PP-STEEL Flange

Product Description

PP-STEEL Flange is a special pipe connection method, where “PP” stands for polypropylene, a commonly used thermoplastic with good corrosion resistance and processing performance. PP-STEEL Flange is usually made by covering the polypropylene material on the steel substrate through a specific process, such as rotational molding or coating technology, to form a composite pipe fitting that combines the strength of steel and the corrosion resistance of polypropylene. This pipe fitting is usually used in industrial applications that require corrosion resistance, such as chemical plants, steel mills, sewage treatment plants, etc., to meet the challenges of various corrosive media.

Puhui Industry can provide a range of backing rings for mechanical connections in galvanised steel, stainless steel, ductile iron and polypropylene coated steel. There always using for the plastic piping system in Chemical, mining, water, petrol, etc. Systerm.

We also can provide PP reinforced, full plastic flange backing rings, and PP coated steel backing together with full range for plastic stub ends in EN, ISO, USA standard etc.

The role of PP coated steel backing

The role of PP coated steel backing is mainly to improve the corrosion resistance, aging resistance and mechanical strength of the material, while providing excellent decorative effects and beautiful appearance.

PP coated steel backing provides an additional layer of protection for steel materials by covering a layer of PP material on the steel material. This combination takes advantage of the excellent characteristics of PP materials, such as corrosion resistance, light weight, and relatively low cost. ‌This coating can not only prevent the steel material from directly contacting the external environment, reducing the possibility of corrosion and rust, but also improve the strength and rigidity of the overall structure by adding PP material. ‌In addition, PP coating can also provide different colors and surface treatments according to design requirements, thereby adding beautiful appearance and decorative effects to the product.

Advantages

1. Corrosion resistance: Polypropylene has good chemical corrosion resistance and can resist the erosion of various corrosive media such as acids, alkalis, and salts, thereby protecting the internal steel matrix from damage. ‌

2. Strength and rigidity: Due to the support of the steel matrix inside, this pipeline system has high mechanical strength and rigidity at the same time, and can withstand certain pressure and weight. ‌

3. Connection method: Flange connection is usually adopted, which is easy to install and maintain, and also improves the sealing and safety of the system. ‌

4. Customization: Support non-standard customization, can meet the needs and production requirements of different pipe diameters, and adapt to various specific industrial application scenarios. ‌
