Carbon steel large diameter flange

Carbon Steel Large Diameter Flange Introduction

Carbon steel large diameter flanges, also known as large diameter flat welding flanges made of carbon steel, are also referred to as large diameter flat welding flanges, large flat welding flanges, etc.

Large diameter flanges, as the name implies, are flat weld flanges designed for use with large diameter pipes.

Large diameter flanges are primarily machined using CNC lathes, semi-automatic lathes, and drilling machines.

Material Categories

Materials can be categorized into carbon steel, alloy steel, stainless steel, etc.

Material mainly includes carbon steel flanges, such as Q235, Q345, 20#, 16Mn, etc.

Standard Practices Commonly Implemented

Flat Plate Welding Steel Pipe Flange - GB9119

Raised face flat welding steel pipe flange - GB9119

Flanged Welding Steel Pipe Fitting - GB9116

Convex Neck Welding Steel Pipe Flange - GB9116

Flange Packaging

Large diameter flanges for export are typically packed in wooden crates or shock-absorbing film.

Application Fields

Chemical, power, wastewater, wind power, municipal, aerospace, and nuclear industries all utilize large-diameter flat-welded flanges where there are large pipelines or pressure vessels.

Procurement Recommendations

1: Recommend purchasing from a legitimate flange manufacturer, which should have a certain scale of production.

2: Manufacturers of flanges must provide material inspection reports and relevant documents for flange plates.

3: Flange plates must have corresponding specification and model embossed markings and identification.
