China Manufacturer for Incoloy 825 Capillary String - PVDF Encapsulated 316L Chemical Injection Line Tubing – MEILONG Detail:

Product Introduction

One of the main challenges in the upstream processes of the oil and gas industry is to protect pipeline and process equipment against waxes, scaling and asphalthane deposits. The engineering disciplines involved in flow assurance play an essential part in mapping the requirements that reduce or prevent loss of production due to pipeline or process equipment blockage. Coiled tubing from Meilong Tube is applied to umbilicals and chemical injection systems play an effective role in chemical storage and delivery at an optimizing flow assurance.

Alloy Feature

Caustic environments

Austenitic steels are susceptible to stress corrosion cracking. This may occur at temperatures above about 60°C (140°F) if the steel is subjected to tensile stresses and at the same time comes into contact with certain solutions, particularly those containing chlorides. Such service conditions should therefore be avoided. Conditions when plants are shut down must also be considered, as the condensates which are then formed can develop conditions that lead to both stress corrosion cracking and pitting.

SS316L has a low carbon content and therefore better resistance to intergranular corrosion than steels of type SS316.
