Description

Technical Field

[0001] This utility model relates to the field of pipeline support equipment technology, and in particular to a phenolic composite insulated pipe support and modular support structure. Background Technology

[0002] Pipe supports are key components of pipeline support systems. They are mainly used to support pipelines and limit their displacement, ensuring the stability of pipelines during operation. They play an indispensable supporting and protective role in fields such as petrochemicals, heat transmission, and refrigeration engineering.

[0003] However, traditional pipe support structures have the following defects: (1) severe thermal bridging effect, the direct contact between the metal pipe support and the pipe will cause the heat loss of the support part to exceed 15%; (2) the insulation layer is easily damaged, the pipe vibration will cause the insulation material of the pipe support part to be squeezed, deformed or cracked; (3) poor corrosion resistance, the metal support will rust in the humid environment, reducing the service life; (4) difficult to install and adjust, the fixed structure is difficult to adapt to the thermal expansion and contraction displacement of the pipe.

[0004] It is evident that the issue of load-bearing and insulation coordination in pipe support components remains a pressing problem that needs to be addressed in this field. Utility Model Content

[0005] To solve the technical problem of load-bearing and heat insulation coordination in pipe support, this utility model provides a phenolic composite heat-insulating pipe support, including a load-bearing base and a phenolic insulation layer that are movably connected by an interlocking structure.

[0006] The fitting structure includes a fitting recess and a fitting protrusion, which are respectively provided on the contact surface of the load-bearing base and the phenolic insulation layer;

[0007] The upper groove of the phenolic insulation layer is also provided with an enhanced protective layer.

[0008] In one embodiment, the load-bearing base is made of galvanized steel or fiberglass, with an arc-shaped groove surface on the top and an internal irregular anti-slip rubber pad; the thickness of the load-bearing base is 3 mm to 450 mm.

[0009] In one embodiment, the phenolic insulation layer (30) is made of closed-cell phenolic foam with a thickness of 30 mm to 80 mm and a density of 80 kg / m³. 3 ~120 kg / m 3 The compressive strength is ≥0.8 MPa; wherein the phenolic foam has adhesive properties during foaming and can directly bond the upper reinforcing protective layer.

[0010] In one embodiment, the reinforcing protective layer comprises basalt fiber cloth and flame-retardant epoxy resin, with a thickness of 1.5 mm to 3 mm.

[0011] In one embodiment, the reinforced protective layer further includes a fluorocarbon coating layer, which is directly coated with fluorocarbon coating and then hardened.

[0012] In one embodiment, the phenolic composite insulation pipe support further includes an anti-slip rubber pad disposed on the upper layer of the reinforced protective layer.

[0013] In one embodiment, the fitting recess is a dovetail-shaped groove, and the fitting protrusion is a dovetail-shaped protrusion.

[0014] In one embodiment, the fitting recess is provided on the groove surface of the load-bearing base, and the fitting protrusion is provided on the flange surface of the phenolic insulation layer.

[0015] This utility model also provides a modular support structure for supporting the phenolic composite insulation pipe support as described above, including a height adjustment module and a cold bridge prevention structure.

[0016] The height adjustment module includes several threaded outer tubes and threaded inner tubes arranged in sets. The top end of the threaded outer tube is connected to the load-bearing base, and the bottom end of the threaded inner tube is connected to the external support column.

[0017] The height adjustment module also includes a rotating buckle and a locking nut. The rotating buckle is located at the bottom of the threaded outer tube, and the locking nut is located on a through screw hole on the side wall of the rotating buckle.

[0018] The anti-cold bridge structure is a heat insulation gasket, which is sleeved on the threaded outer tube.

[0019] In one embodiment, the height adjustment range of the height adjustment module is ±50 mm; the heat insulation pad is a calcium silicate heat insulation pad with a thermal conductivity ≤0.05 W / (m·K).

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The phenolic composite insulated pipe support provided by this utility model integrates high-strength support and ultra-low thermal conductivity, effectively eliminating the thermal bridging effect and solving the technical problem of load-bearing and insulation coordination in the pipe support area. The load-bearing base and the phenolic insulation layer are connected by a dovetail-shaped interlocking structure for rapid assembly and disassembly, with a single-point installation time of ≤10 min. It can also accommodate radial displacement of the pipe by ±20 mm, greatly improving installation efficiency. A reinforced protective layer composed of basalt fiber cloth and flame-retardant epoxy resin provides synergistic strength support and can be further coated with fluorocarbon paint to form a fluorocarbon coating layer, enhancing the structure's corrosion resistance. Furthermore, a height-adjustable modular assembly is achieved through a height adjustment module, increasing its applicability in vertical space.

[0022] In summary, the phenolic composite insulation pipe support and modular support structure provided by this utility model integrate the advantages of high strength support, ultra-low thermal conductivity, vibration resistance and durability, acid and salt resistance and rapid installation, and are suitable for petrochemical, LNG transportation, heat pipeline network and other scenarios.

The fitting protrusion 31 is a dovetail-shaped protrusion provided on the flange surface of the phenolic insulation layer 30.

[0037] During installation, align the fitting protrusion 31 with the fitting recess 11 from the notch side and push it to the opposite side until it touches, thus completing the fitting installation of the load-bearing base 10 and the phenolic insulation layer 30.

[0038] The upper groove of the phenolic insulation layer 30 is also provided with an enhanced protective layer 40.

[0039] The upper layer of the reinforced protective layer 40 is also provided with an anti-slip rubber pad 50;

[0040] During installation, the anti-slip rubber pad 50 is placed directly into the groove on the upper part of the reinforced protective layer 40.
