What are the difficulties in processing stainless steel pipe fittings?

What are the difficulties in processing stainless steel pipe fittings?

Since the beginning of the 21st century, due to the improvement of living standards, more than 30% of the residents in my country need high-end water pipes to meet their needs for high-quality life. Therefore, high-quality stainless steel materials have moved from high-end tableware to household water pipes. It has become a trend to use high-quality thin-walled stainless steel pipes in industrial or home decoration projects. Thin-walled stainless steel water pipes and stainless steel pipe fittings will become an indispensable part of the future building materials market.

Four forging forms of flange forging

Four forging forms of flange forging

Do you know about the four forging forms of flange forging? According to the movement form of mechanical flange forging, flange forging can be divided into oscillating rolling, oscillating forging, roll forging, cross wedge rolling, ring rolling and cross rolling. The die movement and degree of freedom of flange forging equipment cannot be controlled consistently, so flange forging can be divided into four forging forms. 1). Form of limiting forging force: Hydraulic press with hydraulic pressure directly driving the slider. 2) Quasi-stroke limitation method: Hydraulic press with hydraulically driven crank and connecting rod mechanism. 3) Stroke limitation method: a mechanical press in which the crank, connecting rod and wedge mechanism drive the slider. 4) Energy limitation method: spiral and friction press using spiral mechanism.

A brief discussion on how to reduce the wear of large flanges

A brief discussion on how to reduce the wear of large flanges

Do you know how you can reduce wear on large flanges? We share with you the following methods: 1. Correct mechanical design structure can help us reduce the pressure and wear between flange surfaces; 2. If the flange works in a dusty or polluted environment, dust-proof devices and sealing devices should be added; 3. Technically precise magnetic levitation supports can also be used to solve this problem; 4. The general method of reducing mechanical wear is to use lubricants. For flanges, fluid static lubrication and hydrodynamic lubrication can be used; 5. The material and heat treatment process of the flange also affect the overall quality of the flange; If you have other good methods, please share them with everyone!

Marine pipe fittings manufacturers talk about the types of pipe accessories commonly used on ships

Flange: Flange is an important component in pipeline connection and an essential part of pipeline connection. There are two main types of flanges used on ships: ordinary flanges and blind flanges. Ordinary flanges are mainly used for straight pipe connections, and blind flanges are used for pipeline closure and maintenance. Bolts: Bolts are important components for connecting flanges, and high-strength bolts are usually used. During use, you need to pay attention to the specifications, materials and tightening force of the bolts to ensure the reliability of the connection.
