Featured Steel Pipe Products
Bitumen Coated Piling Steel Pipe 813mm OD 12.7mm WT for Corrosive Soil Protection
Engineered to provide an exceptionally robust and cost-effective foundation barrier in the most aggressive subterranean environments, this Bitumen Coated Piling Steel Pipe is optimized for corrosive soil protection. Utilizing a large 813mm nominal outer diameter (32-inch NPS) welded carbon steel base pipe and a standard half-inch (12.7mm) wall thickness, this structural steel pile delivers outstanding axial load capacity.
The exterior of the pipe is protected by a heavy-duty, thick bituminous layer applied in strict compliance with the BS 534 or AWWA C203 standards. This highly inert, water-impermeable asphalt barrier completely isolates the carbon steel substrate from acidic clays, saline groundwater, aggressive landfill leachates, and anaerobic soil bacteria, preventing corrosion-induced wall thinning and securing a 50+ year subterranean service life for critical public works and commercial foundations.
EN 10219 S355J2H LSAW Steel Pipe Pile 36 Inch 25.4mm WT for Offshore Wind Farm
Engineered to withstand the relentless cyclic wave actions and immense structural loads of offshore renewable energy installations, this EN 10219 S355J2H LSAW Steel Pipe Pile is optimized for offshore wind farm foundations. Utilizing a 36-inch nominal outer diameter (914.4mm OD) and an ultra-heavy wall thickness of 25.4mm (1.00 inch), this pile is manufactured using the Longitudinal Submerged Arc Welding (LSAW) process. This ensures precise dimensional tolerances, high roundness, and minimal residual stress.
Fully compliant with the strict European structural standard EN 10219, the high-strength S355J2H steel grade features a minimum yield strength of 345 MPa (for heavy wall thicknesses greater than 16mm) and guaranteed "J2" Charpy V-notch impact toughness at -20°C. This heavy-duty, straight-seam pile is designed to serve as critical jacket piles or structural pin piles, delivering exceptional fatigue resistance and structural safety against continuous dynamic wind turbine vibrations and deepwater subsea currents.
ASTM A500 Grade B Welded Piling Pipe 406mm OD with Conical Point for Soil Piling
Engineered to provide excellent ground consolidation and dependable end-bearing capacity, this ASTM A500 Grade B Welded Piling Pipe is optimized for high-performance soil piling. Utilizing a versatile 406mm outer diameter (16-inch equivalent) cold-formed welded steel host pipe, this structural pile is equipped with a heavy-duty pre-welded conical point at the pile tip.
The conical tip seals the pipe bottom, converting the assembly into a closed-end displacement pile that prevents mud, water, and debris from entering the tube during driving. Fully compliant with ASTM A500 Grade B structural standards, this pile offers a minimum yield strength of 290 MPa. It is designed to pierce through dense gravel and clay layers, compacting surrounding soils and transferring heavy vertical building loads directly to reliable bedrock or load-bearing strata.
Heavy Wall Thickness SSAW Piling Pipe 1220mm OD for Marine Port Construction
Engineered to withstand the extreme dynamic loads and aggressive corrosive environments of maritime infrastructure, this Heavy Wall Thickness SSAW Piling Pipe is the premier structural foundation for marine port construction. Utilizing a large 1220mm nominal outer diameter and a heavy-duty wall thickness, this Spiral Submerged Arc Welded (SSAW) steel pile delivers outstanding load-bearing capacity.
The continuous spiral weld seam naturally increases the pipe's outer surface roughness, significantly enhancing skin friction with the surrounding subsea soil strata. Fully compliant with international marine piling standards, this heavy-wall pile is designed to support high-capacity wharves, container berths, jetties, and breakwaters, offering superior resistance to massive lateral wave actions, vessel berthing impacts, and heavy port crane loads.
ASTM A53 ASTM A252 Grade 3 LSAW Piling Pipe 1016mm OD 16mm WT for Bridge Foundation
Engineered to support the immense structural loads of modern transportation infrastructure, this ASTM A252 Grade 3 LSAW Piling Pipe is the premier choice for heavy-duty bridge foundations and deep-water piers. Utilizing a large 1016mm nominal outer diameter and a robust 16mm wall thickness, this structural pipe pile is manufactured using the Longitudinal Submerged Arc Welding (LSAW) process. This method delivers outstanding straightness, minimal ovality, and uniform mechanical properties across the entire pipe body.
Compliant with the ASTM A252 Grade 3 standard—the industry's highest strength classification for steel pipe piles—this pile provides a minimum yield strength of 310 MPa. It is designed to act either as a high-capacity friction pile or as a permanent structural casing for bored concrete piles, offering excellent resistance to high axial compressive forces, lateral river currents, and seismic loads.
