[0006] Preferably, the tube body can be tightly connected to the flange through a slot.

[0007] Preferably, the inner wall of the spiral structure is arranged at the inner wall position of the tube body.

[0008] Preferably, the arc-shaped guide plate can guide the water flow to move forward along the inner wall of the spiral structure.

[0009] Preferably, the inner wall of the spiral structure can change the flow pattern of water flow, and the inner wall of the spiral structure can guide the water flow to the inner position of the elbow.

[0010] Preferably, the elbow is made of three layers of material, and the galvanized inner layer is in direct contact with the water flow.

[0011] Preferably, the polyurethane middle layer is located at the inner middle position of the elbow to absorb the impact energy of water flow.

[0012] Preferably, the metal outer layer is in contact with the external environment.

[0013] Compared with the prior art, the present invention provides a galvanized seamless pipe for fire protection, which has the following beneficial effects:

[0014] 1. This device adopts a spiral structure inner wall at the inner wall position of the pipe body near the elbow, and an arc-shaped guide plate is provided on the right side of the spiral structure inner wall. The arc-shaped guide plate guides the water flow into the spiral structure inner wall when it flows. The spiral structure inner wall can reduce the turbulence and vortex of the water flow, so that the water flow passes through the pipe elbow more smoothly, thereby reducing the impact of the water flow on the elbow and the pressure loss.

[0015] 2. In order to increase the impact resistance of the elbow, the elbow is set to a three-layer structure. The inner layer is a galvanized inner layer for direct contact with water flow, which has good corrosion resistance and wear resistance. The middle layer is a polyurethane middle layer that can absorb and slow down the impact of water flow. The outer layer is a metal outer layer that can protect the polyurethane middle layer from the external environment. This can improve the performance and life of the elbow.
