How to Connect Aluminum Pipe

In the complex system of ships, aluminum pipes, with their advantages of light weight and corrosion resistance, have become the key "blood vessels" for transporting various fluid media. How to accurately connect these aluminum pipes to ensure smooth fluid transmission, 90-degree aluminum elbows, aluminum tees and other aluminum pipe fittings have made an indispensable contribution.

Preparation before connection

Before connecting the ship aluminum pipe, we need to make full preparations. The first is to check the materials and accessories to ensure that the materials of the aluminum pipe and the aluminum 90 degree elbow, aluminum tee and other accessories meet the ship construction specifications, and there are no defects such as cracks and sand holes on the surface.

At the same time, it is necessary to prepare suitable connection tools, such as argon arc welding machines, cutting equipment, grinding tools, etc., and ensure that the tools are in good working condition. In addition, the connection parts of the pipes and accessories need to be cleaned to remove impurities such as oil stains and oxide films to prevent affecting the connection quality.

90 degree aluminum elbow

In the aluminum pipeline system of ships, it is often necessary to change the direction of the pipeline to avoid obstacles or meet the requirements of system layout. At this time, the 90 degree aluminum elbow comes in handy. It can realize the right-angle turn of the pipeline and ensure that the fluid maintains good fluidity when changing direction.

When connecting the 90 degree aluminum elbow, first align the aluminum pipeline with the connection port of the elbow, and use argon arc welding for welding connection. Before welding, evenly apply flux to the connection part to enhance the welding effect.

During the welding process, it is necessary to control the welding current and speed to ensure that the weld is uniform and full, and avoid welding defects such as pores and slag inclusions. After welding, the weld needs to be polished to make its surface smooth and reduce fluid resistance.

Aluminum Tee

Aluminum Tee is an important accessory for realizing pipeline diversion and confluence, and is indispensable in the aluminum pipeline system of ships. When it is necessary to divide a fluid into two or more streams, or to merge multiple streams into one, the aluminum tee can play its unique role.

When connecting the aluminum tee, first determine the installation position of the tee according to the direction of the pipeline and the needs of diversion and confluence. Accurately connect the aluminum pipeline with each interface of the tee, and also use argon arc welding for welding.

For diversion, it is necessary to ensure that the flow distribution of each branch pipeline meets the design requirements; for confluence, it is necessary to ensure that the fluid does not produce a large pressure loss at the confluence. After welding, the weld of the tee is fully inspected and quality tested to ensure that the connection is firm and reliable.

Other auxiliary accessories and connection points

In addition to 90-degree aluminum elbows and aluminum tees, aluminum flanges, aluminum straight joints and other accessories are also used for ship aluminum pipe connections. Aluminum flanges are often used in parts that need to be frequently disassembled or connected to pipes of different diameters. They are connected by bolts, and the sealing gaskets are used to ensure the sealing of the connection.

The connection of ship aluminum pipes is a systematic project. Various pipe accessories such as 90-degree aluminum elbows and aluminum tees cooperate with each other to build an efficient and stable pipeline network. Only by mastering the use and connection skills of these accessories and paying attention to every detail can a high-quality ship aluminum pipe system be created to escort the normal operation of the ship.
