What is Sygef?

Source: GF Piping Systems. For the industrial water and chemical market, SYGEF Standard provides a premier piping system solution because of its purity characteristics, chemical resistance and extensive product and fusion offerings.

What is PVDF pipe?

PVDF Kynar Pipe. Polyvinylidene fluoride (PVDF; Kynar) is a superior thermoplastic and plumbing option among both plastic and metal pipe materials.

How is PVDF pipe joined?

The first PVDF high purity systems were joined via socket fusion. This method involves placing the end of a pipe inside the end of a fitting, melting the outside of the pipe and the inside of the connector or fitting, and pressing the two ends together.

Can PVDF be welded?

PVDF is easily welded and can be thermoformed to meet specific joining and component design requirements. Contact welding, radiant heat and RF induction are all proven ways of joining PVDF.

What is PVDF for fitting?

PVDF fittings are molded from the high purity, durable fluoropolymer polyvinylidene fluoride (PVDF). PVDF is a superior thermoplastic material in terms of its increased resistance to elevated temperatures, chemical corrosion, permeation, degradation, nuclear radiation, ultraviolet attack and growth of microorganisms.

Is Poly Pipe HDPE?

High density polyethylene (HDPE) is a thermoplastic polymer produced from ethylene, and is the material used to make Poly Pipe, also known as PE.

Can you thread PVDF pipe?

The oldest and simplest mechanical system for joining PVDF is threading. Molding or cutting threads in PVDF pipes and fittings allows joining of PVDF with itself, with metals, and dissimilar plastics.

Is PVDF a PTFE?

Summary – PVDF vs PTFE PVDF and PTFE are short terms for polyvinylidene fluoride and polytetrafluoroethylene, respectively. The key difference between PVDF and PTFE is that PVDF has comparatively a low density, whereas PTFE has comparatively a high density.

What do the stripes on poly pipe mean?

Pipe-with-the-Stripe® (PWS) polyethylene pipe features a coloured stripe extruded into the pipe wall as a permanent reminder of the grade and pressure rating.

Can you mix PP and HDPE?

The DSC and XRD results show that PP and HDPE are not compatible, and the combination of HDPE is not correlated with the crystalline structure and stability of PP.
