Structural detailed solution of shell and tube heat exchanger The shell-and-tube heat exchangers mainly include structural types such as fixed tube-plate heat exchangers, floating-head heat exchangers, U-tube heat exchangers, and packing-type floating-head heat exchangers. The structure of the fixed-tube heat exchanger is simple. The low manufacturing cost can obtain a smaller shell inner diameter. The tube process can […]
A brief introduction to the inner and outer diameter micrometer of steel pipes
The outer diameter micrometer and inner diameter micrometer are the most used in the production and inspection process of steel pipes, precision steel pipes and seamless steel pipes. Today we will talk about the inner and outer diameter micrometers. 1. Outside diameter micrometer Micrometer outside diameter often referred to as micrometer, it is more precise than the […]
Why the seamless steel pipe should carry out the pickling process
In the rolling of seamless steel pipe, especially in the production process of seamless steel pipe, how does the pickling process go on, today it will open this mysterious veil for you immediately! Summary of seamless steel pipe pickling The method of removing oxide scale and rust from steel surface by acid solution is called acid […]
Application of stainless steel pipe in petroleum and petrochemical industry
1 Application of Stainless Steel in Petroleum and Petrochemicals The most commonly used classification of stainless steel is classified according to the structure of the steel and can generally be divided into ferritic stainless steel, austenitic stainless steel, martensitic stainless steel, duplex stainless steel, and precipitation hardened stainless steel. In petroleum and petrochemical applications, austenite stainless steel, […]
Welding method of long-distance pipeline
Long-distance pipeline welding method: First, manual welding (1) Arc welding of electrodes is sensitive and cumbersome, and has strong conformability. At the same time, due to the continuous improvement of electrode performance, its deposition efficiency and mechanical properties can still meet the requirements of today’s pipelines. In particular, welding welding is more commonly used. . The […]
Effect of solid solution process on stainless steel pipe fittings
The production cost of pipe fittings should be taken into consideration in the production enterprises of stainless steel pipe fittings, but the factors of preventing corrosion and improving the quality of the products should be taken into consideration. Therefore, it is necessary to adopt the solid solution process in the production process of stainless steel pipe fittings […]
A brief introduction to the production process of steel
The basic production process of iron and steel is to first obtain iron ore and coking coal and then to convert them into pig iron in an ironmaking blast furnace; the next step is to use pig iron as raw material, and use different steelmaking furnaces to smelt steel into steel; The shape of a […]
