PROGEF Standard PP-H Pipe SDR7.4 PN16 d16-25

  Datasheet (PDF)

The PROGEF Standard PP-H pipe SDR7.4 PN16 is an industrial thermoplastic pressure pipe manufactured by Georg Fischer for chemical distribution, water treatment skids, and aggressive process fluid conveyance. Extruded from beta-nucleated polypropylene homopolymer (beta-PP-H), this heavy-duty piping delivers robust mechanical strength and a continuous nominal pressure rating of 16 bar at 20 degrees C across outer diameters d16 to d25 mm.

Technical specifications

PROGEF Standard SDR7.4 piping is engineered to maintain high hoop stress resistance and dimensional stability under continuous industrial operating conditions. It delivers a 25-year operational service life when conveying water and neutral media at 20 degrees C, complying with the rigorous pressure requirements of EN ISO 15494.

• Material: Isotactic beta-nucleated polypropylene homopolymer (beta-PP-H, MRS 10 MPa)
• Dimensional standard: SDR 7.4 (series S 3.2) conforming to DIN 8077 and DIN 8078
• Nominal pressure rating: PN16 (16 bar) at 20 degrees C reference temperature
• Supply format: Rigid 5000 mm pipe lengths with plain ends in pebble grey (RAL 7032)
• Manufacturing tolerances: Strict limits on wall thickness and ovality (maximum 0.015 dn)

Materials and standards

Extruded from high-grade beta-PP-H compound, this pipe exhibits exceptional resistance to stress cracking, internal abrasion, and chemical degradation from inorganic acids, alkalis, and industrial salts. The homogeneous thermoplastic structure eliminates galvanic corrosion and wall pitting, while its ultra-smooth internal bore prevents scaling and maintains low hydraulic head loss over decades of service.

Full compliance with EN ISO 15494, DIN 8077, and DIN 8078 ensures reliable hydrostatic performance in demanding industrial facilities. As an authorised Georg Fischer distributor, BigWeld supplies authentic PROGEF Standard piping systems across Europe with comprehensive manufacturer batch documentation and technical datasheets.

Installation and jointing

PROGEF Standard d16 to d25 mm pipes connect reliably via socket fusion, butt fusion, or electrofusion techniques to ensure homogeneous, leak-tight joints. For small-bore chemical dosing and distribution lines, socket fusion jointing with Georg Fischer PROGEF fittings provides rapid, clean assembly and high joint integrity without introducing elastomeric seals or mechanical fasteners.

The pipe integrates seamlessly with the complete Georg Fischer industrial portfolio, including ball valves, diaphragm valves, and PP-GF30 backing flanges. Proper thermal expansion management and correct support spacing using dedicated polypropylene pipe clips are essential for ensuring long-term operational reliability in chemical processing environments.
