This supplier offers both ERW and seamless carbon steel pipes in API 5L and ASTM grades, with diameters ranging from 2 inches to 48 inches. The material specification is clearly stated as carbon steel, with grades extending from API 5L Grade B up to X80. The listing does not specify wall thicknesses, but standard schedules such as SCH 40, SCH 80, and SCH 160 are commonly used for these sizes and grades.
ERW pipes are produced by welding rolled steel strips, while seamless pipes are formed by extrusion or piercing, offering higher pressure ratings and better resistance to internal corrosion. The supplier lists connection types including API, semi-premium, premium, semi-flush, and flush, which refer to end finishes for threading or coupling. These are critical for field assembly in pipeline construction and must match project specifications exactly.
These pipes are used in oil and gas transmission, water distribution, and structural frameworks for infrastructure projects. Buyers include engineering firms, EPC contractors, and national energy agencies sourcing for international projects. Trade terms are not detailed, but bulk shipments typically use FOB or CIF terms from Chinese ports. Buyers must confirm the exact grade, connection type, and testing requirements before order placement.

Threeway Steel Co., Ltd. is registered in Changsha, Hunan, China, with a commercial address listed but no production facility details provided. The supplier is classified as imported with harbor trust tier, indicating basic platform verification but no independent audit of manufacturing or sourcing. There is no mention of testing labs, quality control staff, or production capacity.
The listing does not state years in operation, number of employees, or export volume. No certifications such as ISO 9001, API monogram, or third-party inspection records are referenced. The supplier appears to function as a trading company sourcing both ERW and seamless pipes from third-party mills. Buyers must independently verify material origin and testing compliance for critical applications.

Before ordering ERW and seamless pipe from Threeway Steel Co., Ltd., confirm the exact API 5L or ASTM grade, connection type, and wall thickness tolerance. Request certified mill test reports for each batch, including chemical analysis and mechanical test results. Do not accept generic grade labels without supporting documentation - material traceability is essential for compliance in regulated industries.
Logistics terms are not specified in the listing. Buyers must confirm Incoterms, shipping port, container type, and lead time directly with the supplier. Standard lead times for pipe from China range from 40 to 70 days, depending on production backlog. Payment terms are typically 30% advance, 70% against BL copy. Confirm whether the supplier provides export documentation or if the buyer must arrange customs clearance independently.
Quality inspection should include dimensional checks with calibrated tools, visual inspection for surface defects, and verification of end preparation. For seamless pipe, request ultrasonic thickness mapping. For ERW pipe, require eddy current or magnetic particle inspection of the weld seam. Retain samples for third-party lab testing upon arrival. Documentation gaps are common - never assume compliance without verified test records.
