What are the size specifications and common connection methods of copper pipes?

Copper pipe is a widely used metal pipe products, in the construction, industry, power and other fields have a wide range of uses. Copper pipe has excellent thermal conductivity, corrosion resistance and mechanical properties, so it is widely used in some specific occasions.

The size specifications of copper pipe mainly include outer diameter, wall thickness and length. The outer diameter refers to the outer diameter of the pipe, and the wall thickness refers to the thickness of the pipe wall. Generally speaking, the outer diameter of copper tubes ranges from a few millimeters to several hundred millimeters, and the wall thickness ranges from tens of microns to several millimeters. The length of the copper pipe is generally customized according to user needs, and the common length is fixed length and coil length.

The common connection methods of copper pipe mainly include welding connection, socket connection and sleeve connection. The following describes the features and application scenarios of these connection modes.

Welding connection: Welding connection is the way to connect two red copper tubes to each other by melting metal materials. Common welding methods are butt welding, fillet welding, diagonal welding and so on. The welding connection has the characteristics of strong connection, good sealing, high temperature resistance, corrosion resistance, etc., suitable for high pressure, high temperature, important occasions, such as petroleum, chemical, pharmaceutical and other fields.

Socket connection: The socket connection is to insert the copper tube into the socket and make it tightly connected by external force. Connectors are generally divided into two types: pressing type and fastening type. The press type connector can be directly compressed by external force, while the tight type connector needs to be tightened by thread or nut. The socket connection has the characteristics of easy installation and maintenance, and is suitable for low pressure, cooling water, heating, air conditioning and other occasions.

Bushing connection: bushing connection is to put the copper tube into the bushing and fix it through the card clip. Sleeve connection has the characteristics of simple, fast, cost saving, etc., suitable for some one-time connection or temporary connection occasions, such as temporary water supply, parts assembly and so on.

In addition to the above common connection methods, there are some special connection methods, such as copper pipe crimping connection, copper pipe thread connection, etc. These connection methods can be selected according to the specific use environment and requirements.

In short, the size specifications and connection methods of copper pipes are diverse, and it is very important to choose the appropriate specifications and connection methods according to the specific use needs and environment. At the same time, pay attention to maintenance and maintenance during use to improve the service life and safety performance of copper tubes.
