Flanges are critical components used to connect pipes, valves, pumps, and other equipment in industrial piping systems. While most projects utilize standard flanges manufactured according to ASME, EN, JIS, or GOST specifications, there are numerous cases where custom solutions are necessary. These custom-made flanges, known as non-standard flanges, are designed to meet specific project requirements that standard flange dimensions, materials, or pressure ratings cannot fulfill. This article provides a detailed introduction to non-standard flanges, covering their definition, types, manufacturing process, applications, and advantages.

In the construction of piping systems, fittings are essential to ensure proper flow direction, branch creation, and system integrity. Among these fittings, the equal tee is one of the most commonly used and versatile components. It plays a significant role in branching pipelines and maintaining balanced fluid distribution, making it indispensable in industries such as oil and gas, water treatment, chemical processing, and HVAC systems.

This article explores the structure of the equal tee, its core functions, advantages, manufacturing standards, and industrial applications to provide a comprehensive understanding of why it is a preferred choice for many piping projects.

The global demand for cleaner energy has positioned liquefied natural gas (LNG) as a critical component of the modern energy mix. To effectively transport and store LNG, the entire supply chain—from production and liquefaction to shipping, storage, and regasification—requires components capable of withstanding cryogenic temperatures as low as -162°C.

Among these components, low-temperature flanges play an essential role in maintaining structural integrity and leak-free performance of critical connections. This article explores the applications of low-temperature flanges in LNG systems, covering materials, design standards, sealing considerations, and engineering challenges.

Choosing the correct bolt length for a flange connection is critical to ensuring proper sealing, mechanical integrity, and long-term reliability of piping systems. Bolts that are too short may fail to provide sufficient clamping force, while overly long bolts can interfere with surrounding equipment or cause uneven stress distribution.

This guide from Sunjin Metals Vina (SJM Vina) explains how to accurately select bolt length for flanges by considering industry standards, gasket thickness, washer usage, and installation tolerances.

In the realm of piping and flange systems, understanding Nominal Pipe Size (NPS) and Outer Diameter (OD) is essential for engineers, technicians, and procurement professionals. Confusion often arises when converting between NPS and OD, particularly when dealing with international standards, engineering drawings, or flange selection.

This detailed guide explains how to convert flange NPS to OD, why it matters, and how to avoid errors during flange sourcing and installation. Sunjin Metals Vina (SJM Vina) supports global customers with precise flange dimensioning, custom manufacturing, and expert technical consultation.

Steam systems are critical in industries such as power generation, chemical processing, food production, and heating networks. These systems operate under high temperatures and pressures, making the selection of components crucial for safety, reliability, and efficiency. Flanges play an essential role in steam service by connecting pipes, valves, and equipment. Choosing the right flange for steam applications ensures the system operates reliably under demanding conditions.
