Seamless Steel Pipe
Seamless Steel Pipe Manufacturer and Supplier in Indonesia
Seamless steel pipe is manufactured without a welded seam by piercing and rolling solid billets, giving it uniform strength around the circumference for high-pressure service. Sino East Steel is a seamless steel pipe manufacturer and supplier based in Tianjin, China, exporting to Indonesia and more than 50 countries for over 18 years. As a direct factory supplier with a 65,000 m2 production base and 500,000 tons of annual capacity, we deliver to Indonesian importers, distributors, contractors and project companies with complete documentation, including the Mill Test Certificate (MTC) per EN 10204 3.1 on every shipment.
Indonesian buyers choose our seamless steel pipe because every batch is tested in our ISO 9001:2015 certified quality system, packed seaworthy and shipped to Tanjung Priok (Jakarta), Tanjung Perak (Surabaya), Belawan (Medan) and Makassar within 18-25 days after production. Third-party inspection by SGS, BV or TUV can be arranged at the factory or at the destination port, and SNI documentation support is available for regulated applications.
What Is Seamless Steel Pipe?
Seamless pipe has no longitudinal weld, which makes it the preferred choice for high-pressure, high-temperature and safety-critical applications: boilers, heat exchangers, steam lines, hydraulic systems, oil and gas gathering, and structural members where weld integrity cannot be guaranteed. It is manufactured to ASTM A106 Grade B, API 5L and ASTM A53 specifications in schedules SCH20 through SCH160.
Indonesian power plants, refineries, engineering contractors and fabricators source seamless steel pipe from Sino East Steel in sizes from 1/8 inch to 24 inches, with grades from Grade B to X70 and complete MTC documentation including hydrostatic test results.

Testing and Traceability for Critical Service
Seamless pipe for pressure service must be traceable from steel billet to finished pipe. Every pipe we supply is marked with heat number and tested for chemical composition, tensile properties, hardness, dimensions and hydrostatic pressure, with results recorded in the MTC. For power and oil and gas projects we can arrange additional ultrasonic or NDT inspection by SGS, BV or TUV before shipment.
