Our pp plastic elliptical head is an integrated hot‑formed anti‑corrosion end cap manufactured by Henan Yuanfang Environmental Protection. This pp plastic elliptical head is widely matched for PP storage tanks used in wastewater, chemical and electroplating projects.

Why Choose Our PP Plastic Heads?

Every industrial anti-corrosion tank system lives or dies by the reliability of its end closures. A leaking head means downtime, medium loss, equipment corrosion and even safety incidents — costs that far exceed the component itself. Henan Yuanfang Environmental Protection manufactures PP plastic heads engineered precisely to eliminate that risk.

Built from the Right Raw Material

We use premium modified polypropylene, selected and batch-tested in-house. The result is outstanding resistance to most acids, alkalis, salt solutions and organic solvents, with a working temperature range of -10℃ to 80℃ under normal-pressure anti-corrosion conditions. Unlike welded or FRP assemblies, our heads are integrally hot-formed in one piece. There are no seams, no weld lines, no hidden leakage paths — the single most common failure point in tank closures is simply designed out.We provide a full size range for the pp plastic elliptical head from DN250 to DN3500, including standard‑wall and thickened reinforced types.

Quality You Can Verify

Before every shipment, each head passes dimensional inspection, wall-thickness testing and a full appearance check. Surfaces are smooth, free of cracks, bubbles and uneven deformation, which prevents medium residue and secondary corrosion during service. We are happy to provide technical parameters, dimension sheets and inspection documents to support your customs clearance and project acceptance.Each pp plastic elliptical head is inspected for dimension, wall thickness and surface finish before shipment.

Lower Total Cost, Not Just Lower Price

Our PP heads weigh far less than stainless steel or FRP alternatives, which cuts freight cost and makes on-site installation faster and safer. There is no anti-rust maintenance after installation, and the long service life directly reduces your replacement and downtime budget. This is why customers measure us by total cost of ownership, not unit price alone.

Industries We Serve

Our PP plastic heads are widely installed in wastewater treatment, chemical processing, electroplating, new-energy wet metallurgy and flue-gas desulfurization projects. Clients across Southeast Asia, the Middle East and Europe rely on us for stable quality and dependable delivery. We understand that different regions apply different engineering standards, and we provide the corresponding documentation to help you close orders and clear customs smoothly.

A Partner for Your Whole Project

Beyond PP heads, we supply PP tanks, pipes, fittings and matching accessories, giving you a one-stop anti-corrosion package from a single responsible manufacturer. Our factory operates independent production workshops with mature thermoforming equipment and an experienced technical team. Samples are available for your evaluation before bulk orders.
