Carbon Steel Coding
The AISI and the SAE have designed a four digit code to assign to all carbon and alloy steels to show its standard wrought steel composition. In carbon steel grades the last two digits indicate the nominal carbon content.[......]
What is Carbon Steel?
Carbon steel is steel in which the main interstitial alloying constituent is carbon in the range of 0.12–2.0%. [......]
What is Stainless Steel
Stainless steel is the name of a high alloy steel used mainly for its anti-corrosion properties. [......]

MSS SP-97, Socket Welding, Threaded, and Buttwelding Ends
MSS SP-97 Standard Practice covers essential dimensions, finish, tolerances, testing, marking, material, and minimum strength requirements for 90 degree integrally reinforced forged branch outlet fittings of buttwelding, socket welding, and threaded types.[......]
What Is Butt-Welding?
Butt-welding is the process of joining two pieces of material together along a single edge in a single plane. This process can be used on many types of materials, though metal and thermoplastics are the most common. When two sheets of steel are laid side-by-side and joined together along a single joint, this is an example of butt-welding.[......]
UNS S32615
UNS S32615 is a high silicon containing austenitic stainless steel. It was developed by Sandvik exclusively for use in concentrated sulphuric acid. [......]

Types and Uses of steel pipes
Steel pipe is long, hollow tube that are used for a variety of purposes. They are produced by two distinct methods which result in either a welded or seamless pipe. In both methods, raw steel is first cast into a more workable starting form. [......]
PVC Pipe
PVC was discovered in the late 1800s when vinyl chloride (C2H3Cl) was exposed to sunlight. The properties of the substance were noted at the time, but PVC was not put into practical application until the 1920s.[......]
Pipe Materials
Pipe is made from many different materials depending upon the properties of the media that is being transported.[......]
Flanges
Link
Flanges are used to connect together pipes or to connect a pipe to a choke, tee, valve or other equipment. There are many different flange standards to be found worldwide.[......]
What is Galvanized Steel Pipe?
Galvanized steel pipe is a steel pipe that has been coated with zinc. This coating protects the steel from corrosion. It is most commonly used for outdoor construction like fences and handrails, or for some interior plumbing.[......]
Definition of Pipe elbow
An elbow is a pipe fitting installed between two lengths of pipe or tubing to allow a change of direction, usually a 90° or 45° angle, though 22.5° elbows are also made. The ends may be machined for butt welding, threaded (usually female), or socketed, etc. When the two ends differ in size, the fitting is called a reducing elbow or reducer elbow.[......]
Type of Butt Weld Pipe Fittings
Pipe Fittings are applied to connect two pipe ends together, to change direction or size of the pipes. There are many different types and shapes on the market.[......]
Pipe Fitting by Types
Pipe fittings are widely demanded for any piping and plumbing systems used in industrial and commercial applications.[......]
Types of flange gaskets
Materials for gaskets can be divided into three main categories as Non-Metallic types, Semi-Metallic types, Metallic types.[......]
Flange Face Surface Finish
The American National Standards Institute (ANSI) code for flanges and flanged fittings (ANSI B16.5) requires that the flange face has a specific roughness to ensure that this surface be compatible with the gasket and provide a high quality seal.[......]
Flange face
Different types of flange faces are used as the contact surfaces to seat the sealing gasket material. ASME B16.5 and B16.47 define various types of flange facings, including the raised face, the large male and female facings which have identical dimensions to provide a relatively large contact area.[......]
Measure the size of a flange
Place one end of a tape measure on the inside of the flange. The diameter is used to determine what size pipe a flange can be used with, so you must find this information by using the inside of the flange as opposed to the outside.[......]
Applications of flanges
Flanges are integral parts of many engineering and plumbing projects. In many applications, engineers need to find a way to close off a chamber or cylinder in a very secure fashion, usually because the substance inside must differ from the substance outside in composition or pressure. [......]
What is a spectacle blind flange?
A spectacle blind – also known as a figure-8 blind – is generally a piece of metal that is cut to fit between two pipe flanges and usually sandwiched between two gaskets. [......]
