GI stands for "galvanized iron". Thus, GI pipes are galvanized iron pipes, or called coated iron pipes in old terminology. GI carbon steel pipes are immersed in a galvanic (zinc) bath. GI (Galvanized Iron) Pipes are classified into 3 grades based on their weight per meter and inner diameter thickness. The more thickness, the better the performance, and durability. According to IS 1239, each pipe shall bear a color strip across the circumference for identifying the "class" of the GI pipes. These pipes are cheaper, lightweight, and easy to handle.
Difference between GI and GP pipes
The full Form of GP pipe is "Galvanized Pipe". GP Pipes are made of thin sheets of carbon steel electroplated with zinc and then rolled into pipes. GP pipes are superior to GI pipes in terms of finish. Galvanized pipes are dipped in a protective zinc coating to prevent corrosion and rust. This piping was commonly installed in homes built before 1960. When the galvanized pipe was invented, it became an alternative to lead pipe for water supply lines.
Galvanized pipe and tube, covered with zinc, increases the pipes and tubes life expectancy and make them more resistant to corrosion and mineral deposits in the line. It is a plumbing material that is used in water supply lines and has been used in homes for years.
MS Pipes and Tubes
Square Tubes
MS stands for "Mild Steel." And so, MS Pipes are made from mild steel they can easily be welded and formed in various shapes and sizes for pipelining and tubing purposes. These are generally used for drinking water supply i.e. Plumbing, Firefighting, and HVAC but can also be used in various other Industrial and Engineering applications.
Mild steel pipe refers to the content of less than 0.25% carbon steel because of its low strength, low hardness, and softness. MS pipes or tubes contain a small amount of carbon (0.18% or less) steel.
Mild Steel Pipe and MS Tubes conforming to IS:1239 Part I (1/2" to 6" NB - A-Class, B Class OR C Class) large-diameter Mild Steel Pipes confirming to IS:3589 Grade FE 330 or GR FE 410 (up to 20″, 508mm as per required wall thickness.)
MS Steel Black Pipes and Tubes
Mild Steel Black Pipes are called MS Black Pipe because it is not galvanized and is an ideal product to be welded into pipes, tubes, and other kinds of tubing. It is one of the cheapest metals available in the market and can last up to 100 years if placed in a well-maintained environment.
Sparsteel produces high-quality laser-welded pipes and tubes from 0.19 mm to 152.4 mm diameter, and various other sizes of Round Tubes, Square Tubes, and Rectangular Tubes that can be used for any application requiring the greatest performance, durability, strength, and security.
PIPE AND TUBE MANUFACTURING PROCESS
Steel pipes are long and hollow tubes that are used to convey products like liquid, gas, etc. from one place to another. They are produced mainly by two distinct manufacturing methods which result in either a welded pipe or a seamless pipe. In both manufacturing methods, raw iron or steel is first cast into a more workable starting form (i.e. hot billet or flat strip). It is then made into a pipe by stretching the hot steel billet out into a seamless pipe or forcing the edges of a flat steel strip together and sealing them with a weld. In this heading, we will discuss the various methods involved in welded pipe manufacturing along with its history.
In the beginning, pipe, and tube were manufactured by hand - by heating, bending, lapping, and hammering the edges together. The historical evidence pointed out the first automated pipe manufacturing process was introduced in 1812 in Britain (England).
And manufacturing processes of Pipes and tubes have continually improved since 1812 with the invention of scientific methods, materials, and technology.
