Description

Technical Field

[0001] This utility model relates to a steel conversion component for connecting with an insulated fiberglass pipe. Background Technology

[0002] Insulated fiberglass pipes are widely used in many fields such as chemical engineering and water supply and drainage due to their advantages such as corrosion resistance and good insulation. However, when connected to steel pipes or equipment, conventional flange connections are prone to problems such as poor sealing and insufficient connection strength due to material differences, affecting the stability and sealing of the pipeline system. Chinese patent application number 202111482652.X discloses a method for integrating fiberglass pipes and steel flanges. The structure includes fiberglass pipes, waterproof rubber rings, steel flanges, steel hooks, and hand lay-up fiberglass. The fiberglass pipe and steel flange integration method directly connects the fiberglass pipes and steel flanges into one unit, improving installation efficiency. The design of reinforcing ribs and barbs improves the connection strength, and the rubber ring enhances the waterproof capability of the pipes, ensuring no leakage when the fiberglass pipes are connected to the flanges. Furthermore, the use of fiberglass pipes does not affect the compatibility of other metal fittings. However, this fusion method has some shortcomings in practical applications: glass-enclosed tubes made by hand lay-up of fiberglass are prone to defects such as bubbles and delamination during the curing process, and may experience problems such as loosening and falling off under long-term axial and radial forces, which in turn affect the sealing and strength of the connection.

[0035] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0036] like Figure 1As shown, this utility model provides a steel adapter for connecting to an insulated fiberglass pipe, comprising:

[0037] Adapter 1, which is a steel cylindrical structure;

[0038] Multiple annular sealing grooves 101 are spaced apart on the outer side wall of the adapter; the adapter is processed using steel of suitable strength and corrosion resistance, and the main body of the adapter and multiple annular sealing grooves that are compatible with the insulated fiberglass pipe are precisely machined to ensure dimensional accuracy and surface quality.

[0039] Multiple sealing rings, each corresponding to a detachable sleeve in multiple annular sealing grooves;

[0049] In summary, the steel adapter for connecting with insulated fiberglass pipes provided by this invention achieves a reliable and sealed connection between the insulated fiberglass pipe and the steel component, improves the connection strength and sealing performance, and ensures the stable operation of the pipeline system.

[0050] In a preferred embodiment, both stiffener I and stiffener II have triangular cross-sections.
