Marking examples of A105 carbon steel slip on flange & blind flange
- ASTM A105 4 1/2” SO CLASS 150 RF manufacturer / supplier name & logo
- ASTM A105 4 1/2” Blind CLASS 300 RF manufacturer / supplier name & logo
CS A105 flanges p number
- P-number of 1 and Group number of 2
Calculate A105 blind flange thickness for hydrostatic testing
- t = d *(CP/SE+1.9W hg/SE*d^3) ½
Where,
- d= A105 flange diameter or short span
- E= Joint efficiency
- S= Maximum allowable stress value
- W= Total bolt load
- hg= Gasket moment arm
- P = Design pressure
- C = 0.3 From Fig UG-34(j)
So, here are few results using above formula
- 32″ SA105 blind flange thickness: 42.48 mm
- 36″ Killed carbon steel A105 forged flange thickness: 47.41 mm
- 38″ Carbon steel A105 Blank Flange thickness: 50.31 mm
- 44″ SA105n Blind Plate thickness: 54.19 mm
- 46 A105 forged steel blind flange thickness: 57 mm
- 48 CS ASTM A105 blind thickness: 59 mm
UNS K03504 ASTM A105 flange dimensions

Maximum size limit and weight of ASME A105n flanges

Advantages of astm a105 galvanized flange. Under which condition engineers use it?
- Galvanizing provides an additional layer of protection which enhances the corrosion resistance properties of the A105 carbon steel flange.
- The coating helps prolong the lifespan of the flange by preventing rust and deterioration.
- ASTM A105N and A105 galvanized flange are a cost-effective solution for applications where corrosion resistance is essential.
Engineers use ASTM A105 forged steel flange in conditions where they will be exposed to moisture, chemicals or other corrosive elements. Thus, they are mostly found in outdoor environments, marine applications and industrial settings.
What is the maximum size and pressure class of the SA 105 flange? Up to what temperature it can sustain?
The maximum size and pressure class of CS ASTM A105 blrf flange depend on the standards & specifications used for their design and manufacturing. Generally, they are available in sizes ranging from 1/2 to 48″ or larger. The pressure class can vary from 150 to 2500 or even higher and it depends on the design requirements.
SA 105 flange is used in temperatures ranging from -29°C to 538°C. The exact temperature depends on the specific pressure class and material properties
What is heat treatment? Heat treatment advantages of ASTM A105 carbon steel flange
Heat treatment is a controlled process used to alter the physical and mechanical properties of the material. The process involves heating the material to a specific temperature, holding it at that temperature for a certain duration and then cooling it at a controlled rate.
The advantages of heat treatment for forged A105 lap joint flange are:
- It can improve the ASTM A105 grade flange’s tensile strength and hardness.
- Improve the toughness and impact resistance of ASTM A105N flange.
- Enhance the wear resistance and lifespan of ASTM A105 steel flange along with reducing maintenance requirements.
- Heat treatment can relieve internal stresses in carbon steel ASTM A105 pipe flange.
- The process can improve the machinability.
- It refines the grain structure of the material
- It allows for precise control over the material properties.
What are ASTM A105N normalized flanges? In which conditions should you install them?
A105N normalized flange is A105 CS flange that have undergone the normalization heat treatment process. Herein, the flanges are heated to a specific temperature above their critical range and then air cooled to room temperature.
The normalized ASTM A105n carbon steel flange can be installed in the following conditions:
- High pressure and temperature systems
- Critical service applications
- Structural components with enhanced mechanical properties
- Petrochemical and refinery industries
Is there any cost and temperature rating difference between SA 105 flange and ASTM A105N flange?
A105N normalized flange may be slightly more expensive than standard flanges A105. The additional cost is due to the normalization heat treatment process, which enhances the mechanical properties.
A105N flange have a higher temperature rating than ASTM A105 forged steel flange
Experts advice to make Cost-effective ASTM A105 flange material
- Buy ASTM A105 sorf flange materials in bulk to get volume discounts from suppliers.
- Optimize the supply chain to reduce transportation and inventory costs.
- Promote standardization of CS ASTM A105 rf blind flange sizes and specifications to simplify production.
- Implement lean manufacturing principles to eliminate non value-added processes and increase productivity.
- Invest in automation and modern technologies to enhance production efficiency and reduce labor costs.
- Encourage a culture of continuous improvement to identify and implement cost-saving opportunities.
Which formula is best to calculate A105 flange weight chart?
The weight of ASTM A105 weld flange can be calculated by using the below formula:
Weight (W) = (OD – Thickness) x Thickness x 0.02466
Which origin is best to import A105 Flange in UAE?
The choice of the best origin to import flange wn A105 into the UAE depends on several factors. This will include quality, cost, lead time and supplier reliability. Some of the common origins to consider are:
- Indian manufacturers are known for producing high quality carbon steel ASTM A105 flange at competitive prices.
- China is a major exporter of SA105 steel flange and offers a vast selection of options at various price points.
- South Korean manufacturers adhere to quality and have advanced manufacturing capabilities.
- Some European countries produces premium quality ASTM A105 UNS K03504 flange, although they may be relatively more expensive.
Which quality testing and reports you should ask from your A105 flange manufacturer?
- Dimensional Inspection to verify the flange dimensions is as per the specified tolerances.
- Material testing certificates provide details about the chemical composition and mechanical properties.
- Pressure testing verify the flange ability to withstand the specified pressure ratings without leakage or failure.
- Non-destructive testing detects any surface or internal defects of ASTM A105 UNS K03504 forging.
- Certification and compliance ensure that the CS ASTM A105 flange is certified to relevant international standards.
- Request traceability information to identify the batch number of the A105 nace flange.
