We specialize in welded and seamless pipes suitable for high-pressure, high-temperature, and corrosive environments, including petrochemical and heat exchanger applications.
How are pipe specifications expressed?
Specifications are defined by Outer Diameter (O.D.) and Wall Thickness (W.T.), expressed in metric (mm) or imperial units (Inch/BWG), along with standard or custom lengths.
Which international standards do you comply with?
Our products strictly adhere to ASTM A312, ASTM A269, ASME SA312, EN 10216-5, EN 10217-7, and JIS G3459 standards.
What is the Minimum Order Quantity (MOQ)?
For standard products, the MOQ is generally 1 ton. For custom or non-standard specifications, the MOQ may be higher based on complexity.
What is the standard lead time for delivery?
Lead time is usually 15 days for production. If items are in stock, they can be shipped within 7 days. Large orders (>10 tons) are subject to negotiation.
What surface roughness levels can you achieve?
We provide various finishes including BA, AP, MP, and EP. For our high-end EP pipes, we can achieve an inner surface roughness of Ra ≤ 0.10μm.
