Carbon Stainless Steel Welding Neck Wn Flange Rtj Class900 600 300

Product Data

Product Introduction

Common RTJ welding neck flange models include WN, SO, BL, LJ, TH, etc., with a pressure rating of typically 150 # -900#, suitable for pipeline systems in various fields such as petrochemical, fertilizer, papermaking, pharmaceuticals, food, etc.

Welding Neck RTJ flange refers to a type of welding neck flange connection method with a boss and circular groove. BS3293 is a standard specification used for the design and manufacturing of steel butt welded flanges. RTJ is the abbreviation for Ring Type Joint, which means ring gasket seal.

The Welding Neck RTJ flange usually consists of three parts: the flange itself, flange washer (RTJ washer), and fasteners such as bolts and nuts. This type of flange connection method uses butt welding to connect the flange to the pipeline, and uses RTJ gaskets to form a seal between the flange and the flange, thereby preventing fluid leakage.

Performance:

RTJ neck welded flange is a special flange connection method that uses a convex connection with a sealing ring, which can withstand high pressure and high temperature media, and has good sealing and seismic performance.

Dimensions:

The dimensions of RTJ neck welded flanges generally comply with ASME standards or European standards, such as ASME B16.5, ASME B16.47, EN1092-1, etc.

Pressure:

The pressure rating of RTJ neck welded flanges is generally 150 # -2500 #, and the specific pressure rating can be selected according to the usage requirements.

Usage:

RTJ neck welded flange is suitable for pipeline connections under high pressure and temperature. During installation, it is necessary to weld the flange and the end of the pipeline first, and then connect the two flanges and tighten them with bolts.

Applicable approach:

RTJ neck welded flange is suitable for medium transportation and treatment under high pressure and temperature in industries such as petroleum, chemical, pharmaceutical, aviation, aerospace, etc.

Advantages and disadvantages:

Advantages:

RTJ neck welded flange has good pressure resistance, high temperature resistance, corrosion resistance, and seismic performance. Adopting surface sealing connection, it has excellent sealing performance.

Disadvantages:

RTJ neck welded flanges require welding during installation, making installation difficult. During use, due to the presence of suspended and compressed forces between the flange and the pipeline, it is easy to cause stress concentration on the flange, thereby affecting its service life.
