Manufacturing Process	Billets and coils are delivered to the pipe mill ready to be made into carbon steel pipe. Depending on the capabilities of the pipe mill and the end use of the final product, the casts will be formed into pipe by means of four distinct different manufacturing.Seamless carbon steel pipe has, as its name implies, no longitudinal weld seam. It is, in essence, one solid homogeneous piece of steel. A solid billet is simply heated and then stretched over a series of mandrels until the pipe has achieved its desired diameter and wall thickness.

Steel Seamless Pipe Introduction

 

Seamless Carbon Steel Pipe:What is seamless definition? or seamless meaning? we get this question a lot. Seamless pipe is produced in sizes from 1/8 to 36"nominal. Seamless pipe has no longitudinal seam or weld when compared to ERW pipe. In simple terms the seamless pipe is produced by piercing a solid round billet leaving behind a hollow seamless pipe. There are two main methods of producing seamless pipe;
1. Hot Rotary Piercing
2. Extrusion Process Method

In Extrusion Process, hot billets of metal are formed into seamless pipe by forcing the billets through extrusion dies and over a forming mandrel.

Hot rotary piercing method is the most common process of producing seamless pipe. In this process hot billets are forced through rotating heavy rollers over a mandrel or piercing plug. The piercing plug creates the hole through the seamless cylindrical billets. Picture below illustrates the hot rotary process.

Seamless pipe goes through various finishing operations such as straightening, inspection, hydro testing and imaging. Seamless pipe is widely used in pressure piping, construction, petrochemical and oil refineries. Seamless pipe is available in the following specifications;ASTM A53, A106, A252, A333, A335, A501, A523, A589, API 5L and API 5CT. Most common seamless pipe is A106B.End finish of seam less pipe includes plain ends either beveled or square cut. Seamless carbon steel pipe is available in black,bare, galvanized or with epoxy coating.

Steel Pipe Lengths:

Generally steel pipe is supplied in 21 ft lengths.It is also available in Single Random Length (SRL) which could be anywhere from 17 ft to 24 ft.Double Random Length (DRL) refers to pipes that is at least 37 ft long and up to 44 ft.
Steel Pipe End Finish:There are five common type of metal pipe end finishes;1. Threaded and Coupled2. Threaded without Coupling3. Plain End - Cut Square4. Beveled for Welding - 30 deg bevel5. Grooved End - Cut or rolled for mechanical coupling
Metal Pipe Finishing Processes:

Most common finish on the metal pipe is lacquer coating that prevents corrosion and protects the pipe from weather. This is also called Black Iron Pipe. Other than lacquer, there are four types of metal pipe finishes;1. Bare Metal2. Pickled only3. Pickled and Oiled4. Galvanized PipeGalvanizing involves using zinc coating as a sacrificial element to prevent corrosion. Zinc is usually applied by a hot dipping process where pipe is submerged in a molten bath of zinc solution. Standard weight of zinc is 1.8 oz per sq ft.Galvanized pipes provide good protection to the pipe inside and out.
Steel Pipe Coating and Lined Steel Pipe:Pipe's corrosion resistance can also be enhanced with corrosion resistant pipe coating.Such coatings are usually long lasting compared to lacquer or galvanized finishes.There are three main types of Corrosion Protective Coating for Steel Pipe.
Steel Pipe Material:

Metal Pipes are available in following material grades;A106B/A53B/API 5L-X42/API 5L BStainless Steel 304Stainless Steel 316Super Stainless A20Duplex Stainless D2205Nickel Alloy A200Nickel Alloy A400Nickel Alloy A600
Stainless Steel Pipe:

Stainless steel is iron based alloy containing a minimum of 16% chromium.Nickel is another important alloying element instainless steel pipe. Stainless Steel pipes are highly resistant to corrosive media and to oxidation at almost any temperature.

 

Stainless steel welded and seamless pipes are used for variety of reason such as to resist corrosion, preform at high temperature,for clean look and low maintenance cost. The most important aspect for stainless steel pipe is its inherent material characteristics that allows much thinner walls to be created such as sch 5, sch 10 without compromising the structural integrity of the pipe. The use of fusion welding to join pipe also eliminates the need for threading.

Type 304 stainless steel pipe is mostly used for general corrosive resistant application. it is used in chemical plants,refineries, paper mills and food industries. 304SS pipe has maximum carbon content of 0.08%. It is not recommended for use in the temperature range between 800 deg F and 1650 deg F due to carbide precipitation at the grain boundaries. Type 304L is the same as 304 except that it has a 0.035% maximum carbon content.

Type 316SS pipe is much more resistant to pitting than other chromium nickel alloys due to the addition of 2-3% molybdenum. It is useful in applications with acids, brines, sulphur water, sea water and with hologen salts. 316L stainless steel pipe, like 304L,has a max carbon content of 0.035%.

Welded Stainless Steel Pipe is made to specification ASTM A312 and A358. A312 is the most common spec for stainless steel pipe.Welded stainless pipe is made from 1/8" to 24" NPS.

Seamless Stainless Steel Pipe is made to specification ASTM A312 and A376. A312 is also the most common spec for seamless stainless steel pipe. Seamless stainless pipe is made from size 1/8 to 14" nominal.
