EN 10216-2 P235GH Pressure Purpose Seamless Steel Tube For Boilers And Heat Exchangers
EN 10216-2 P235GH Seamless Steel Tube is a non-alloy pressure-purpose steel tube manufactured in accordance with the European standard EN 10216-2. Designed for elevated-temperature service, P235GH tubes are widely used in boilers, heat exchangers, pressure vessels, pipelines, and industrial heating systems where reliable mechanical strength and good weldability are required.
Industrial Challenges
Many industrial projects require pipelines that can withstand high pressure, corrosion, temperature fluctuations, and long-distance transportation requirements. Traditional piping solutions often face challenges such as:
High material costs for large-diameter pipes
Limited availability of seamless pipes in large sizes
Difficult installation in long-distance pipeline projects
Corrosion risks in underground and offshore environments
Reduced efficiency due to leakage and mechanical failures
Solution
SSAW Spiral Welded Steel Pipes provide an ideal solution by combining high structural strength with cost-efficient manufacturing. Key advantages include:
Large diameter production capability
Excellent weld integrity through submerged arc welding
High pressure-bearing performance
Suitable for oil, gas, water, slurry, and chemical transportation
Multiple anti-corrosion coating options including FBE and 3PE
Lower production costs compared with large-diameter seamless pipes
Long service life in demanding environments
These benefits make SSAW steel pipes one of the most widely used pipeline products worldwide.

How It Works
SSAW pipes are manufactured by continuously forming hot-rolled steel coils into a spiral shape and welding the seam using submerged arc welding technology. The process includes:
Steel coil preparation
Spiral forming
Inside submerged arc welding
Outside submerged arc welding
Hydrostatic pressure testing
Surface coating and inspection
The spiral weld design distributes internal pressure evenly throughout the pipe wall, providing excellent mechanical strength and durability. For corrosion protection, coatings such as FBE (Fusion Bonded Epoxy) and 3PE (Three-Layer Polyethylene) can be applied to extend service life in harsh environments.
How To Choose
When selecting SSAW steel pipes, consider the following factors:
Medium Being Transported
Water → Standard coated SSAW pipe
Oil → API 5L pipe with anti-corrosion coating
Natural Gas → API 5L X52/X60/X65 grades
Chemicals → FBE or 3PE coated pipe
Operating Pressure
Higher pressure systems require thicker wall pipes and higher-grade materials.
Corrosion Environment
Underground and offshore applications should use FBE or 3PE external coatings.
Pipe Diameter
Choose diameter according to flow rate requirements and project design specifications.
Standard Requirement
API 5L for oil and gas pipelines
ASTM A252 for piling applications
EN standards for European projects
Product Applications
Oil and Gas Transportation
Used for crude oil, natural gas, and refined petroleum transmission pipelines.
Water Supply Projects
Suitable for municipal water supply systems, irrigation projects, and water transmission networks.
Structural Construction
Applied in bridges, buildings, foundations, piling, and steel structures.
Chemical Industry
Used for conveying chemicals, industrial fluids, and process materials.
Energy and Power Plants
Widely utilized in thermal power stations and industrial utility systems.
Offshore and Pipeline Engineering
Suitable for long-distance transmission pipelines and marine infrastructure projects.

Frequently Asked Questions
Q1: What is the difference between SSAW and seamless steel pipe?
SSAW pipes are manufactured by spiral welding steel coils, while seamless pipes are produced without a weld seam. SSAW pipes are more economical for large diameters and long-distance pipeline projects.
Q2: Can SSAW pipes be used for natural gas transmission?
Yes. API 5L grades such as X52, X60, and X65 are widely used in natural gas transportation systems worldwide.
Q3: What anti-corrosion coatings are available?
Common options include Black Paint, Anti-Rust Oil, Fusion Bonded Epoxy (FBE), and Three-Layer Polyethylene (3PE) coatings.
Q4: Are customized sizes available?
Yes. Customized diameter, wall thickness, length, coating, and end preparation can be manufactured according to project requirements.
Q5: What inspections are performed before shipment?
Each pipe can undergo hydrostatic testing, dimensional inspection, ultrasonic testing (UT), and visual quality checks to ensure compliance with international standards.
