Introduction

There are two options for connecting pipes, valves and other components. One is flange connection, and the other is threaded connection. The two connection methods have different advantages and disadvantages. Below we will introduce the two connection methods in detail.

What is the difference between flanged and threaded connections?

Flanged connection is mainly used for connecting pressure vessels such as pipelines or valves. It is mainly connected by bolts, gaskets, etc., and is mostly used for connecting large-diameter pipelines. Flanges have different specifications and standards and can be used for different pipelines.

When should you use a flanged connection?

1. Flange connection is usually used when connecting large-diameter pipes.
2. Flange connection is required for connections in high-pressure environments.
3. Flange connection is used in pipes that need to be frequently disassembled for maintenance
4. Flange connection is used in corrosive pipe environments

When are threaded connections better?

Threaded connection is more suitable for small pipes and low-pressure systems, and is often used in indoor water pipes. Because the threaded connection is a part with threads, it can be screwed on directly.

What are the advantages of flanged connections?

1. Flange connection is resistant to high pressure, has high strength, and can withstand high pressure and high temperature environments.
2. Flange connection is easy to maintain and is beneficial for pipelines that need frequent inspection and maintenance.
3. Flange connection has higher sealing performance and can prevent leakage more effectively.

What are the limitations of threaded connections?

1. Not suitable for high pressure environment, threaded connection can withstand low pressure
2. Threaded connection has higher leakage, and it is easy to leak if it is not properly sealed
3. Low strength, only suitable for smaller pipe systems
4. It is difficult to disassemble after long use

How to decide between flanged and threaded connections?

First, determine whether the pipeline environment is high pressure or low pressure, and the size of the pipeline diameter. Whether frequent disassembly and maintenance are required.

Make a choice by referring to the difference between flange connection and threaded connection mentioned above.
