Petroleum Pipeline Pipe and Water Gas Transmission Pipe: Different Characteristics and Applications

Pipelines are the backbone of today’s infrastructure for oil, water, and gas. Among such products, a petroleum pipeline pipe and a water gas transmission pipe are two kinds of the most common types. While both are pipeline systems, the have very different material requirements, performance criteria and application areas.

What Is a Petroleum Pipeline Pipe?

Petroleum pipeline pipe is mainly used for the crude oil transporting, refined oil products and natural gas also be used. They are known to travel over long distances and across terrains including deserts, mountains and offshore.

Key characteristics include:

High strength and pressure resistance

Excellent toughness at low temperatures

Strong resistance to corrosion and cracking

Compliance with international standards such as API 5L, ISO 3183

They are most commonly found in oil fields, transcontinental pipelines, off-shore platforms, and refinery tie-in lines.

What Is a Water Gas Transmission Pipe?

Water gas transmission pipes are applied to convey drinking water, industrial water, natural gas, coal gas and so on for low-medium pressure fluid. They are commonly used in cities infrastructure and factories.

Main features include:

Moderate strength requirements compared with oil pipelines

Focus on safety, sealing performance, and corrosion resistance

Common standards include ASTM, EN, and local municipal standards

Often treated with coating, lining, or galvanizing

These pipes are the best choice for city water supply and city gas distribute system, industrial flow transportation, and farmland irrigation.

Key Differences Between the Two

Aspect Petroleum Pipeline Pipe Water Gas Transmission Pipe
Transported Medium Crude oil, refined oil, gas Water, natural gas, coal gas
Pressure Level High pressure, long-distance Low to medium pressure
Material Requirement High strength, high toughness Balanced strength and corrosion resistance
Common Standards API 5L, ISO 3183 ASTM, EN, local standards
Application Oil fields, cross-country pipelines, offshore Urban water and gas networks

Application Scenarios

Petroleum pipeline pipes are mostly used in big energy projects like oil and gas fields, long-distance main pipelines and offshore platforms. These projects need rigorous quality assurance and high-performance steel pipes to be safe in the operation for several decades.

Water gas transmission pipes are more concentrated in city and industry areas. They enable both life and work, and are at the heart of public utilities, factories, homes.
