FEP Encapsulated 316L Chemical Injection Line Tube

Short Description:

To assure produced fluid flow and protect your production infrastructure from plugging and corrosion, you need reliable injection lines for your production chemical treatments.

The length without orbital welds which reduces the potential for defects and failures. Additionally, our coils have an extremely clean and smooth inside surface that is ideal for chemical injection systems. The coils offer short hydraulic response time, greater collapse strength, and elimination of methanol permeation.

Alloy Feature

SS316L is an austenitic chromium-nickel stainless steel with molybdenum and a low carbon content.

Application

TP316L is used for a wide range of industrial applications where steels of type TP304 and TP304L have insufficient corrosion resistance. Typical examples are: heat exchangers, condensers, pipelines, cooling and heating coils in the chemical, petrochemical, pulp and paper and food industries.
