Industrial Carbon Steel Pipe Range | SMLS, ERW, LSAW & Coated Pipes

Our facility in Cangzhou, Hebei, operates with a 35,000+ sqm production base, delivering over 90 containers per month to global distributors and engineering contractors.

1. Seamless Carbon Steel Pipes (SMLS)
The seamless carbon steel pipe is the gold standard for high-pressure integrity. Manufactured by piercing solid steel billets, our SMLS pipes have no weld seams, ensuring maximum safety in extreme conditions.

Standards: ASTM A106 Grade B, ASTM A53, API 5L, DIN 17175.
Sizes: 1/4″-36″ NPS, wall thickness:1.25mm to 50mm
Applications: Seamless carbon steel pipe for high temperature service, high-pressure boilers, and chemical refineries.
Why Jinsheng SMLS? Our pipes undergo 100% hydrostatic testing and ultrasonic inspection to ensure zero-defect performance.
2. ERW (Electric Resistance Welded) Pipes
Our ERW carbon steel pipes are produced by cold-forming steel strips into a round shape. They offer a cost-effective solution with tight dimensional tolerances and uniform wall thickness.

Standards: ASTM A53, API 5L, EN 10217.
Features: High-quality longitudinal welds with minimal heat-affected zones.
Best For: Low to medium pressure fluid transport, scaffolding, and structural supports.
Sizes: OD:1/8″ to 24″, Wall thickness: up to 26.5mm
3. LSAW (Longitudinal Submerged Arc Welded) Pipes
For large-diameter requirements and heavy-wall thickness, our LSAW pipes provide superior structural stability.

Process: Formed from heavy steel plates using JCOE or UOE technology.
Specifications: Large diameters up to 56 inches.
Ideal for: Onshore and offshore oil and gas pipelines that require high strength and high resistance to deformation.
Sizes: OD:16″ to 64″ , Wall thickness: max 65mm
4. SSAW (Spiral Submerged Arc Welded) Pipes
SSAW carbon steel pipes are manufactured by rolling steel strips at a specific spiral angle. This allows for the production of very large diameter pipes using narrower steel strips.

Advantages: Excellent versatility in sizes and lower production costs for large-scale projects.
Applications: Water transmission, piling projects, and low-pressure industrial piping.
Sizes: OD:219mm to 3120mm, Wall thickness: 3mm to 25mm
5. Industrial Coated Steel Pipes
To extend the service life of pipelines in corrosive environments, we offer professional coated carbon steel pipes. We specialize in external and internal protection layers.

any size can customed.

Benefit: Prevents oxidation and chemical corrosion, reducing long-term maintenance costs for underground pipelines.

Coating Types: 3PE (Three-Layer Polyethylene), FBE (Fusion Bonded Epoxy), Black Bitumen, and Galvanized.
