A flange cover, also known as a Blind Flange, is a solid circular flange with no bore in the center. It is mainly used to block the end of pipelines, isolate equipment outlets, or serve as a temporary seal during system pressure testing and maintenance. The products cover the European standard system (PN series) and the American standard system (CLASS series). Types of sealing faces include Raised Face (RF), Male and Female Face (MFM), Tongue and Groove Face (TG), and Ring Joint Face (RJ). Available materials include stainless steel, duplex steel, alloy steel, and special metals such as titanium and Hastelloy. Featuring reliable sealing and easy assembly and disassembly, they are widely used in industrial piping systems for petroleum, chemical, power, pharmaceutical and other industries.

anti-corrosion steel pipes are factory-applied coated piping solutions designed to extend service life in buried, submerged, and high-humidity installations. By combining the mechanical strength of steel with advanced polymer coatings, our pipes prevent rust, pitting, and premature failure across oil & gas, water, and chemical transmission networks.

Polyurethane thermal insulation steel pipe is a high-efficiency, three-layer prefabricated composite piping system designed for underground and overhead hot medium transmission. The structure typically comprises a steel carrier pipe (inner), rigid polyurethane foam (insulation layer), and a high-density polyethylene (HDPE) outer casing (or steel outer shell). Engineered to minimize heat loss and prevent corrosion, it is widely used in district heating, hot water supply, and industrial fluid transport.

supplies plastic-coated steel pipes (epoxy/PE) from Φ21 mm to Φ1620 mm, combining steel strength with anti-corrosion coatings. Compliant with GB/T 28897, CJ/T 120, API 5L and ASTM standards. Ideal for drinking water, fire-fighting, oil & gas, and municipal projects. Custom internal/external coating solutions and mill certificates available."
