When choosing steel pipes suitable for water transportation, we do need to carefully consider multiple factors. The following is a more detailed analysis of several common types of steel pipes:

Galvanized steel pipe

Material and process: Galvanized steel pipe is coated with a layer of zinc on the surface of the steel pipe to enhance its corrosion resistance. Mainly divided into hot-dip galvanizing and electroplating galvanizing, hot-dip galvanizing has a thick coating, strong adhesion, long service life, but the surface is not smooth; Electrogalvanizing has a thinner coating and a smoother surface, but its corrosion resistance is slightly inferior to hot-dip galvanizing.

Performance characteristics: Galvanized steel pipes not only have excellent corrosion resistance, but also have certain wear resistance, which can resist mechanical wear to a certain extent. At the same time, its strength and load-bearing capacity are also high, suitable for various situations that require bearing certain pressure or weight.

Applicable scenarios: Galvanized steel pipes are widely used in building structures, plumbing systems, industrial applications, as well as horticulture and agriculture. Galvanized pipes are often used as water supply and drainage pipes in household and commercial plumbing systems, and their durability and rust resistance help extend the lifespan of the system.

Seamless steel tube

Material and Craftsmanship: Seamless steel pipes are made by piercing a whole round steel without any weld seams on the surface. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold drawn seamless steel pipes, extruded seamless steel pipes, etc.

Performance characteristics: Seamless steel pipes have a hollow cross-section and are widely used as pipelines for transporting fluids, such as oil, natural gas, coal gas, water, and certain solid materials. Compared with solid steel such as round steel, seamless steel pipes are lighter in weight when their bending and torsional strength is the same, making them an economical cross-sectional steel. Meanwhile, seamless steel pipes also have high strength and load-bearing capacity, making them suitable for harsh environments such as high pressure and high temperature.

Applicable scenarios: Seamless steel pipes are mainly used as drilling pipes for petroleum geology, cracking pipes for petrochemicals, boiler pipes, bearing pipes, as well as high-precision structural steel pipes for automobiles, tractors, and aviation. Seamless steel pipes are widely used in fields such as water conservancy engineering and urban water supply due to their excellent performance.

Welded steel pipe

Material and process: Welded steel pipes are carbon steel pipes formed by bending steel strips or plates and welding them into circular or square shapes. According to different welding methods, welded steel pipes can be divided into resistance welded steel pipes (ERW), spiral welded steel pipes, etc.

Performance characteristics: Welded steel pipes have the advantages of high material utilization, simplified manufacturing process, and saving steel and processing time. At the same time, welded steel pipes have high precision, uniform wall thickness, and high internal and external surface brightness. In addition, welded steel pipes also have characteristics such as corrosion resistance, acid resistance, alkali resistance, salt resistance, and atmospheric corrosion resistance.

Applicable scenarios: Welded steel pipes are widely used in compressor stations, power plants, refineries, and natural gas transmission fields. Welded steel pipes are widely used in the water supply pipelines of civil buildings due to their low price and ease of processing. However, it should be noted that the welding quality of welded steel pipes needs to be strictly controlled to ensure their overall performance.

Other types of steel pipes

Alloy steel pipe: Alloy steel pipe is a type of pipe made of high-quality carbon steel, alloy structural steel, and stainless heat-resistant steel. Alloy steel pipes have the advantages of high strength, good corrosion resistance, and high temperature resistance, and are suitable for transporting chemical substances, marine engineering, oil and gas, and other fields. But the price of alloy steel pipes is relatively high, and there are special welding process requirements.

Cast iron pipe: Cast iron pipe is a pipe formed by casting cast iron, including cast iron straight pipes and fittings. Cast iron pipes have the advantages of high strength, good toughness, thin pipe wall, and low metal consumption. Especially ductile iron pipes, which have the essence of iron, the properties of steel, and excellent corrosion resistance and ductility, are the preferred pipe materials for municipal, industrial and mining enterprises in water supply, gas transmission and other occasions. But the weight of cast iron pipes is relatively large, and the construction difficulty is also relatively high.

In summary, when selecting steel pipes suitable for water transportation, comprehensive consideration should be given to specific engineering requirements, usage environment, budget, and other factors. Galvanized steel pipes are suitable for water supply pipelines in general residential and commercial buildings due to their excellent anti-corrosion performance and moderate price; Seamless steel pipes are suitable for water supply pipelines in harsh environments such as high pressure and high temperature due to their high strength and excellent corrosion resistance; Welded steel pipes are suitable for water supply pipelines in general civil buildings due to their low price and ease of processing; Alloy steel pipes and cast iron pipes are suitable for water supply systems in specific situations.

Among the many types of steel pipes, ordinary carbon steel pipes and galvanized steel pipes are the two most commonly used. The following is a detailed analysis of these two types of steel pipes:

Ordinary carbon steel pipe

Characteristics: Ordinary carbon steel pipe is one of the most common steel pipes, with moderate strength and good processing performance. It is easy to weld and shape, and can meet various processing needs.

Application: Due to its wide applicability, ordinary carbon steel pipes are widely used in various industries such as construction, machinery, automobiles, petrochemicals, etc. In the field of architecture, it is often used as a structural support and a pipeline for transporting fluids; In mechanical and automotive manufacturing, it is used to manufacture various components.

Galvanized steel pipe

Characteristics: Galvanized steel pipes are coated with a layer of zinc on the surface of ordinary carbon steel pipes to improve their corrosion resistance and service life. This type of steel pipe has good durability and protective performance, which can effectively prevent corrosion and rusting.

Usage: Galvanized steel pipes are widely used in multiple fields due to their excellent anti-corrosion performance. In the field of architecture, it is often used as indoor water supply pipes, drainage pipes, and piping for HVAC systems; In hydraulic engineering, it is used to transport water and other fluids; In the fields of highway bridges and culverts, it is used to construct structures such as guardrails and road signs.

In addition, although seamless steel pipes, alloy steel pipes, welded steel pipes, etc. are widely used in other specific fields, ordinary carbon steel pipes and galvanized steel pipes are used in a wider range, especially in industries such as construction, machinery, automobiles, and petrochemicals.

In summary, ordinary carbon steel pipes and galvanized steel pipes have become the most commonly used types of steel pipes due to their respective characteristics and wide applicability. When selecting steel pipes, it is necessary to choose according to specific application scenarios and requirements.
