PUF ZP pipes with tracer
A ZP PUF pipe with tracer is a steel pipe assembled with an additional small-diameter tracer pipe inside the PUF insulation and protective layer of zinc-plated steel.
The tracer acts as a heater for the heat carrier and eliminates the risk of the working medium freezing.
Identification code review
Russian abbr.: Труба Ст 10 — Ст 20 (ГОСТ 10704—91/10705—80) 108x3,5 — 1 — ППУ ОЦ со спутником DN32
English abbr.: Pipe St 10 — St 20 (GOST 10704—91/10705—80) 108x3,5 — 1 — PUF ZP with tracer DN32
Below is the explanation of the pipe’s marking conventions:
- «St 10 - St 20» is the pipe steel grade;
- «GOST 10704—91/10705—80» - longitudinal electric-welded pipe;
- «108» is the pipe diameter;
- «3,5» is the pipe wall thickness;
- «1» is the pipe type (affects the insulation thickness);
- «PUF – ZP» - polyurethane foam insulation, zinc-plated protective shell;
- «DN32» is the tracer pipe diameter.
