Many businesses prefer the fact that Inconel 600 is a very versatile alloy. Therefore the alloy is used in several key industries in various forms including the popular Inconel 600 Pipe. The construction of these pipes could be either welded or they could be seamless. There are benefits to using both. For e.g. the preference of an Inconel 600 Welded Pipe, is in applications where its economics plays a very important role. Though cheaper than the seamless constructed one, these pipes have a longitudinal seam, which could become susceptible to intergranular corrosion – if they are improperly processed. In a scenario, where the buyer requires the highest form of corrosion resistance and the ability to withstand a higher pressure, Inconel 600 Seamless Pipe is the best option.

Flange is the parts which connects two pipe ends, flange connection is defined by the flange, gasket and bolt three are connected as a group of combined sealing structure of the detachable connection. The gasket is added between the two flanges and then fastened by bolts. Different pressure flange, thickness is different, and the bolts they use are different, when pump and valve connect with pipe, the parts of the equipment are also made of the corresponding flange shape, also known as flange connection, usually closured bolted connection parts are also known as flanges, such as the connection of ventilation pipe, this kind of parts can be called “flange type part”, but this connection is only part of a device, such as the connection between flange and water pump, it’s not inapposite to call water pump as flange type parts,but relative small valve,it can be called as flange type parts .

Stainless Steel 304 Flanges are components that are used to connect pipes together. They differ from the fittings in that all flanges have an outward projection from them that provides additional space for attachment such as welding or bolting. Roopam Steel is a manufacturer and leading supplier of these flanges.

SAE 304 stainless steel is the most common stainless steel. The steel contains both chromium (between 18% and 20%) and nickel (between 8% and 10.5%)[1] metals as the main non-iron constituents. It is an austenitic stainless steel. It is less electrically and thermally conductive than carbon steel. It is magnetic, but less magnetic than steel. It has a higher corrosion resistance than regular steel and is widely used because of the ease in which it is formed into various shapes.[1]

Flanges made of stainless steel are called “stainless steel 304 flanges”, also referred to as “SS 304 flanges”. Common material standards and grades include ASTM A182 Grade F304/L and F316/L, with pressure ratings of 150 to 2500 and 300 to 600, respectively.

Stainless steel 304 flanges are a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also facilitates cleaning, inspection or modification. Stainless steel 304 flanges are made from the 18/8 chrome-nickel austenitic stainless steel alloy most used in stainless steel applications.

At moderate temperatures, SS 304 flanges can also provide good performance in aggressive solutions, especially those that do not contain chlorides or fluorides. While Grade 304 performs well in fresh water applications with low chloride levels (i.e. less than 100 parts per million), exposure of the alloy to higher chloride levels makes UNS S30400 304 stainless steel flanges susceptible to crevice and pitting corrosion Impact.

There are different types such as A182 F304 SORF flange which is a slip on raised face flange. Slips on flanges are suitable for use with seamless pipe to create precise connection locations. The raised face of the flange provides an additional surface for welding or bolting. The SS 304 WNRF flange is a butt weld raised face flange. Raised faces help with connection, while welded necks provide extra grip to hold pipes in place. Flanges range in size from ?” to 48″ in diameter.

ASME SA182 304 stainless steel flanges have a minimum of 18% chromium, 8% nickel and a maximum carbon content of 0.08%. UNS S30400 SS flanges are defined as chromium-nickel austenitic alloys. Meanwhile, grade 304 is the standard “18/8” stainless steel you might see in pans and cooking tools. We supply these SS SUS 304 Pipe Flanges on custom request to our valued customers.

This specification includes flanges for pressure vessel grade applications. The material has good strength and general corrosion resistance, high operating temperature. The minimum yield strength of 304 stainless steel flange is 215MPa, and the minimum tensile strength is 505MPa.

The material can withstand temperatures up to 870 degrees Celsius. There are different types of flanges such as SS 304 slip flange for precision applications of seamless pipes. Flanges are available in nominal bore diameters from ?” to 48″. There are also different pressure classes in A182 F304 flanges, ranging from 150 to 2500, also known as pressure numbers. Pressure values vary from PN6 to PN64.

RFWN flanges (raised face weld neck flanges) are one of the most commonly used flanges in the plumbing industry. Their long tapered hub matches the wall thickness (hole) of the pipe and is easy to identify.

Weld butt flanges and long butt weld flanges provide reinforcement in applications requiring high pressure and in extreme low and high pressure situations. It also helps address low cycle fatigue caused by otherwise variable force linear expansion.

Weld flange holes are machined to match the ID of the pipe or fitting. This creates a smooth transition between weld neck flanges and prevents turbulence at the weld neck. Therefore, it is important to specify a piping plan when purchasing butt weld flanges. Butt weld flanges are welded to the pipe with a full penetration weld and provide excellent stress distribution through the tapered neck. In critical applications, welds are also often radiographically or UT inspected.

