Descrizione del prodotto
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

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.
