Selection and analysis of stainless steel fasteners

There are many available to make the fasteners material, which are made of stainless steel fasteners not only the appearance of texture better, higher strength and better corrosion resistance, which can also better machining and welding, and stainless steel fasteners can be electroplated or heat treatment, in order to obtain higher performance, in addition to be 100% […]

The relationship between the material selection of stainless steel fasteners and the working environment

The normal working temperature of the heat exchanger is greater than 200 degrees, but sometimes the stainless steel bolts are easy to rust. The reason is that at high temperature, the thermal cycle will lead to some stainless steel models becoming non stainless steel. Therefore, stainless steel fastener materials must be chosen with caution. Contrary to general […]

Connection methods of stainless steel pipe fittings and their advantages and disadvantages

There are many ways to connect the stainless steel pipe fittings, the main ones are the pressure-type connection, the ring pressure connection, the flange connection, the groove connection, the welding connection and the taper thread connection. They are both good and bad, and in practice they need to find the best way. Compression coupling The connection […]

What are the surface anticorrosion methods of stainless steel screws

In all applications of stainless steel, stainless steel screws are a very inconspicuous but closely linked way of application. The stainless steel is a very excellent alloy metal. There are three main types of metal corrosion and usually can approach are composition design of contact surface of metal and metal dielectric properties, its application environment and external […]

Reasons and solutions for the locking of stainless steel fasteners

When fastening parts are used, the stainless steel fasteners will sometimes be locked. However, if the carbon steel fasteners are used, the locking is seldom seen. An important reason is that the stainless steel is soft and the carbon steel fasteners are relatively stiff. Stainless steel materials have good ductility, but there are some differences between hardness […]

Polishing and forming process of stainless steel pipe elbow

Generally speaking, there are three kinds of polishing processing technology for stainless steel pipe elbow, they are mechanical polishing, chemical polishing and electrolytic polishing. Among them, the machine polishing has three terms, need to understand, first of all, abrasive said is stainless steel pipe elbow polishing wax, eliminate excess particles, so that the surface shows very […]

The characteristics of three kinds of stainless steel pneumatic ball valves

Stainless steel pneumatic valve is made of stainless steel material with pneumatic actuator Pneumatic ball valve, although stainless steel is very much, but the most common stainless steel ball valves are basically made of 304 stainless steel, 316 stainless steel, the characteristics of the pneumatic ball valve is a strong corrosion resistance. A stainless steel pneumatic […]
