In general, we do not recommend burying black natural gas steel pipes unless the surface of the pipe is covered with an antioxidant protective coating or hot-dip galvanized treatment. The moisture-proof and durable properties of the steel pipe will be greatly improved. After adding coating protection, the pipe can ...

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.

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.

Manufacturing Process: Seamless pipes are formed by drawing a solid billet over a piercing rod to create a hollow tube, while ERW (Electric Resistance Welded) pipes are made by rolling a steel coil and welding the edges together under high pressure.Strength and Durability: Seamless pipes are considered to be strong...

Introduction When it comes to selecting the right type of steel pipe for various applications, two popular options are b...

The answer is yes. In fact, some manufacturers have introduced precision seamless steel pipes in domestic water pipelines and added rust prevention treatment to improve the applicability of steel pipes in domestic water. Although they are sometime...

Today, the editor will bring you the theoretical weight table of carbon steel pipes and the formula for calculating the theoretical weight of carbon steel pipes. Let's take a look together! 1. Formula: kg/m=(Od Wt) * Wt * 0.02466=28 * 0.8 * 2600=1...

ERW steel pipe "is a straight seam resistance welding pipe, abbreviated as ERW in English. It is used to transport vapor-liquid objects such as oil and natural gas, and can meet various requirements of high and low pressure. It plays a pivotal role in the field of transportation pipes in the world. It is also one o...

Square steel pipes offer several advantages over other types of pipes, such as easier installation, superior strength and durability, high resistance to corrosion, and cost-effectiveness. They are also suitable for transporting fluids and gases, as well as providing structural support. ...

A square steel pipe is a type of hollow structural section that is made from steel. It has a square-shaped cross-section and is commonly used in various applications, including construction, automotive, and manufacturing industries.
