ASTM Standard for Pipes, Fittings and Flanges
ASTM standards define the specific manufacturing process of the material and determine the exact chemical composition of pipes, fittings and flanges, through percentages of the permitted quantities of carbon, magnesium, nickel, etc., and are indicated by “Grade”. For example, a carbon steel pipe can be identified with Grade A or B, a stainless-steel pipe with […]
Types, Lengths and Ends of Pipes
Pipe manufacturing refers to how the individual pieces of pipe are made in a pipe mill; it does not refer to how the pieces are connected in the field to form a continuous pipeline. Each piece of pipe produced by a pipe mill is called a joint or a length (regardless of its measured length). […]
What is the difference between Pipe and Tube?
People use the words pipe and tube interchangeably, and they think that both are the same. However, there are significant differences between pipe and tube. The short answer is: A PIPE is a round tubular to distribute fluids and gases, designated by a nominal pipe size (NPS or DN) that represents a rough indication of […]
Counterfeit Steel is a Big Worry in the Industry
Counterfeit alert! Counterfeit products are fakes or unauthorized replicas of the real product. They are often produced with the intent to take advantage of the superior value of the imitated product. According to the Steel Alliance Against Counterfeiting (SAAC), more than 53% of the steel industry has personally come across fake products during their day-to-day […]
Seamless Stainless steel Pipe Carbonsteel Low-alloy Steel Cutting Plan
CUTTING PLAN The Pipe cutting plan shall be prepared for individual AFC piping isometric drawings by the piping engineer. Wherever field-welded joints are shown in the piping isometric drawings, a minimum of 200 mm extra length needs to be considered while making the cutting plan. Cutting and beveling of pipes may be done by flame […]
Alloy Steel versus Carbon Steel: the differences
There are about 36 million different kinds of steel grades in the world. However, it is hard to categorize each and one of them. Therefore, in this article, we will introduce two main types of steel: Alloy steel and carbon steel. Carbon steel is iron with carbon added (including a trace of other elements), while […]
Stainless steel is everywhere
Stainless steel has long been around. Since the 1990s, many sectors have been using stainless steel to build skyscrapers, monuments, and even kitchen utensils. You are likely to be surrounded by artifacts of stainless steel such as saucepans, handrails, pen springs, or watches. And if you use shipping containers, exhaust systems, cable trays, or process […]
Difference between 304 and 316 stainless steel
304 Stainless Steel and 316 Stainless Steel are often compared since they cannot be distinguished by their looks but by their properties. In addition, they both are widely used in everyday life tools. However, they do have distinct differences that need to be considered before choosing one another. The 304 stainless steel SAE 304 stainless […]
What are the Main Olet Fittings?
What are the Main Olet Fittings? Olet Fittings (also called Branch Connection Fittings or Outlet Fittings) are fittings which provide an outlet from a larger pipe to a smaller one (or one of the same size). The main pipe onto which the branch connection is welded is usually called the Run or Header size. The […]
What are the Main Types of Flanges?
What are the Main Types of Flanges? We usually consider two main families of flanges, the standard flanges and the special ones. What is a steel flange? “A flange is a forged or cast ring of steel designed to connect mechanically sections of pipe or join pipe to a pressure vessel, pump, valve or […]