Butt weld flanges are available in both raised and flat configurations. The most common butt weld flanges have standard holes or extra heavy holes. Sch 120 or Sch 160 hole flanges, heavier weights such as 600# to 1500#, are also common in butt weld flanges. HT PIPE sells a wide range of butt weld flanges in A105, A105N, stainless steel, duplex and super duplex steels and nickel alloys.

There are no gaps or grooves that could lead to crevice corrosion. Conical necks are also known as “nozzle necks” or more commonly “high hubs”. Although expensive, butt weld flanges are the best designed butt weld flanges because the long tapered hub provides excellent strength and dent resistance.

According to ASME B16.5, the hub of the butt welding flange can be roughly divided into a tapered part and a straight long part. The processing straight length is 6mm, which is precisely matched with the adjacent pipes, which is convenient for welding. Butt weld flanges are drilled to match the inside diameter of the adjacent pipe. The thinner the pipe wall, the larger the hole through the flange. The thicker the wall, the smaller the hole. Because of these matching relationships, there are no restrictions on traffic. Turbulence and erosion are thus eliminated.

ASME B16.5 Butt Weld Flanges shall be equipped with cut square heads when wall thicknesses are less than 5mm, and shall be provided with flat beveled ends when wall thicknesses are from 5mm to 22mm (inclusive), or when wall thicknesses are greater than 22mm Should be equipped with compound beveled end mm. Butt weld ends shall be machined in accordance with ASME B16.25.

Stainless Steel Raised Weld Face Flanges for blocking the ends of piping systems or valves. The raised face is designed to concentrate more pressure into a smaller area on the flange, providing enhanced sealing capability at higher pressures. Butt weld flanges are also designed to match the inside diameter (ID) of the connecting pipe. This flange is ideal for high pressure, high temperature and sub-zero temperature applications. This flange is inserted and welded to the connecting pipe.

As the name suggests, alloy steel butt weld flanges are welded to the bottom of the pipe. Flange holes match pipe holes, allowing undisturbed product flow and reducing turbulence and erosion at joints.

Stainless steel butt weld flanges are widely used in high pressure applications where they provide support strength and stress distribution. While ASME B16.9 butt weld flanges can be radiographed for flaw detection and are very durable.

A butt weld flange is a steel flange designed to transmit stress to the pipe to reduce high stress concentrations at the bottom of the flange. Compared to other types, butt weld flanges are distinguished by their tapered hub and smooth transition from flange thickness to pipe wall thickness. They are resistant to deformation and are typically used in high pressure piping systems, high or low temperature conditions.

The weld bevel is attached in a V-joint to the pipe end with a similar bevel, which allows for a uniform circular weld around the perimeter for a uniform transition. This allows gas or liquid within the piping assembly to flow through the flange connection with minimal restriction. Check the welded bevel connection after the welding procedure to ensure that the seal is uniform and free of abnormalities.

Another distinctive feature of butt weld flanges is the tapered hub. This type of connection provides a more gradual pressure distribution along the transition from the pipe to the bottom of the flange, helping to withstand some of the shock that occurs when used in higher pressure and higher temperature operating environments. Mechanical stress is limited considering the extra steel that transitions along the hub.

Since higher pressure ratings almost exclusively require this type of flange connection, butt weld flanges are usually made with ring joint faces (also known as RTJ faces). This sealing surface allows a metal gasket to be crushed between the grooves of the two connecting flanges to create an excellent seal and complement the high-strength welded bevel connection to the pressurized piping assembly. RTJ weld necks with metal spacer connections are the primary choice for critical applications.

Long butt weld flanges, also known as nozzle flanges or “long neck” flanges, are designed for the pressure vessel and tank manufacturing industries. They are usually made in one piece and are designed to replace standard weld neck and pipe weld combinations. The lack of the necessary welded connections is a defining characteristic of this flange style.

Flanges usually have a through hole and a square cut end (rather than the typical weld neck bevel). Generally, the bore diameter of the long weld neck is exactly the same as the actual nominal pipe size, but can be changed as needed. The overall length of the nozzle flange is also up to the end user, and the nozzle body can be modified to some pre-existing dimensions or custom sizes for additional reinforcement.

The base of the neck connecting to the base of the flange is slightly rounded to alleviate the sudden vertical connection between the two parts of the flange and reinforce the idea of strengthening the one-piece structure.

Butt weld flange, also known as tapered hub flange or high hub flange, is a flange that transfers stress to the pipe, ensuring that high stress concentrations at the bottom of the flange are reduced. There are two butt weld flange designs – the first is for rags, while the second, longer type cannot be used for pipes, but for processing plants.
