless steel pipe is smooth, and it is cumbersome to connect and use. For example, threading is provided on the outer surface of the end of the existing stainless steel pipe, and then threaded connection is carried out through the pipe connector, but the process of threading is more complicated, and To a certain extent, the shape of the end of the stainless steel pipe is destroyed. If the outer wall of the pipe end is not threaded and connected directly through the pipe connector, the pipe is prone to prolapse, which will affect the normal use of the stainless steel pipe.

Utility model content

In order to overcome the existing above-mentioned deficiencies, the utility model provides an easy-to-connect stainless steel pipe assembly, which solves the problem by adding a tightening piece.

The technical scheme adopted by the utility model to solve the technical problem is: an easy-to-connect stainless steel pipe assembly, including matching stainless steel pipe sections and pipe connectors, adjacent stainless steel pipe sections are connected through pipe connectors, and the two stainless steel pipe sections Both ends are provided with connection bumps, the pipe connector is a cylinder with internal thread, the adjacent stainless steel pipe section is fixed and inserted in the pipe connector through the tightening ring, and the stainless steel pipe section is tightened by the connection bumps at both ends The grooves on the ring are inlaid and fixed.

Further, there are two sets of connecting projections and grooves, which are symmetrically arranged on the upper and lower sides of the stainless steel pipe section and the tightening ring.

Further, sealing rings are provided on opposite surfaces of the tightening rings on both sides.

Further, a gasket is provided on the mating surface connecting the protrusion and the groove.

Further, an isolation ring is provided at the center of the internal thread of the pipe connector.

Further, the ring width of the isolation ring is 1-3mm.

The beneficial effect of the utility model is that the connection and use of adjacent stainless steel pipe sections is carried out through a simple internal thread casing; the middle isolating ring divides the internal thread casing equally to facilitate the uniform connection of the stainless steel pipe sections on both sides; the tightening ring is convenient for smooth outer surface The connection and use of the pipeline can drive the tightening ring to adjust the position in the inner threaded sleeve through the embossing method of the concave and convex blocks.

Detailed ways

As shown in Figures 1 and 2, an easy-to-connect stainless steel pipe assembly includes matching stainless steel pipe sections 1 and pipe connectors 2. Adjacent stainless steel pipe sections 1 are connected through pipe connectors 2. Both are provided with connection bumps 3, the pipe connector 2 is a cylinder with internal threads, the adjacent stainless steel pipe section 1 is fixed and inserted in the pipe connector 2 through the tightening ring 4, and the stainless steel pipe section 1 is connected through the connection at both ends. The bump 3 and the groove 5 provided on the tightening ring 4 are inlaid and fixed, and there are two groups of connecting bumps 3 and grooves 5, which are symmetrically arranged on the upper and lower sides of the stainless steel pipe section 1 and the tightening ring 4, both sides A sealing ring 6 is provided on the opposite surface of the tightening ring 4, a sealing gasket 7 is provided on the mating surface connecting the protrusion 3 and the groove 5, and a spacer ring 8 is provided at the center of the inner thread of the pipe connector 2, and the spacer ring The ring width of 8 is 1~3mm.

When it is necessary to connect adjacent stainless steel pipe sections 1 for use, just insert the stainless steel pipe section 1 from both ends of the pipe connector 2, the smooth outer surface of the stainless steel pipe section 1 contacts the internal thread surface of the pipe connector 2, when the stainless steel pipe section 1 After touching the tightening ring 4 in the pipe connector 1, turn the stainless steel pipe section 1 to fine-tune the pipeline so that the connecting protrusions 3 at the upper and lower ends of the stainless steel pipe section 1 are just embedded in the groove 5 on the inner wall of the tightening ring 4, Then rotate the stainless steel pipe section 1 to drive the tightening ring 4 to rotate and extend into the internally threaded steel pipe until it reaches the spacer ring 8 in the middle of the pipeline connector 2, and the spacer ring 8 is fixed in the middle of the pipeline connector 2 by welding, and The spacer ring 8 is 1~3mm wide, so that the stainless steel pipe section 1 on both sides can be limited without affecting the normal connection of the pipeline, so that the pipes at both ends can be inserted at the same length, and the connection is stable and reliable. Tighten the ring 4 A sealing ring for buffering is bonded on the contact surface with the spacer ring 8 by superglue, and a sealing gasket 7 for strengthening connection and sealing is bonded on the embedding surface connecting the protrusion 3 and the groove 5 by superglue. The stainless steel pipe assembly is convenient and quick to disassemble and install, the connection effect is good, and it facilitates the connection and use of pipes with smooth surfaces that are not easy to fix. The installation of the connecting protrusion 3 at the end of the pipe will not affect the normal use of the pipe, but facilitates the placement of the pipe , to avoid the random rolling of the pipe after it is placed, and the connecting bump 3 forms a stable triangular shape with the ground, which is convenient for the pipe to be placed anywhere and has good placement stability.
