Sinton Group Launches High-Performance Industrial Flange Series

——Reliable Pipe Connections for Safer and More Efficient Heating Systems

In industrial heating systems, pressure vessels, and process piping applications, flanges play a critical role in ensuring structural integrity and leak-free connections. Leveraging extensive experience in electric heating equipment manufacturing, Sinton Group proudly announces the launch of its comprehensive industrial flange product line, designed to meet global engineering standards and demanding operating conditions.

Comprehensive Flange Types for Diverse Applications

Sinton Group provides a full range of industrial flanges, including:

Slip-On Flange (PL)

Weld Neck Slip-On Flange (SO)

Weld Neck Flange (WN)

Socket Weld Flange (SW)

Blind Flange (BL)

Long Weld Neck Flange (LWN)

Each flange type is engineered for specific pressure ratings and installation environments, making them ideal for electric heaters, thermal oil systems, heat exchangers, pressure pipelines, and petrochemical facilities.

International Standards Compliance

To ensure seamless integration into global projects, Sinton Group flanges are manufactured in strict accordance with:

HG/T 20592 (European System)

HG/T 20615 (American System)

Custom production available per GB, JB, SH, and other international standards upon request

Our flanges are precisely manufactured based on nominal diameter (DN), pressure rating (PN/Class), facing type, and material grade to meet diverse engineering requirements worldwide.

Multiple Sealing Face Options for Enhanced Tightness

Sinton Group offers various flange facing types, including:

Raised Face (RF)

Male Face (M)

Female Face (FM)

Tongue (T)

Groove (G)

Selecting the appropriate sealing surface improves sealing reliability, minimizes leakage risks, and ensures stable performance in high-temperature, high-pressure, and corrosive environments.

Technical Advantages

1. Optimized Structural Strength

Weld neck flanges feature a tapered hub design that ensures smooth stress transition from pipe to flange, making them suitable for high-pressure and high-temperature conditions.

2. Strict Material Control

Available materials include Carbon Steel (20#), Stainless Steel 304, 316, 310S, and other special alloys to meet different corrosion and temperature requirements.

3. Precision CNC Machining

Advanced machining processes guarantee dimensional accuracy and superior sealing surface finish, enhancing installation efficiency and operational safety.

4. Perfect Integration with Heating Equipment

With strong expertise in industrial electric heating systems, Sinton Group flanges are fully compatible with flanged immersion heaters, thermal oil heaters, and heat exchanger assemblies.

Typical Applications

Oil & Gas Pipeline Systems
