Steel Pipes for Specialized Applications

 Steel Pipes for Specialized Applications

 

1.Pipes for Oceanographic Engineering and Submarine Pipelines 

Purpose: Used in underwater environments for transporting oil, gas, or water. These pipes must withstand high pressure, corrosion from seawater, and extreme conditions. 

Characteristics: Typically seamless or welded steel pipes with anti-corrosive coatings (e.g., epoxy or polyethylene) and high-strength alloys. 

Standards: API 5L, DNV-OS-F101. 

Applications: Offshore oil/gas pipelines, underwater infrastructure.

2.Steel Pipe for Power Station Boiler 

Purpose: Used in high-temperature, high-pressure environments within power plant boilers to carry steam or hot water. 

Characteristics: Made from heat-resistant alloys or carbon steel, seamless to prevent leaks, with excellent thermal conductivity. 

Standards: ASTM A192, ASME SA-210. 

Applications: Thermal power plants, industrial boilers.

3.Steel Pipe for Petroleum, Chemical Engineering, and Chemical Fertilizer 

Purpose: Designed for transporting corrosive fluids or gases in refineries, chemical plants, and fertilizer production. 

Characteristics: Corrosion-resistant, often stainless or alloy steel, seamless or welded depending on pressure requirements. 

Standards: ASTM A106, API 5L. 

Applications: Petrochemical processing, ammonia/urea production.

4.Steel Pipe for Engineering and Mechanical Purposes 

Purpose: General-purpose pipes for structural or mechanical applications, such as machinery, construction, or equipment manufacturing. 

Characteristics: High strength, good machinability, often carbon or low-alloy steel, seamless or welded. 

Standards: ASTM A519, EN 10297. 

Applications: Cranes, automotive parts, structural frameworks.

5.Steel Pipe for Gas Cylinder 

Purpose: Used to manufacture high-pressure gas cylinders for storing gases like oxygen, nitrogen, or CNG. 

Characteristics: Seamless, high-strength steel with precise wall thickness to ensure safety under pressure. 

Standards: ISO 9809, DOT-3AA. 

Applications: Industrial gas storage, medical oxygen cylinders.

6.OCTG (Oil Country Tubular Goods) 

Purpose: Specialized pipes for oil and gas exploration and production, including casing, tubing, and drill pipes. 

Characteristics: High strength, seamless or welded, designed for harsh downhole conditions, often with threaded connections. 

Standards: API 5CT, API 5DP. 

Applications: Oil/gas wells, drilling operations.

7.Seamless Steel Pipe for Ships 

Purpose: Used in shipbuilding for piping systems carrying fuel, water, or steam. 

Characteristics: Seamless for reliability, corrosion-resistant to withstand marine environments. 

Standards: ABS, LR, DNV-GL rules. 

Applications: Ship engines, cooling systems, ballast lines.

O.D.: 19MM-1219MM

W.T.: 2MM-150MM
