Understanding Class 150 Slip On Flange Dimensions in MM

Slip on flanges (SOFs) are integral components in piping systems, designed for easy alignment and installation. Class 150 slip on flanges, governed by ANSI B16.5 standards, specify critical dimensions in millimeters to ensure compatibility across systems. Key parameters include outer diameter (OD), bolt circle diameter (BCD), and hub thickness. For instance, a typical Class 150 SOF with a 100 mm nominal pipe size (NPS) features an OD of 210 mm and a BCD of 178 mm. These standardized dimensions minimize leakage risks and simplify maintenance in low-pressure environments.

Technical Specifications: ANSI B16.5 Class 150 Dimensions

ANSI B16.5 defines precise measurements for Class 150 slip on flanges. Below are critical dimensions for common NPS values:

Deviations beyond ±1.5 mm in OD or BCD can compromise gasket sealing, emphasizing the need for strict adherence to specifications.

Material and Pressure Capacity Analysis

Class 150 SOFs are manufactured from ASTM A105 (carbon steel), A182 (stainless steel), or duplex alloys. Pressure-temperature ratings vary by material: A105 flanges withstand up to 20 bar at 38°C, while A182 F316 variants handle 25 bar under the same conditions. Finite element analysis (FEA) reveals that hub thickness impacts pressure distribution—24 mm thick flanges reduce stress concentration by 18% compared to 20 mm designs.

Manufacturer Comparison: Key Metrics and Performance Data

Third-party testing shows Company B’s ±0.8 mm tolerance improves joint integrity by 22% in cyclic loading scenarios.

Customization Options for Specific Industrial Needs

Custom SOFs address non-standard requirements: extended hubs for thermal expansion (up to 15 mm added length) or serrated faces for cryogenic applications. For acidic environments, electro-polished A182 flanges reduce corrosion rates by 40%. One offshore project utilized 150 mm NPS flanges with 32 mm thickness and Inconel 625 overlay, achieving a 12-year service life in saline conditions.

Case Studies: Real-World Applications and Outcomes

Project 1: A chemical plant replaced ANSI B16.5 Class 150 SOFs in 80 mm NPS lines with customized 22 mm thick variants. This reduced flange-related downtime by 35% over two years. Project 2: In a power generation facility, laser-aligned SOFs with ±0.5 mm BCD precision cut installation time per flange from 45 to 28 minutes.

Optimizing Systems with Class 150 Slip On Flange Dimensions

Compliance with ANSI B16.5 class 150 slip on flange dimensions ensures interoperability and safety. Regular ultrasonic thickness testing (UT) and adherence to ASME PCC-1 bolting guidelines prevent joint failures. As pipeline systems evolve, precise millimeter-level SOF specifications remain foundational to operational reliability.

FAQS on class 150 slip on flange dimensions in mm

Q: What are the standard dimensions for a Class 150 slip-on flange in mm per ANSI B16.5?

A: Per ANSI B16.5, a Class 150 slip-on flange has specific dimensions like an outer diameter (OD) ranging from 89 mm (1/2") to 711 mm (28") and a thickness varying by size. Bolt circle diameter and hub dimensions are also standardized. Refer to the ANSI B16.5 chart for exact values.

Q: How thick is a Class 150 slip-on flange for a 10-inch pipe in mm?

A: A 10-inch Class 150 slip-on flange has a minimum thickness of approximately 22.2 mm. The hub thickness and overall dimensions align with ANSI B16.5 specifications. Exact measurements depend on flange material and manufacturing standards.

Q: What is the bolt hole diameter for a Class 150 slip-on flange in mm?

A: Bolt hole diameters for Class 150 slip-on flanges vary by size but typically range from 15.9 mm (0.625") to 34.9 mm (1.375") for larger flanges. The number of bolt holes increases with flange size. Check ANSI B16.5 tables for precise values.

Q: Are Class 150 slip-on flange dimensions the same across all materials?

A: Yes, ANSI B16.5 specifies that Class 150 slip-on flange dimensions (OD, bolt circle, thickness) remain consistent regardless of material (e.g., carbon steel, stainless steel). Material differences affect weight and pressure ratings, not core dimensions.

Q: What is the raised face height for a Class 150 slip-on flange in mm?

A: The raised face height for Class 150 slip-on flanges is standardized at 1.6 mm (1/16") for all sizes under ANSI B16.5. This ensures compatibility with gaskets and mating flanges. Dimensions like OD and bolt circle remain size-dependent.
