Carbon Steel Q235B ASTM A105 Lap Joint Flange

Product Introduction

Loose tube flange is a type of flange commonly used for pipe connections. It is usually used in pipeline systems and is also called loose tube flange.

Here is some basic information about loose tube flanges, including size, range, pressure rating, advantages, disadvantages, and features:

Dimensions and range:

Lap joint flanges generally fit standard pipe sizes, ranging from 1/2 inch to 24 inches. Can also be manufactured in larger or smaller sizes as required.

They are usually used to connect pipes made of different materials such as carbon steel, stainless steel, and alloy steel. The size of these flanges allows them to match a variety of pipe diameters, ensuring a tight connection.

Pressure Level:

The pressure rating of loose tube flanges usually meets standards such as ANSI B16.5 or DIN standards.

Common pressure levels include 150#, 300#, 600#, etc. Selecting the appropriate pressure rating depends on the operating conditions of the piping system, including temperature and pressure.

Advantages:

1. Easy installation: Loose sleeve flanges are easy to install as they only need to be slid onto the end of the pipe and then tightened with bolts and nuts, no welding or threading required.

2. Easy maintenance: This flange allows for easy disassembly and replacement of pipeline components, suitable for applications that require frequent repair or replacement of pipeline components.、

3. Provides a reliable sealing method, reducing the risk of leakage.

4. Suitable for pipes made of various materials, including carbon steel, stainless steel, alloy steel, etc.

Disadvantanges：

1. The performance of loose tube flanges in high temperature and high pressure applications may be limited because their sealing performance is relatively low and additional sealing packing or gaskets may be required.

2. Compared with some other flange types, loose flanges require more bolts and nuts to ensure the stability of the connection.

3. Carbon steel loose flanges usually require more bolts and nuts to ensure the stability of the connection, so they may require more maintenance.

4. In some applications, leakage may occur, especially under high temperature and pressure.

Features:

1. Loose flanges usually consist of two flanges, a set of bolts and nuts, and necessary sealing gaskets.

2. The connecting surface of the flange can adopt different shapes, such as flat welding flange, concave and convex flange, etc., to meet different pipeline connection requirements.

3. This flange type is suitable for a variety of industrial fields, including chemicals, oil and gas, pharmaceuticals, food processing, etc.

Overall, loose tube flanges are a common and versatile pipe joining device that are suitable for many different industrial applications. Selecting the appropriate size and pressure rating, as well as proper installation and maintenance, ensures the reliability and safety of your piping system.
