Use one product finder to organise a coordinated enquiry. The 2026 catalogue covers pipe, fittings, valves, supports, branches and installation tools.
Press connections
The catalogue press fitting range runs from DN15 to DN100. Select the exact part, outside diameter and matching connection system.
Find press fittings →Grooved connections
The core grooved fitting range covers DN125 to DN300. Build a list around the required pipe dimensions, fittings and joint components.
Find grooved fittings →The supporting components
Bring valves, mechanical branches, clamps, supports and installation tools into the same product enquiry.
Browse the full range →Core pipe range: DN15–DN300. Product tables identify SS304; ask about 316L requirements. DN is nominal, so confirm outside diameter, wall thickness, material and mating connection together. Approval scope is checked against the exact product schedule.

A useful certificate names the manufacturer and defines what it covers. We make that information part of the selection conversation.
Bring the details.

- Part numbers, sizes and quantities
- Medium, operating pressure and temperature
- Destination and required approval scheme
- Drawings, installation or traceability documents
Why do some certificates name Zhejiang Qilu or PiPress?
Zhejiang Qilu Technology Co., Ltd. is our affiliated manufacturing company. Its documents include named PiPress ranges. A brand relationship alone does not establish approval for every PIPINOX catalogue item; the supplied product must match the relevant certificate schedule.
Can you help with a project product schedule?
Use the product finder to select known parts, or send a project brief with route lengths, interfaces and service conditions. Our team can then discuss the information needed for product selection.
How do I request drawings or installation information?
Send the part number, size and question through Technical Support. Include a drawing or photo link when it helps explain the interface or installation requirement.
Start with the requirement you have.
A part number, an equipment interface or a project brief is enough to start a focused conversation.
