HT PIPE is one of the leading Stainless Steel 304 Flanges China Manufacturer, Exporter, Supplier using Nickel to maintain austenite synthesis at low temperature. Hardened steel 304 slip flange is an austenitic treated steel that provides better corrosion resistance than tempered steel 317.

These threaded flanges are suitable for welding as they have a carbon content lower than the 301 to 303 permutation, which avoids carbide precipitation in welding applications. Stainless steel butt weld flanges are often used for gears in composite, nutritional, paper, mining, pharmaceutical and petroleum companies. The expansion of molybdenum and the slightly higher nickel content make stainless steel 304 blind flanges suitable for structural applications in harsh environments, from dirty marine environments to sub-zero temperatures.

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.

Stainless steel 304 flanges are components used to join pipes together. They differ from fittings in that all flanges have an outward protrusion that provides additional space for connections such as welding or bolting.

SS 304 flange is a special type with orifice and ANSI B16.5 SS 304 blind flange is another special type which does not connect wires but terminates wires.

Our UNS S30400 Stainless Steel Butt Weld Flanges are available in a variety of schedules, are able to accommodate the inside diameter of the pipe, and are easily identifiable due to their sporting tapered hub.

There are stainless steel 304 slip flanges that allow the pipe to slide over the flange for better positioning of the connection. Sometimes soldering may not be an option. For this case, use ASTM A182 SS F304 threaded flanges. ASTM A182 is a specification for wrought and rolled alloy steel flanges.

304 stainless steel flanges are considered the most basic stainless steel, also known as grade 18-8, with higher chromium content and lower carbon content. The presence of low carbon content in the alloy limits the formation of carbide deposits during welding while minimizing the susceptibility of 304 stainless steel flanges to intergranular corrosion.

Stainless steel 304 flanges are suitable for high temperature service. SS Werkstoff No 1.4301 Socket Weld Flanges have sockets welded on them for more connections and Stainless Steel 304 RTJ flanges have ring joints for easy connection.

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.

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. Flanges are usually welded or threaded. Flange joints are made by bolting two flanges together with a gasket between them to provide a seal.

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.

HT PIPE is one of the leading suppliers and traders of SS 304 flanges which are nickel plated to maintain austenitic composition at lower temperatures. Stainless Steel 304 Slip Flanges are austenitic stainless steel with better corrosion resistance than Stainless Steel 317.

These stainless steel 304 threaded flanges are suitable for welding as it has a lower carbon content than 301 to 303 series alloys to avoid carbide precipitation in welding applications. Equipment in the chemical, food, paper, mining, pharmaceutical and petroleum industries often includes stainless steel 304 butt weld flanges. The addition of molybdenum and a slightly higher nickel content make stainless steel 304 blind flanges suitable for construction applications in harsh environments, from contaminated Marine environment to areas with temperatures below zero.

Stainless Steel UNS S30400 Socket Weld Flanges also offer higher creep, rupture stress and tensile strength at elevated temperatures, excellent corrosion resistance and strength properties, making them ideal for manufacturing or forming applications.

Stainless steel 304 lap flanges are ideal for applications that require better corrosion resistance than Type 316 with good high temperature strength. The stainless steel 304 ring joint style flange is a low carbon version and is immune to sensitization. Therefore, stainless steel 304 eyeglass blind flanges are very frequently used for heavy duty welded components. Stainless steel 304 Nippolet flanges are considered resistant to pitting corrosion in chloride drinking water at ambient temperature, degrading at 60 degrees Celsius.

Stainless steel 304 flanges are widely used in petrochemical, oil and gas, power generation, bulk liquid transportation, chemical, pharmaceutical, pulp and paper, textile and other industries.

All our SS 304 flanges are manufactured to international standards. Stainless steel 304 pipe flanges are packaged to ensure no damage during shipping. In case of export, standard export packing is done in wooden case. All stainless steel 304 plate flanges are marked with grade, lot number, size, degree and our trademark.

Stainless steel 304 flanges are made from the 18/8 chrome-nickel austenitic stainless steel alloy most used in stainless steel applications.

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.

These flange styles are also known as “Straight Hub Weld Flanges” according to ASME B16.5 subsection 2.8 and are given minimal detail in the governing code. This is because long weld necks are selected on a per application basis according to the specific engineering requirements of a given tank or pressure vessel. The working pressure, temperature and medium of the vessel are all key factors in determining which type of long butt weld flange connection you need.

In addition to the standard long weld neck, Texas Flange offers a variety of nozzle connections with varying wall thicknesses. When your pressure vessel requires a stronger outlet connection and can provide your desired barrel thickness, a reinforced barrel flange in the form of a nozzle is an option. Please contact us for your specific application as we can supply nozzle flanges in all commercially available material grades including carbon, stainless steel and nickel alloys.

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.

A butt weld flange (WN) conforming to ASME B16.5 is a typical one-piece flange. It is integrally cast or forged with a tapered neck butt welded to the tube. This design provides a smooth transition with few stress concentrations, as high stress concentrations at the bottom of the flange are reduced by transferring stress to the adjacent piping.

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.
