Seamless Alloy Steel Pipe and Tube

Product Type:
      Seamless Alloy Steel Pipe/Tube
 
Dimension:
       1/2" to 28",             21mm to 720mm
 
Wall Thickness:
        SCH5 to XXS,      5mm to 120mm
 
Standard:
        ASTM, ASME, API, EN, DIN, JIS, GOST etc.

Length:
       Piping lengths from the factory not exactly cut to length but are normally delivered as:
       - Single random length has a length of around 5-7 meter
       - Double random length has a length of around 11-13 meter
       - Shorter and longer lengths are available according to customer's require.

Material Features

Alloy Steel:

A steel, other than a stainless steel, that conforms to a specification that requires one or more of the following elements, by mass percent, to have a minimum content equal to or greater than: 0.30 for aluminum; 0.008 for boron; 0.30 for chromium; 0.30 for cobalt; 0.40 for copper; 0.40 for lead; 1.65 for manganese; 0.08 for molybdenum; 0.30 for nickel; 0.06 for niobium (columbium); 0.60 for silicon; 0.05 for titanium; 0.30 for tungsten (wolfram); 0.10 for vanadium; 0.05 for zirconium; or 0.10 for any other alloying element, except sulphur, phosphorus, carbon, and nitrogen.

Low-alloy Steels:

A steel, other than a carbon steel or an interstitial-free steel, that conforms to a specification that requires the minimum content for each specified alloying element to be lower than the applicable limit in the definition for alloy steel.
     As with steels in general, low-alloy steels can be classified according to:
      - Chemical composition, such as nickel steels, nickel-chromium steels, molybdenum steels, chromium-molybdenum steels
      - Heat treatment, such as quenched and tempered, normalized and tempered, annealed.

High-Strength Low-Alloy Steels: 

The HSLA steels have low carbon contents (0.05-0.25% C) in order to produce adequate formability and weldability, and they have manganese contents up to 2.0%. Small quantities of chromium, nickel, olybdenum, copper, nitrogen, vanadium, niobium, titanium and zirconium are used in various combinations.

Pipe & Tube Concept

Pipe is a hollow tube with round cross section for the conveyance of products. The products include fluids, gas, pellets, powders and more.  In the world of piping, the terms pipe and tube will be used. Pipe is customarily identified by "Nominal Pipe Size" (NPS), with wall thickness defined by "Schedule number" (SCH).

Tube is a cylindrical length of material that is usually hollow. Tubing can have a rectangular or square profile too.Tube is customarily specified by its outside diameter (O.D.) and wall thickness (WT).The principal uses for tube are in Heat Exchangers, instrument lines and small interconnections on equipment such as compressors, boilers etc..
