The flange is second most used joining method after selding. Flanges are used when joints need dismantling. It provides flexibility for maintenance. Flange connects the pipe with various equipment and valves. Breakup flanges are added in the pipeline system if regular maintenance in required during plant operation.
A flanged joint is composed of three separate and independent although interrdlated components; the flanges, the gaskets, and the bolting; which are assembled by yet another influence, the fitter. Special controls are required in the selection and application of all there elements to attain a joint, which has acceptable leak tightness.
A flange is a protruded ridge, lip or rim, either external or internal, that serves to increase strength (as the flange of an iron beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its parts (as the inside flange of a rail car or tram wheel, which keep the wheels from running off the rails). The term “flange” is also used for a kind of tool used to form flanges.

A stainless steel butt weld cap is a type of pipe fitting that covers the end of a pipe. Since it can have female threads, it can screw on to the male end of the pipe. It can also be welded on to close the end of the pipe. On a weld, if it is a temporary close, or the contractor wants to add to the piping system in the future, he or she should allow additional pipe before closing so the pipe cap can be cut off and the pipe system extended as needed. This way you will not have less pipe than you need and the new fitting can be attached correctly.
A Stainless Steel Butt Weld Cap is used to seal the end of a pipe or a particular butt weld fitting branch or orifice. Typically butt weld pipe caps are used at the end of a piping system or if maintenance is required the pipe cap can blind or isolate the rest of the system to keep it running while maintenance or repairs are performed.

Steel flanges provide an easy access for cleaning, inspection or modification. They usually come in round shapes but they can also come in square and rectangular forms. The flanges are joined to each other by bolting and joined to the piping system by welding or threading and are designed to the specific pressure ratings; 150lb, 300lb, 400lb, 600lb, 900lb, 1500lb and 2500lb.

A flange can be a plate for covering or closing the end of a pipe. This is called a blind flange. Thus, flanges are considered to be internal components which are used to support mechanical parts.

Alloy 317L can be easily welded and processed by standard shop fabrication practices.?

Annealing is a heat treatment process mainly used to increase the ductility and reduce the hardness of the material. This change in hardness and ductility is the result of the reduction of dislocations in the crystal structure of the annealed material. Annealing is usually done after the material has undergone a hardening or cold working process to prevent its brittle failure or to make it easier to handle later.

The flange is second most used joining method after selding. Flanges are used when joints need dismantling. It provides flexibility for maintenance. Flange connects the pipe with various equipment and valves. Breakup flanges are added in the pipeline system if regular maintenance in required during plant operation.

304 covers the standard for wrought austenitic stainless steel pipe fittings for pressure piping applications. The material of pipe fittings shall include forgings, bars, plates or seamless or welded pipes. Forging or forming operations shall be performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining, or a combination of two or more of these operations. All accessories should be heat treated.

A butt weld pipe fitting is designed to be welded on site at its end(s) to connect pipe(s) together and allow change in direction or pipe diameter, or branching or ending.

This fitting then becomes part of a system for transporting fluids (oil, gas, steam, chemicals, …) in a safe and efficient manner, over short or long distances.

One of the advantages of stainless steel over 316 stainless steel is that it is biocleaner than aluminum and copper, with biocleanability comparable to glass. The cleanability, strength and corrosion resistance of stainless steel have prompted the use of stainless steel in pharmaceutical and food processing plants.

Stainless Steel 310 Flanges are made up of a stainless steel grade that has high amounts of nickel and chromium. It is a chromium nickel alloy with 24% chromium and 19% nickel in the composition. Navstar Steel is a leading manufacturer and supplier of the Stainless Steel 310 Flanges in different variations.

Grade 904L is less resistant to nitric acid than grades 304L and 310L, which are free of molybdenum. This steel grade needs to be solution treated following cold working, to achieve maximum stress corrosion cracking resistance under critical environments

Grade F22 is a low alloy steel grade with a chromium content between 2% and 2.5%. The content of chromium and molybdenum is twice that of F11 grade. However, due to the maximum content of all alloying elements up to 5%, it is classified as a low alloy steel grade. As a low alloy steel grade, ASTM A182 F22 flanges outperform carbon steel, especially in applications involving high temperatures.
