Two examples of High strength metal pipe fittings

Nov 1, 2023 | Company News, News

There are many types of pipe fittings, and different types of pipe fittings have different functions. Some are used to connect pipes, some are used to change the direction of the pipes, some are used to change the diameter of the pipes, and some are used to increase pipeline branches. In the pipeline system, it is generally based on Appropriate fittings need to be selected. When selecting pipe fittings, you should also pay attention to the material of the pipe fitting. The material of the pipe fitting determines whether the pipe fitting can withstand high temperature, high pressure, corrosion resistance, etc. In other words, it determines whether the pipe fitting can be suitable for a certain work scenario.

In addition to the material of the pipe fitting itself, the processing method and processing procedures of the pipe fitting will also have a certain impact on the properties. In this article Fluidtech will introduce some knowledge about pipe fitting materials and processing methods.

A tight and high-pressure resistant pipe fitting

Forged pipe fittings are pipe fittings made by forging, that is, they are forged by impact force. The forging process uses forging machinery to exert pressure on the metal blank to cause plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. By continuously beating the pipe fittings, the original segregation, looseness, pores, slag inclusions, etc. in the steel ingot are compacted and welded, and the structure becomes tighter, improving the plasticity and mechanical properties of the metal.

Excellent benefits of forged pipe fittings

High strength and wear resistance: Forged pipe fittings are made of metal materials through cold/hot forging processes and have high strength and wear resistance. It can withstand loads under high pressure, high temperature and complex working conditions while maintaining structural integrity.So this kind of pipe fittings belongs to high pressure fittings.

Good dimensional accuracy: Forged pipe fittings have high dimensional accuracy and can meet engineering requirements. Through the forging process, more precise inner and outer diameters, wall thicknesses and lengths can be obtained to ensure that the connection between the pipe fittings and other parts is tight and firm.

Longevity: Forging eliminates potential porosity, shrinkage, cavities and cold pour issues.

Economical: It is generally believed that the forging process is very economical as no material is wasted.

Flexibility: The steel forging process is very flexible and can produce many different tube sizes.

An example of alloy steel pipes

Carbon steel press fittings is a pipe fitting made of carbon steel. Carbon steel refers to iron-carbon alloy steel with a carbon content of less than 2% (including 2%). Carbon steel can be further divided into low carbon steel, medium carbon steel and high carbon steel, mainly depending on the carbon content in the steel.

Mild steel (also called light steel): Carbon content usually ranges from 0.04% to 0.30%. Mild steel has good ductility and toughness, can be processed hot and cold, and is easy to weld. Commonly used low carbon steels include Q195, Q215, Q235, etc.

Medium carbon steel: The carbon content is usually between 0.30% and 0.60%. Medium carbon steel has higher strength and hardness, but lower ductility and toughness. Commonly used medium carbon steels include 45# steel, 40Cr, etc.

High carbon steel: Carbon content usually ranges from 0.60% to 2.00%. High carbon steel has high strength and hardness, but low ductility and toughness and poor weldability. Commonly used high carbon steels include 65Mn, T8, T10, etc.

Carbon steel press fittings also have the advantages of high strength, corrosion resistance, good stability and low cost.
