ASTM A105 Slip on Flanges Specification 

ASTM A105 Slip On Flange (SO flange) is a carbon steel Slip On Flange manufactured according to ASTM A105 standard and suitable for high temperature and high pressure pipeline systems. Its installation method is to put the flange directly on the pipe and then fix it with fillet welding. It is usually used in low pressure and non-critical applications.

ASTM A105 is the standard specification for carbon steel forging and is used in different piping applications. The ASTM A105 Carbon Steel Slip on Flanges is used in various fittings and valves with high-temperature services in a pressure system. 

A105 Flange Welding

These components can be welded. Welding procedures must comply with ASME Boiler and Pressure Vessel Code Section IX.

A105 Flange Heat Treatment

Heat treatment is not a mandatory requirement except for flanges above Class 300, flanges of special design where the design pressure or design temperature are not known and for items over 4” NPS and above Class 300. When heat treatment is required, annealing, normalizing, normalize and temper, normalize and quench and tempering shall be the applied methods.

A105 Flange Forging

This alloy is forged at between 1,700 degrees Fahrenheit and 2,200 degrees Fahrenheit, followed by quenching and tempering.

A105 Flange Annealing

Forged parts are allowed to cool to below 1,000 degrees Fahrenheit before reheating to between 1,550 degrees Fahrenheit and 1,700 degrees Fahrenheit. Slow furnace cooling follows.

Advantages

Cost-Effectiveness: 

Slip on flanges are generally less expensive than weld neck flanges.2 This makes them a budget-friendly option for many projects.

Ease of Installation:

Their design allows them to “slip” onto the pipe, simplifying the alignment process.3 This reduces installation time and labor costs.

Simplified Alignment:

The ease of alignment during installation is a significant advantage, particularly in field installations where precision can be challenging.

Versatility:

ASTM A105 carbon steel is a versatile material suitable for a wide range of applications, especially those involving moderate-pressure and high-temperature conditions.4

Availability:

These types of flanges are widely available from many different suppliers.

At 15th, August, we have received an order from Lebanese customer regarding EN1092-1 TYPE11 flange. They need 900 pieces in size: DN25. Pressure: PN16. Material: carbon steel. We delivered the goods quickly and provided quality inspection photos.

Types of EN1092-1 Flange

EN1092-1 flange include a variety of flange types. Such as TYPE01 plate flanges. TYPE02 loose plate flanges with weld on plate collar or for lapped pipe end. TPYE05 blind flanges. TYPE11 weld neck flanges, and so on. Each type has different dimensional requirements, such as flange diameter, flange thickness, bolt hole diameter, and bolt quantity.

Type No	Description	Flange Types
01	Plate flange for welding
02	Loose plate flange with weld-on plate collar or for lapped pipe end
04	Loose plate flange with weld-neck collar
05	Blind flange
11	Weld-neck flange
12	Hubbed slip-on flange for welding
13	Hubbed threaded flange
21a	Integral flange
32b	Weld-on plate collar
33 a,b	Lapped pipe end
34b	Weld-neck collar
35 b	Weldring neck
36b	Pressed collar with long neck
37b	Pressed collar

Scope of EN1092-1 Flange

Pressure range： PN 2.5, PN 6, PN 8, PN 10, PN 16, PN 25, PN 40, PN 63, PN 100；

Sealing surface：Type Flat Face (FF). Type B Raised Face (RF). Type C Tongue. Type D Groove. Type E Spigot. Type F Recess. Type G O-ring Spigot. Type H O-ring Groove.

Type 11 Flange

EN1092-1 TYPE11 flange is similar to American standard weld neck flange. Weld neck flanges are not easy to deform and are used in conjunction with bolts and gaskets. They have good sealing performance, corresponding rigidity and elasticity requirements, and reasonable welding thinning transition. 

EN1092-1 type11 flange is widely used in many industries, such as petroleum, chemical, pharmaceutical, etc.

Dimension of  PN16 Type11 Flange

Type 11 Flange Advantages

Durable connection.

Leakage prevention.

Ease of installation.

Testing of the pipe and joints are easier.

The flange face is kept away from heat affected area.

What is the Difference Between EN1092-1 and ASME B16.5 Flange

Standard

EN1092-1 is an important standard in the European flange standard system. It is mainly based on the German DIN standard, French NF standard, and British BS standard. EN1092-1 flange is widely used in Europe and countries and regions that adopt European standards.

ASME B16.5 is a standard developed by the American Society of Mechanical Engineers (ASME). This standard has been widely applied globally, especially in industries such as petroleum, chemical, power, and nuclear energy.

Application and Pressure

EN1092-1: covers multiple pressure levels with nominal pressures ranging from PN2.5 to PN100, as well as flanges with nominal sizes ranging from DN10 to DN2000.

ASME B16.5: Suitable for steel pipe flanges and their supporting components with nominal diameters ranging from 1/2 inch to 24 inches, with pressure ratings ranging from Class 150 to Class 2500 pounds (approximately corresponding to PN 10 to PN 420) to meet the requirements of different pressure environments.

Structural Form and Size

EN1092-1: Provides detailed specifications for the outer diameter, inner diameter, thickness, bolt hole position, quantity, and size of flanges, and provides strict tolerance ranges.

ASME B16.5 also specifies various structural forms and dimensional parameters of flanges, including WN(weld neck) , SO (slip on), BL (blind), SW (socket weld) and other types of flanges.
