Application of ASTM A105 Slip On Flanges

Views: 2     Author: Site Editor     Publish Time: 2023-11-29      Origin: Site

ASTM A105 slip on flange refers to a flange that is connected to pipelines or valves using welding techniques. Slip on flanges can be divided into plate flanges and hub slip on flanges according to design characteristics. Slip on flanges, as a reliable connecting component, are widely used in the connection of medium and low pressure vessels and pipelines.

Characteristic of ASTM A105 Slip On Flange

ASTM A105 slip on flanges are made of high-quality carbon steel, with high strength, high toughness, and good corrosion resistance.Their connection principle mainly relies on welding, making the pipes more stable and securely connected together.

ASTM A105 standard is the material standard for slip on flanges, which specifies the material, performance and other indicators for manufacturing slip on flanges.This carbon steel material has good stability, good toughness and plasticity, and is the main raw material for forging flanges.In addition, due to its low carbon content, not exceeding 0.35%, it will not produce obvious pores and cracks during welding, making it more conducive to welding operations during pipeline connection.

Application of ASTM A105 Slip On Flange

ASTM A105 slip on flanges have excellent physical and mechanical properties and are widely used in pipeline systems in the petroleum, chemical, power, construction, and other industries.In pipeline connections, two pieces of slip on flanges are typically used with bolts and gaskets to seal the connection. One end of the pipeline is welded to the neck of the slip on flange to achieve the purpose of connecting the pipeline.

ASTM A105 slip on flanges are suitable for pipeline systems with relatively low pressure levels, where pressure fluctuations, vibrations, and shocks are not severe.Flat welding flanges not only save space and reduce weight, but more importantly ensure that the joint part does not leak and has good sealing performance.And it is cheaper than butt welding flanges, so it is widely used.

Manufacturing & Inspection

The manufacturing process of ASTM A105 slip on flanges includes material selection, cutting, forming, welding, heat treatment, inspection, and other steps.During the manufacturing process, key aspects such as material quality, welding quality, and heat treatment process need to be strictly controlled.At the same time, strict inspection must be conducted before leaving the factory to ensure that product quality meets the requirements of ASTM A105 material standards.

ASTM A105 slip on flanges, as a high-quality pipeline connecting component, are playing an increasingly important role in the industrial sector with their excellent performance and wide application.
