Frequently Asked Questions

How Can I Request Franta Product Samples, Technical Documents, Product Selection Support, or a Project Quotation?

You can obtain relevant product information through the Franta website, download center, or contact channels. For projects requiring further product selection support or a quotation, please provide details such as the product name, specifications, quantity, application, and basic project information. Based on your actual requirements, Franta’s sales or technical team can provide product documentation, selection recommendations, sample support, and quotation solutions.

Does Franta Support Bulk Project Supply and Complete Stainless Steel Piping System Solutions?

Yes. Franta offers a comprehensive product range that includes stainless steel pipes, press-fit fittings, grooved fittings, flanged fittings, valves, manifolds, O-ring seals, pipe supports, fasteners, and installation tools. Based on project requirements, Franta can provide systematic product selection and coordinated supply of piping system components, helping reduce compatibility issues between different products and streamline the procurement process.

What Information Is Required to Request a Quotation for an Engineering Project?

To improve product selection and quotation efficiency, please provide information such as the project type, conveyed medium, required material grade, pipe size or specification, connection method, quantity, project location, and any special operating conditions. If design drawings, material lists, or technical specifications are available, they can also be provided. Franta can use this information to recommend suitable products and prepare an accurate quotation.

Does Franta Offer OEM and ODM Services for Stainless Steel Water Tanks?

Yes. Franta provides OEM and ODM services for stainless steel water tanks. Based on project and market requirements, we can discuss customization options for tank dimensions, structural design, surface treatment, accessories, and packaging. OEM and ODM solutions are developed according to the specific requirements and conditions of each order.

What Materials and Manufacturing Processes Are Used for Franta Stainless Steel Water Tanks?

Franta stainless steel water tanks are primarily made from high-quality stainless steel materials. Depending on the product design, manufacturing processes may include forming, welding, and surface treatment. Throughout production, quality control is carried out at key stages such as incoming material inspection, forming, welding, and surface finishing to meet different requirements for tank structure, dimensions, and surface appearance.

What Inspections and Tests Are Required After Installing a Stainless Steel Piping System?

After installation, the pipes, fittings, insertion depth, pressed joints, and pipe supports should be inspected to ensure they have been installed correctly. Pressure testing or other leak-tightness tests should then be carried out in accordance with the applicable project specifications. For concealed piping, the system should be fully inspected and accepted before walls or ceilings are closed or subsequent finishing work begins, ensuring that all requirements are met before proceeding to the next stage of construction.

Which Applications Are EPDM, FKM, and HNBR O-Rings Best Suited For?

Different O-ring materials offer different levels of temperature resistance, chemical compatibility, and aging resistance. EPDM is commonly used in water supply and conventional hot water systems, while FKM is better suited to higher-temperature conditions and certain special media. HNBR can be selected for specific industrial media and operating conditions. For each project, the sealing material should be chosen based on the conveyed medium, operating temperature, system pressure, and technical requirements rather than by color alone.

How Are Press-Fit Stainless Steel Pipe Connections Sealed, and Are They Reliable?

Press-fit stainless steel pipe connections rely on the pipe, fitting socket, O-ring seal, and a dedicated press tool working together to create a secure joint. During installation, the pipe is inserted into the fitting to the specified depth, and the fitting socket is then mechanically pressed with the proper tool. This creates a stable connection between the pipe, fitting, and sealing ring. The reliability of the connection depends on both the precision of the piping components and correct installation in accordance with the specified procedures.

What Is the Franta Active Water System, and How Is It Different from a Traditional Home Water Supply System?

The Franta Active Water System uses looped piping design and dynamic circulation components to keep water moving and refreshed within the piping system, helping reduce long-term water stagnation in certain pipe sections. Unlike traditional home water supply systems that primarily focus on delivering water from one point to another, the Active Water System places greater emphasis on continuous water movement, circulation management, and the overall household water-use experience.
