Why choose stainless steel 316 flanges?
Stainless steel 316 flange has high strength, durability, corrosion resistance and ability to resist immense pressure.
Corrosion resistance: It is highly resistant to corrosion as compare to other metals. As liquid and gas flow in oil pipeline cause internal corrosion in piping system.
Strength: Weld fitting and joint is generally a weak point for any of liquid and gas flow tool. Addition of molybdenum and titanium increase the strength and decrease the chance for deformation.
Versatility: It can be used for several of environment as it is appropriate for wide range of application both in indoor and outdoor.
Pressure and temperature tolerance: It resist high pressure and temperature. ASTM A182 F316 flange can be used in extreme temperature in range of 500 - 800°C.
Value: It is highly durable and can last for decade utilizing in liquid and gas flow with the piping system. It is easy to maintain and due to its corrosion resistance properties it doesn’t need to be replace for years.
What are the standards for SA 182 Gr F316 flanges?
The below given standards often applied to stainless steel flange which includes the following
How are 316 SS flanges made?
316 SS flange are made by using three main process such as casting, cutting rolled plate & forging. The main flange production consists processing of raw material than falling it in appropriate specification.
Raw material: It undergoes to a careful testing and approval process before purchasing it. The Mill Test Report reveals the chemical and physical properties which help to verify that the material meet the minimum requirement of your desired application.
Casting: It begins with molten metal which is poured into mold to form the desired shape of flange. After the liquid metal get hardened then the mold is opened and casting is been removed then it is machined to the required dimensions and surface finish.
Cutting: The process begin by flattening stainless steel stock by using rollers in order to thin the material until it gain desired plate thickness. Then it is cut to suitable outer and inner diameter using a laser, torch or water jet. Bolt holes and required grinder are cut and then the flange is further machined in exact specification.

Which SUS 316 flange connection is the strongest?
SUS 316 Weld neck flange provides the strongest connection as it gives the highest level of joint strength as it is butt-welded to the pipe.
Which type of material is used for making flange?
The typical material which is use for making the flange are given below:
What is the allowable gap between flanges?
The minimum suggested gap between the outermost border of two flanges are 25mm.
What is the purpose of 316 Stainless Steel Pipe Flanges?
The purpose of 316 Stainless Steel Pipe Flanges is to connect pipe with valve, fitting and specified element such as strainer and pressure vessel.
What are the 3 most common flange types?
The three most common type of flange are given below:
Welding Neck Flange
It is well-known for its long tapered hub which offer mechanical strength. It is available in various size with common face type. And due to its high strength and weldability it is suitable for high temperature and pressure application.
Slip-on flange
It is usually used to connect pipe by one or two fillet welds. However it is used only with a single weld. It can be manufacture in various sizes and it is recommended to be used in lower pressure applications.
Socket weld flange
It has socket in which a pipe is inserted and the pipe is secured by one fillet weld placed on the exterior of the flange hub. It is not considered for high strength weldability because the weld is difficult to prove, hence it is only suitable for low medium classes. Due to its lower strength and unsuitability to be used in higher pressure, it always has flat or raised face.
