MAINPRESS
MAINPRESS
The MAINPRESS system is designed for heating and sanitation applications, offering quick and secure assembly with structural stability. It is suitable for multi-storey and central heating systems, particularly low-temperature systems, and sanitation systems. The system is environmentally friendly, using materials that minimize waste during assembly.
The Pipe: MAINPRESS pipes are multi-layer composite pipes made from PE-RT/Alu/PE-RT, offering 100% oxygen impermeability, making them ideal for heating and sanitation. They are resistant to corrosion and have a working temperature range of -10°C to 70°C.
The Fitting: Made from CW 617N brass, MAINPRESS fittings are suitable for drinking water and heating applications. They are corrosion-resistant and can be installed in various environments, provided certain conditions are met.
Press Connection: Pipes must be cut, deburred, and checked for correct insertion depth before pressing. Compatibility with pressing machines and jaws is specified, ensuring proper installation.
Bending and Fastening: Guidelines for bending pipes and securing them in place are provided, ensuring stability and compliance with standards.
The system supports efficient tap water distribution, adhering to relevant standards and ensuring safe and reliable water supply.
Procedures for rinsing and pressure testing are outlined to ensure system integrity and performance.
The system complies with DIN EN ISO 21003 and other relevant standards, ensuring quality and safety in its applications. It holds various approvals, including DVGW and ÖVGW certifications.
Resistance coefficients and technical properties of pipes and fittings are detailed, providing essential data for system design and installation.
- Pressing Dimension 63: The MAINPRESS multilayer composite pipe 63 can be pressed using new press jaws without adapter jaws. The press jaws must fully enclose the fitting, ensuring all parts are rectangular and flush to the fitting.
- Bending the Pipe: MAINPRESS pipes can be bent by hand or with tools, adhering to minimum bending radii. Hot bending is prohibited, and damaged pipes must be replaced.
- Pipes should be laid straight, parallel to walls, avoiding crossings to minimize construction height. Fastening materials must be suitable for the pipe material and diameter.
- Direct contact with walls and concrete is not allowed, and pipes must be protected from external influences.
- Insulation requirements differ for hot and cold water installations, with specific thicknesses regulated by DIN 1988-200 and the EnEV.
- Heating pipelines must also be insulated against heat loss, with specific requirements outlined in the EnEV 2014.
Fire protection regulations are outlined in the Model Building Code, requiring pipelines to prevent fire spread and adhere to MLAR/LAR/RbALei guidelines. Building materials must comply with DIN 4102 for preventive fire protection.
According to DIN 4109, sound insulation is crucial to prevent noise transfer in buildings. Measures include using sound-absorbing materials, proper pipe dimensioning, and sound insulation inserts. Agreements on sound insulation levels should be documented, and compliance with DIN 4109 is mandatory.
MAINPRESS system components must be protected from mechanical damage and UV radiation. Assembly guidelines include precise cutting, calibrating, and pressing of pipes. Potential equalization is not required for MAINPRESS systems, and processing temperatures should not fall below -10°C. Ethylene glycol is recommended as an antifreeze agent.
Threaded connections should follow DIN 30660, using hemp and approved sealing pastes. Contact with solvent-containing materials should be avoided. Maintenance manuals must be created for systems requiring qualified personnel, and compliance with DIN 12170 is necessary.
Proper dimensioning and hydraulic compensation are required for heating systems. Acceptance involves system testing and compliance with regulations. Maintenance and operating manuals are essential, and MAINPRESS offers free calculation programs for clients.
Planning must adhere to DIN standards, ensuring hygiene and operational safety. Proper dimensioning prevents oversized pipelines, and pressure losses must be calculated accurately. Maximum flow velocities are specified for various components.
- Drinking water is not sterile but should not affect human health. It is used for drinking, cooking, personal hygiene, and cleaning objects in contact with food or the human body.
- According to the Drinking Water Ordinance, drinking water must be colorless, odorless, pathogen-free, contain specific mineral concentrations, and be neutral and cool in taste.
- Recent changes require planners, installers, and operators to ensure high-quality drinking water up to the user's withdrawal location.
- Regulations prioritize hygienic protection, with responsibilities divided among operators, planners, and installers.
- Different distribution methods include T-piece distribution, series connection with U-shaped wall brackets, and closed circular pipelines, each with specific hygiene considerations.
- Closed circular pipelines are recommended for systems with irregular use, such as in hotels and hospitals, to minimize hygiene risks.
- Pressure and leakage testing must follow DIN EN 806-4 and ZVSHK guidelines, using compressed air, inert gas, or water.
- All components must be accessible, and a pressure test with compressed air or inert gas is recommended if water exchange is not ensured within seven days.
- Testing involves specific pressures and times, with detailed procedures for different systems (MAINPRESS, MAINPEX, MAINOX).
- Reports and certificates must document the testing process and confirm system impermeability.
- Rinsing should occur just before start-up using filtered drinking water.
- Two techniques are available: water/air mixture rinsing and water-only rinsing, each with specific guidelines.
- A report must confirm proper rinsing of the system.
- Pipe friction pressure drops are detailed based on peak flow rates and flow velocities, providing essential data for system design and analysis.
The document provides detailed tables showing the pipe friction pressure drops for water at an average temperature of 50°C with different temperature spreads (15k and 20k). The tables list various pipe dimensions and corresponding values for mass flow (kg/h), velocity (m/s), and pressure drop (Pa/m).
The document lists applicable standards and directives for heating and sanitary installations, including several DIN standards related to drinking water installations, heating systems, and pipeline systems. These standards cover technical regulations, planning, installation, and maintenance requirements.
The document includes a certificate confirming an extended warranty for DVGW certified components of the MAINPEX and MAINPRESS systems. The warranty covers defects in production or material for a period of 10 years, with specific coverage details and insurance information provided.
The MAINPRESS Pressing-System is compatible with various composite pipes and press fittings from different manufacturers, with specific compatibility requirements outlined.
The document is a technical approval-with-product certificate issued by Kiwa for MAINCOR Rohrsysteme GmbH & Co. KG. It certifies that the products comply with the Kiwa evaluation guideline BRL-K536 G for plastics piping systems intended for hot and cold drinking water transport.
