A Comprehensive Guide To Die Forging

What Is Die Forging? Die forging is a forging method that uses a die on special die forging equipment to shape the blank and obtain forgings. This method produces forgings with precise dimensions, small machining allowances, and complex structures with high productivity. Characteristics of die forging In the die forging hammer or press with forging die will metal billet forging processing. Die forging process has high production efficiency, low labor intensity, accurate size, small machining allowance, and can forge complex shape forgings; suitable for mass production. However, the die cost is high, special die forging equipment is required, and it […]

What is a forged cylinder

The cylinder barrel is part of the steam engine containing the piston. Forged cylinders are generally stronger than cast cylinders and can withstand higher pressures without breaking. They are also much more durable than these two types because they do not wear quickly due to use or corrosion. Forging also makes it lighter and cheaper than casting cylinders, which is a huge advantage for small machinery manufacturers (such as agricultural equipment or construction machinery manufacturers). Forging workers use high temperature to transform liquid metal (usually iron) into different shapes, thereby forming finished products by high-pressure compression at high temperature. The […]

Selection of steel pipe wall thickness for high pressure and large diameter oi……

In the oil and gas pipeline transportation system, the reasonable selection of steel pipes for the pipeline can not only ensure the safety of pipeline transportation, but also save the capital investment in pipeline construction to a certain extent, because if the wall thickness and corrosion resistance can be selected reasonably, the final effective operation can be guaranteed and the corresponding investment will be reduced. Through the specific research on the selection of steel pipe wall thickness for high pressure and large diameter oil and gas pipelines, this paper promotes the relevant departments to be more scientific and reasonable in […]

Butt welding technology of nickel 201 plate

Nickel 201 is welded by manual argon tungsten arc welding. ERNi-1 welding wire with the same chemical composition and strength grade as nickel 201 is selected as the welding material. The physical properties of nickel 201 are characterized by low thermal conductivity, high expansion coefficient and poor weld metal fluidity. A larger V-groove and a groove angle of 70 ° should be used during butt welding. Small welding line energy and short arc welding shall be adopted in the welding process, and the interlayer temperature shall be less than 100 ℃. A series of tests shall be carried out after […]

Welding problems and solutions of pure nickel Ni201 plate

In the manufacture of a molten salt production reactor, the core component is a pure nickel NI201 plate with corrosion and high temperature resistance properties, and this process requires the welding of pure nickel materials. The weldability of pure nickel Ni201 is good, equivalent to chromium-nickel austenitic stainless steel, but the liquid weld metal fluidity is poor, its weldability is poor compared to carbon steel, need to develop a suitable welding process specifications to obtain a more good welded joints. In particular, the weld metal thermal cracking and porosity and welding heat-affected zone has a tendency to grain growth, which […]

Welding process of industrial pure nickel pipe

The weldability of pure nickel and its influencing factors were analyzed. Combined with the application in practical work, the welding process of industrial pure nickel pipe is discussed. On the basis of TIG welding, the self-made argon protective cover is used to avoid the serious oxidation of nickel in the high temperature area during welding. At the same time, combined with other protective measures and reasonable welding specifications, the welding quality of nickel pipe is obviously improved. The element nickel has a face-centered cubic lattice, which is characterized by a high melting point, corrosion resistance, high mechanical properties, good processing […]

Cause analysis of cracking of steel pipe in flattening test

In view of the fracture phenomenon of steel pipe made of strip steel in flattening test, the inclusion, grain size, microstructure, fracture and oxygen content of the fracture sample were inspected by XL30 scanning electron microscope and metallographic microscope. The results show that the main reasons for the flattening fracture are the large amount of inclusions and high oxygen content in the steel. For the fracture of steel tubes made of strip steel in the flattening test, the fractured specimens were examined for inclusions, grain size, organization, fracture and oxygen content analysis by using XL30 scanning electron microscope and metallographic […]
