Flange connection VS Wafer Connection: How to Choose the Best Pipe Connection Method?

In chemical pipeline systems, flange connection and wafer connection are two mainstream connection methods. When making a choice, a comprehensive consideration should be made based on specific working conditions, medium characteristics, cost budget and maintenance convenience. The following is a comparison of the two connection methods and selection suggestions:

Introduction and Principle of Threaded Flanges

Threaded flange refers to a type of flange that is connected to pipes by threads. It processes the inner hole of the flange into pipe threads and connects them with threaded pipes. It is a non-welded flange. Compared with flat welding flanges or butt-welding flanges, threaded flanges have the characteristics of convenient installation and maintenance, and can be used on some pipelines where welding is not allowed on site. Threaded flanges do not fall under high-pressure flanges. Their applicable pressure range is generally between 0.6 and 4.0Mpa, and the diameter is DN10 to DN150

The application of stainless steel flanges

Stainless steel flange is a common pipeline connection component, consisting of two interconnected annular parts (flanges) fixed together by bolts, with a hole in the middle for connecting the pipeline. It has a wide range of applications in multiple fields, and the following is a specific explanation of its application:

In which scenarios are eccentric size heads and concentric size heads respectively applicable

Eccentric reducers and concentric reducers each have their applicable scenarios in pipeline systems, mainly depending on the specific requirements and working environment of the pipeline system. The eccentric size header is mainly applicable to the following scenarios: Horizontally installed liquid pipelines: As one side of the eccentric reduction head is flat, this is conducive to exhaust or liquid discharge, especially when the pipeline system needs to be in

The applicable scenarios of large-diameter flanges

Large-diameter flanges refer to flange connection components with a relatively large nominal diameter (DN), which are typically used to connect pipes, valves, pumps and other equipment to achieve the transportation, distribution and control of fluids or gases. Its application scenarios are extensive, mainly depending on factors such as the pressure, temperature, medium characteristics of the pipeline system and the installation environment. The following are the typical application scenarios and key considerations of large-diameter flanges:

Flange sealing and leakage sealing treatment methods

Flange sealing and leakage sealing treatment are important links to ensure the safe operation of pipeline systems. The following is a detailed elaboration on the treatment methods of flange sealing and leakage sealing: First, French seal Flange sealing mainly relies on the tight connection between flange discs and the function of sealing gaskets. The following are several key elements to ensure the sealing performance of flanges: Selection of flange plates: Based on the pressure, temperature and medium characteristics of the pipeline system, choose the appropriate flange plate material and specification. Stainless steel flanges have become the first choice in many fields due to their excellent corrosion resistance and strength.

Production materials for flange covers

Flange covers, also known as blind plate flanges or blind plates, are flanges without holes in the middle, mainly used to seal pipe plugs. Its production materials are diverse, mainly including the following types: I. Carbon Steel Types: Including various models such as ASTM A105, 20#, Q235, 16Mn, etc. Features: The carbon steel flange cover has strong compressive strength and good elasticity, and is suitable for pipeline systems under various pressure and temperature conditions.
