Quality identification and installation method of ductile iron pipe
Ductile iron pipes have the characteristics of high strength, high pressure resistance, low accident rate, and long service time. But when we buy ductile iron pipes, how to distinguish the authenticity of ductile iron pipes? Next, I will briefly introduce how to distinguish ductile iron pipes. Th...Read more -
Casting you don’t know-the difference between 9 casting techniques
Die casting (die casting is an abbreviation of pressure casting) is a metal casting process that uses a mold cavity to apply high pressure to molten metal. Molds are usually made of higher-strength alloys. This process is somewhat similar to injection molding. Sand casting is the use of sand to m...Read more -

Recently, with the strong support of the National Defense Science and Industry Administration and China National Nuclear Corporation, the National Defense Science and Industry Administration’s nuclear energy development “Development of Nodular Cast Iron Spent Fuel Transport Containers”...Read more -
5 stages of precision mechanical parts processing
1. Roughing The main consideration is to increase productivity. Most of the machining allowance of each machining surface is cut off, and a fine datum is processed. 2. Semi-finishing It is mainly to remove the defects that may occur after rough machining, and to complete the processing of the se...Read more -

Anchorage in Prestressed Concrete
Anchorage as the name signifies is a component of post tensioning system which is used to anchor the tendons into the concrete while terminating or joining two tendons. Main function of anchorage is to transfer the stressing force to the concrete once the stressing process is completed. It is o...Read more -
What is post-tensioning?
A: At its most basic level, post-tensioning (PT) is a fiendishly clever way of reinforcing concrete while you are building – occasionally even allowing the construction of something which might otherwise have been impossible! The use of post-tensioning allows thinner concrete sections, longer s...Read more -

What are the casting parts
As I mentioned to you last week, I wanted to review what a casting was and this is part of a series of manufacturing disciplines that we do at UGS. Casting is a manufacturing process by which a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, a...Read more
