Введение

PPR pipe fitting crossovers are essential components in modern plumbing systems. IFAN delivers factory-direct quality that meets international standards. Our crossover fittings ensure reliable water distribution in residential and commercial projects.

What Are PPR Pipe Fitting Crossovers?

PPR crossover fittings connect perpendicular pipes without interference. They allow two pipes to cross paths while maintaining separate flow channels. This design prevents water mixing between different supply lines.

The crossover structure features four connection points. Two pipes pass through horizontally. Two additional pipes connect vertically. This configuration maximizes space efficiency in complex piping layouts.

Installation Guidelines

Preparation Steps

Clean all pipe ends thoroughly. Remove debris and contamination. Mark insertion depth on pipes. Heat fusion equipment to proper temperature.

Ensure pipes are cut square. Uneven cuts create weak joints. Use proper PPR pipe cutters only.

Fusion Welding Process

1. Heat pipe end and fitting socket simultaneously
2. Insert pipe to marked depth quickly
3. Hold joint motionless for cooling period
4. Allow complete cooling before pressure testing

Proper heating time varies by pipe diameter. Refer to IFAN installation manual for specific timing charts.

Quality Control Checks

Visual inspection reveals proper weld formation. Uniform bead around joint circumference indicates success. No gaps or voids should be visible.

Pressure testing validates joint integrity. Use 1.5 times working pressure for 30 minutes minimum. No pressure drop indicates successful installation.

Applications and Uses

Сантехника для жилых помещений

Hot and cold water distribution systems benefit from crossover fittings. Kitchen and bathroom layouts often require complex routing. Crossovers enable efficient space utilization.

Radiant heating systems use crossovers frequently. Multiple zones require separate supply and return lines. Crossovers maintain proper flow separation.

Commercial Projects

Large buildings need sophisticated piping networks. Crossovers simplify routing in mechanical rooms. Space constraints make crossovers essential.

Hotels and hospitals require redundant water systems. Crossovers enable backup line installation. Emergency water supplies remain isolated until needed.

Industrial Applications

Manufacturing facilities use crossovers for process water systems. Chemical resistance makes PPR suitable for various applications. Temperature stability handles industrial requirements.

Food processing plants require sanitary piping solutions. PPR crossovers meet food-grade standards. Easy cleaning maintains hygiene requirements.
