[0002] Pipe fittings are a general term for parts used for connection, control, direction change, flow diversion, sealing and support in pipeline systems. Pipe fittings are widely used in engineering fields such as municipal administration, petrochemical industry, west-east gas transmission, shipbuilding and cable laying.

[0003] Chinese patent application number CN202110086586.8 provides a grooved lined stainless steel elbow, which belongs to the technical field of drinking water pipe connector manufacturing; the present invention comprises: an outer sleeve and an inner sleeve; the outer sleeve is a circular tube elbow structure; the inner sleeve has the same structure as the outer sleeve and is arranged in the outer sleeve; a filling layer is provided between the outer sleeve and the inner sleeve; slots are respectively provided at both ends of the outer sleeve; the inner sleeve is an integrated stainless steel elbow structure; the diameter of the elbow is D, and the radius of curvature of the elbow is R.

[0004] In the above technical solution, an integrated stainless steel bent pipe structure is used as the inner lining layer of the elbow, and a filling layer is adhered to the inner wall of the outer sleeve, which not only maintains excellent pressure-bearing and corrosion-resistant properties, but also has a smooth inner wall, which reduces the resistance to fluid passage. Traditional underground cable protection is usually wrapped with steel pipes or plastic pipes to prevent the cables from mechanical damage and environmental erosion. When the temperature changes, the underground cable protection pipeline will expand and contract due to heat, which will cause slight deformation of the sealing ring at the pipeline connection, and gaps may form after long-term accumulation. Once gaps appear, underground moisture, soil, etc. will penetrate into the pipeline, causing the cable to be immersed in muddy water, which will not only affect the performance of the cable, but may also cause damage to the cable, thereby affecting the normal operation of the entire communication system.
