Black pipe is plain steel pipe without any protective coatings. Black pipe is used for a variety of applications around the home. It is very common to see black pipe used for your natural gas line and sprinkler system lines. Since black pipe has no protective coating, it may rust easily in wet or humid environments. To stop the pipe from rustin...

An iron-based mixture is considered to be an alloy steel when manganese is greater than 1.65%, silicon over 0.5%, copper above 0.6%, or other minimum quantities of alloying elements such as chromium, nickel, molybdenum, or tungsten are present. An enormous variety of distinct properties can be created for the steel by substituting these element...

A process for further refinement of stainless steel through reduction of carbon contentThe amount of carbon in stainless steel must be lower than that in carbon steel or lower alloy steel (i.e., steel with alloying element content below 5%). While electric arc furnaces (EAF) are the conventional means of melting and refining stainless steel, AO...

The corrosion of structural steel is an electrochemical process that requires the simultaneous presence of moisture and oxygen. In the absence of either, corrosion does not occur. Essentially, the iron in the steel is oxidised to produce rust, which occupies approximately 6 times the volume of the original material consumed in the process. The ...

1. Welded square tubes can be welded in a conventional manner, 45 degrees requires one lap weld, one fillet weld and two plane welds.2. No preparation is required prior to the fillet and lap weld positions, only the removal of rust, dirt or debris from the weld area.3. Before performing two plane welds, the metal n...

Yes，I Can.Galvanised steel pipes are very weldable and 2 galvanised pipes can be brought in for welding.

Welded joints are generally stronger than other jointing methods. In situations where lateral forces are present, such as tidal currents or wave actions, threaded joints may be weaker. It is best to use 'continuously welded' pipe.

(1) By process - arc welded pipe, resistance welded pipe (high frequency, low frequency), gas welded pipe, furnace welded pipe. (2) According to the weld seam - straight seam welded pipe, spiral seam welded pipe.

The most essential difference between seamless steel pipe and welded steel pipe is the weld seam . The body of seamless pipe has no weld seam, and the body of welded pipe is usually welded.

A steel pipe made by rolling steel coils/plates into a desired shape and welding them together, leaving seams in the body of the pipe during the manufacturing process, which can be cut to any length.

The thermal hardness of carbon steel pipes decreases significantly when the working temperature exceeds 200 degrees, leading to poor wear resistance. Additionally, carbon steel pipes have low hardenability.

However, it is more expensive than mild steel. Carbon steel is stronger than mild steel, making it a great choice for high-strength applications or where high hardness is required.

To calculate the weight of a steel tube, use the following formula: weight = π × [(diameter/2)² - (diameter/2 - thickness)²] × length × steel density. The density of steel varies according to the type: 7.88 g/cm³ for mild steel, 7.84 g/cm³ for carbon steel or 8.03 g/cm³ for stainless steel. ...

The most common method of connecting carbon steel pipes is through welded connections. These connections can be made using various methods, including electric welding, gas welding, and submerged arc welding. Manual arc welding and gas shielded welding are commonly used in electric welding. ...

There are many ways to cut carbon steel pipes, including sawing, cutting with knives, and so on. Please refer to this article for details:https://..........com/blog/How-to-cut-steel-pipe_b132

Hot-rolled steel pipes have an outer diameter ranging from 32mm to 630mm and a wall thickness of 2.5mm to 75mm. Cold-drawn steel pipes, on the other hand, have an outer diameter ranging from 5mm to 200mm and a wall thickness of 2.5mm to 12mm.

A500 Steel Pipe Grade B and Grade C are used for general structural purposes, such as columns, beams, and other load-bearing applications. Grade B has a minimum yield strength of 46,000 psi (315 MPa) and a minimum tensile strength of 58,000 psi (400 MPa).

The A500 grade specification covers carbon steel pipes used for structural purposes. These pipes are available in four grades: A, B, C, and D, each with different yield and tensile strengths. Grades B and C are the most commonly used for structural purposes.

ASTM A500 structural tubing is flat-rolled, roll-formed, welded by electric resistance welding.
