Wound PPH Vacuum Metering Tank

• Made from PPH raw material using German spiral winding technology to form a seamless, weld-free tank body
• Suitable for metering, vacuum buffering, drip feeding, and head tank storage
• Resistant to corrosion and aging from most organic and inorganic acids, alkalis, salts, and some organic solvents
• Suitable for atmospheric pressure and vacuum conditions, with a vacuum degree of up to ≤ -0.095 MPa
• Operating temperature range of -10°C to 100°C; weighs 40%–60% less than stainless steel tanks

The Wound PPH Vacuum Metering Tank is made from PPH raw material using German spiral winding technology. Unlike tanks assembled by manually butt-welding plastic plates, its one-piece winding process produces a seamless tank body without spliced welds, reducing the risk of leakage and stress cracking caused by secondary processing.
It is used in production processes that require metering, vacuum buffering, drip feeding, or head tank storage. The material offers resistance to most organic and inorganic acids, alkalis, salts, and some organic solvents, including weak acids, weak bases, and alcohol-based media. Compatibility should be confirmed for the specific chemical and operating conditions.
The tank is suitable for atmospheric pressure and vacuum applications, with a vacuum degree of up to ≤ -0.095 MPa. The general operating temperature range for PPH material is -10°C to 100°C. Its lightweight construction makes it 40%–60% lighter than stainless steel and other metal tanks, helping reduce transportation, installation, and foundation requirements. Aging-resistant and UV-resistant materials are added during production to support long-term use.

Taizhou Yifan Environmental Protection Equipment Technology Co., Ltd. operates a 19,000-square-meter factory in Taizhou, Zhejiang, with 68 workers. The company has experience supplying vacuum metering equipment for fine chemical enterprises.
OEM and ODM services are available. Tanks can be manufactured according to customer drawings or prototypes. For each Wound PPH Vacuum Metering Tank, the working vacuum degree, operating temperature, metering volume, interface positions, and accessory configuration are confirmed before production.
The production process includes PPH raw material inspection, spiral winding, flange and interface welding, water-fill leak testing, and final inspection.

Please provide the required working vacuum degree, operating temperature, metering volume, and interface positions so that the tank configuration can be confirmed. Drawings or prototypes are also welcome for customized production.
