Introduction:

With over 20 years of experience in the industry, our company, Shaanxi Peter International Trade Co., Ltd. has acquired rich expertise in producing carbon steel slip on flanges according to ASME B16.5 class 400 specifications.

As a reputable supplier, our company specializes in manufacturing high-quality ANSI/ASME B16.5 carbon steel slip on flanges Class 400. These flanges are designed to withstand higher pressure applications compared to Class 300 flanges, making them suitable for demanding industrial environments.

The ASME B16.5 standard ensures the dimensional accuracy, pressure ratings, and overall performance of your carbon steel slip on flanges. Class 400 indicates the higher pressure rating for these flanges, allowing them to handle elevated pressure conditions with efficiency and reliability.

By utilizing carbon steel as the primary material, your flanges possess excellent strength, durability, and resistance to corrosion. Carbon steel is known for its exceptional mechanical properties, making it a suitable choice for applications in various industries such as oil and gas, petrochemical, power generation, and more.

ASME B16.5 is a standard published by the American Society of Mechanical Engineers (ASME) that specifies the dimensions, materials, and pressure-temperature ratings for flanges and flanged fittings used in piping systems.

Slip-on flanges, as defined in ASME B16.5, are a type of flange that is designed to slip over the end of a pipe and then be welded in place. They are known for their ease of installation and alignment. 

Design: Slip-on flanges have a slightly larger inner diameter than the outer diameter of the pipe they are designed to fit over. The flange is positioned on the pipe and then welded both inside and outside.

Materials: They are available in a variety of materials, including carbon steel, stainless steel, and alloy steel, depending on the application and required corrosion resistance.

Pressure Ratings: Slip-on flanges are designed to handle various pressure ratings, which are specified in the ASME B16.5 standard. Common pressure classes include 150, 300, 400,600, 900, 1500, and 2500 pounds.

Installation: Slip-on flanges are ge​nerally easier and quicker to install compared to weld neck flanges because they do not require precise alignment of the pipe. However, the welds used in slip-on flanges may not be as strong as those used in other flange types.

ANSI/ASME B16.5 Class 400 Slip on Flanges:

The American Standard Slip on Flange class 400 is a commonly used pipe connection flange that conforms to US standards. It consists of two flange ends and an intermediate expansion joint. This type of connection can compensate for problems such as axial expansion, lateral displacement, and angular deviation in the pipeline system caused by temperature changes or vibration by sliding within the sleeve.

Carbon Steel Slip on Flanges are a type of slip-on pipe flange with a flat or raised face. This type of flange is machined with a ring groove, known as a "raised face" because the gasket surface is raised above the bolt circle face. In industrial process equipment applications, slip-on flanges with raised faces are most commonly used.

1.Dimensions are in millimeters(mm).

2.Dimensions can be specified by different purchasers.

3. For sizes 1/2’’-3.1/2’’, Dimensions of ASME B16.5 Class 400 Slip on Flanges are the same as ASME B16.5 Class 600 Slip on Flanges.

Carbon Steel Flanges and Stainless Steel Flanges:

1. Material Composition

Carbon Steel Flanges: Made primarily from iron and carbon. They may also include small amounts of other elements like manganese, silicon, and copper. The carbon content affects the steel’s strength and hardness.

Stainless Steel Flanges: Made from steel that contains chromium (at least 10.5%) and sometimes nickel. This composition gives stainless steel its corrosion resistance and durability. Common grades include 304 and 316.

2. Corrosion Resistance

Carbon Steel Flanges: Generally less resistant to corrosion and rust. They can be prone to oxidation and deterioration when exposed to moisture and harsh environments unless coated or treated.

Stainless Steel Flanges: Highly resistant to corrosion, rust, and staining. This makes them suitable for applications involving exposure to moisture, chemicals, and other corrosive elements.

3. Strength and Durability

Carbon Steel Flanges: Often stronger and harder compared to stainless steel flanges, particularly when treated or alloyed. They are suitable for high-pressure applications but may be less durable in corrosive environments.

Stainless Steel Flanges: Typically not as strong as carbon steel flanges but offer superior durability and resistance to wear and tear. They maintain their integrity in various environmental conditions.

4. Temperature Resistance

Carbon Steel Flanges: Can withstand high temperatures but may lose strength and become susceptible to oxidation at elevated temperatures.

Stainless Steel Flanges: Better suited for high-temperature applications due to their ability to maintain strength and resist scaling at high temperatures.

5. Cost

Carbon Steel Flanges: Generally less expensive due to the lower cost of raw materials and simpler manufacturing processes.

Stainless Steel Flanges: More expensive because of the higher cost of raw materials (especially chromium and nickel) and more complex production processes.

6. Maintenance

Carbon Steel Flanges: Require regular maintenance and coatings to prevent corrosion and extend their service life.

Stainless Steel Flanges: Require less maintenance due to their inherent resistance to corrosion and staining. They often need only periodic cleaning.

Features of Carbon Steel Slip On Flanges:

The American Standard Slip on Flange has several features and advantages:

Easy installation: The design of the slip on flange makes it easy to install and dismantle, making it suitable for situations that require frequent maintenance.

Low cost: Compared to other types of flanges, the slip on flange's cost is relatively low, making it an affordable choice.

Wide applicability: The American Standard Slip on Flange is suitable for many different piping systems, including those operating at low pressure and normal temperature conditions.

High reliability: With strict design and manufacturing standards, the American Standard Slip on Flange exhibits good sealing and connection reliability when in use.

High standardization: The slip on flange conforms to ANSI standards, ensuring a high degree of standardization and allowing for perfect matching with other piping and fittings that conform to the same standard.

The Most Common Materials of Carbon Steel Slip On Flanges:

A common and widely used material grade for carbon steel flanges is A105 forged carbon steel. They are designed to withstand temperatures ranging from ambient up to 1,000 degrees Fahrenheit and pressures between 20 to 6,170 psi. Carbon steel flanges are known for their wide temperature and pressure range, which makes them suitable for numerous industrial applications. Additionally, they are often chosen for their cost-effectiveness.

Modern carbon steel typically contains a carbon content of up to 2.1% by weight and is primarily alloyed with iron. The term "carbon steel" is sometimes used to refer to steel that does not have a significant amount of chromium or nickel. The carbon content in A105 flanges can vary, with a maximum allowable carbon composition of 0.35%. Increasing the carbon content in steel leads to increased hardness and strength, achieved through heat treatment processes such as quenching, tempering, and normalizing. However, as carbon steel is treated, it becomes less ductile and more brittle. This can make shaping and welding slightly more challenging. Despite this, the benefits of carbon steel in terms of its wide temperature and pressure range often outweigh the extra effort required for forming weld seals.

In terms of trace elements, A105 carbon steel flanges do not require any specified minimum content of alloy elements like molybdenum, nickel, chromium, titanium, or vanadium.
