Description

Covered pipe joint structure

This creation is related to an outer covering pipe, especially a joint structure of the outer covering pipe that is easy to install and not easily damaged after butt joint.

Generally speaking, the process liquid pipeline of the general workshop has been operated under high temperature, high pressure and high corrosive environment for many years. The cover pipe 10 is used to isolate the liquid pipeline from the external environment through the cover pipe 10, so that the temperature of the liquid pipeline can be maintained, and cracks, deformation and damage can be prevented. Especially when the liquid pipeline is subjected to pipe turning, high-frequency vibration and thermal expansion and contraction at the elbow position, it is more likely to cause heat loss, and increase the maintenance cost and the risk of pipeline corrosion. When the outer covering pipe 10 encounters a position where the pipeline needs to be bent, the outer covering pipe 10 will use the installation method as shown in FIG. 1 or FIG. 2 , please refer to FIG. 1 , which is composed of several tapered pipe bodies 11, a concave portion 111 is formed at one end of the tapered tube body 11, and a buckle portion 112 is formed at one end, and several tapered tube bodies 11 are stacked and arranged according to the curved shape of the pipeline, because the outer sides of the tapered tube bodies 11 are formed. It has an arc surface, so it can be adjusted according to the required angle. After the angle adjustment is completed, the buckle portion 112 of the tapered tube bodies 11 is then buckled in the concave portion 111 of the other tapered tube body 11 for fixing. The tapered pipe bodies 11; in addition, please refer to FIG. 2, which is another structure of the outer covering pipe joint 12, which is mainly formed by butting two semicircular outer covering pipe joints 12, There are several corrugated parts 121 at the bending part of the two outer covering pipe joints 12, through which the bending angle of the outer covering pipe joint 12 can be changed, and the pipeline can be wrapped in the Two outer covering pipe joints 12 .

However, the tapered pipe body 11 as shown in FIG. 1 needs to be installed from the extreme end of the liquid pipeline to the turning position, which is quite inconvenient to install. enter. Furthermore, with the structure formed by the tapered tube bodies 11, the connection between each adjacent tapered tube bodies 11 needs to be clamped and fixed, which is not easy to process on site and increases the difficulty of operation. In addition, the tightness of the snap connection is not good, and it is easy to create gaps during application, or due to vibration or position adjustment during use, resulting in gaps, and it is also easy for external liquids and other items to enter the interior through the gap, thereby causing Thermal energy loss or corrosion under the CUI (Corrosion Under Insulation) cladding layer; although the outer cladding pipe joint 12 in FIG. It is necessary to insert the two outer-coated pipe joints 12 from the end of the liquid pipeline, but the corrugated parts 121 formed by the bending of the pipe bodies of the two outer-coated pipe joints 12 are uneven. It is easy to be damaged by erosion or weathering, which relatively reduces its service life and strength. It is also easy for external liquids and other items to enter the interior through the damaged position, resulting in thermal energy loss or CUI (Corrosion Under Insulation) Corrosion under the coating In addition, the size of the outer covering pipe joint 12 needs to be processed and cut to length after on-site. After the cutting is completed, it can no longer be disassembled and used, and the cost of processing and use is relatively high.

The main purpose of this creation is to provide an outer-coated pipe joint structure, which is made of one-piece stamping, has a smooth surface and does not require on-site welding or cutting, improves service life and reduces assembly difficulty.

Another objective of the present invention is to provide an outer-coated pipe joint structure. The outer-coated pipe joint is formed by overlapping two symmetrical structures, which can be directly processed at the bend of the pipeline, and the operation is simple.

In order to achieve the above-mentioned purpose, this creation provides an outer-coated pipe joint structure, which includes: Two connecting pieces, which are in the form of one piece, have two connecting parts, and a turning part is formed between the two connecting parts, so that there is an angle between the two connecting parts; the connecting piece is connected to the connecting part along the connecting part. A semicircular tubular arc-surface concave portion is formed therebetween; after the two connecting pieces are butted, a circular accommodating space is formed between the two opposite arc-surface concave portions, and an opening is formed on the two connecting portions respectively.

The outer covering pipe joint structure provided by this creation, the two joints form a corner through the turning portion, so that the accommodating space formed between the two joints can cover a pipeline, and the two joints can be directly connected to the pipeline It can be applied at the bent position, which is convenient to operate; the turning part is a smooth arc, which is not easy to form corrosion in a specific position, which can relatively improve the service life; in addition, the two joints can be stamped and formed, which is easy to process and universal. High performance, can reduce inventory, and can be disassembled and used repeatedly, prolonging service life and reducing costs.
