Draft Viking Johnson MaxiFit Coupling for ductile iron, steel and PVC pipes, d 57-74 mm [Code number: MF57]

Application purpose:

For connection pipes made of cast iron, steel, PVC, as well as some other materials (pipes made of PE are mounted using a sleeve) in various combinations
For neutral liquids at permissible operating temperature + 50 °С

Characteristics:

Operating pressure up to 16 bar
One type of pipe coupling made of different materials
The design provides easy and quick installation
The gap between the ends of the pipes is necessary to: compensate for thermal expansion, prevent transmission of vibration, compensate for sedimentation and facilitate installation/dismantling

Installation:

Pipes are inserted into a freely assembled freely assembled coupling, with a gap between the ends of the pipes of about 20 mm (chamfering not required)
Pressure ring bolts tighten all the way

Materials:

Pressure ring and adapter housing / Center pipe: Ductile iron according to BS EN 1563:1997
Bolts: Steel to BS EN ISO 898-1: 2009. Strength Class 4.8
Nuts: Steel in accordance with BS EN 4190: 2001. Grade 4
Sealing collar: EPDM
