The current processing status of red copper three-way pipe fittings in China

The red copper three-way pipe fittings have also followed the rapid development of China's economy and continuous innovation in science and technology. They are widely used in industries such as air conditioning, refrigerator refrigeration, shipbuilding, waterways, and petrochemicals due to their appropriate strength, excellent welding performance, easy shaping and processing, and good corrosion resistance. What is the current processing status of red copper three-way pipe fittings in China?

Selection of Copper Pipe Bend for Refrigeration of Purple Copper U-shaped Pipe Air Conditioner

The U-shaped copper pipe bend is the most widely used in pipelines, mainly used for bending and connecting pipelines. It is the most common in refrigeration pipeline systems, including various refrigeration products such as air conditioning, refrigerators, and cold storage. Due to the fact that pipelines are important transmission channels for transporting refrigerants, liquids, gases, etc., the quality and selection of copper pipe bends are very important.

Copper tube capillary welding method and steps for refrigerators

There are three main situations for the welding of copper pipes in refrigerators: the welding of copper pipes with the same diameter, the welding of copper pipes with different diameters, and the welding of copper capillaries and drying filters. The following will provide a detailed description of welding methods and steps for three different situations.

Reasons for water leakage in copper pipe fittings

The main reason for this is that the materials used in the production of copper pipes are different between China and foreign countries, because foreign standards emphasize the advantages of good welding performance, corrosion resistance, and high strength, while the materials used in China cannot achieve this;

Method of selecting copper pipes

Firstly, to distinguish the advantages and disadvantages of copper pipe fittings, we can observe them from their own perspective. On the outer surface, we can use some sharp objects to scrape them. If there is a deep line generated at this time, it indicates that it is good copper, because good copper pipe fittings are produced from pure copper, and the elongation of copper is very good. So this relatively good material is not graded and is used in military industrial production or some special industries;

Quality inspection of elbow welding

Appearance inspection: Generally, it is mainly observed with the naked eye, and sometimes observed with a 5-20 times magnifying glass. Through visual inspection, surface defects such as undercut, overlap, surface cracks, porosity, slag inclusion, and welding penetration can be found on the welded elbow weld seam. The external dimensions of the weld seam can also be measured using a weld junction detector or a template.

The advantages of stamping elbows

The production efficiency of stamping processing is high, and the operation is convenient, making it easy to achieve mechanization and automation. This is because stamping relies on stamping dies and stamping equipment to complete the processing. The travel times of ordinary press machines can reach dozens of times per minute, and high-speed pressure can reach hundreds or even thousands of times per minute. Moreover, each stamping stroke may result in a stamping part.
