Frequently Asked Questions (FAQs) – Threaded Pump Connectors

Q1: What temperature and pressure ranges are typical for Threaded Pump Connectors?

A: Typical working pressures range from approximately 150 psi up to 500–600 psi (≈10–35 bar), depending on size, braid, material, and temperature. As temperature increases, pressure rating decreases. For example, stainless steel flexible hose connectors maintain full rating around 70°F (≈21–25°C) but allow lower pressure at elevated temperatures.

Q2: Which types of flanges / standards should I choose for compatibility?

A: It depends on the pipe or pump specification. Common standards include ANSI/ASME B16.5, B16.47, EN 1092-1, and ISO 7005. Choose a standard that matches or is compatible with mating flanges.

Q3: What materials are used and how do I pick?

A: Stainless steels (304, 316L, 321) are used for corrosion resistance; carbon steel (ASTM A105, etc.) for general applications; duplex stainless for aggressive, chloride, or marine environments. Material choice depends on fluid type, temperature, corrosion factors, and budget. Also consider braid type and hose construction.

Q4: Can standard dimensions be customized?

A: Yes. Many manufacturers supply custom lengths, flange drilling patterns, special flange faces, and other customizations. OEMs may require special bolt patterns, sizes, or materials. Flexible hose sections are especially customizable.
