China OEM Alloy 625 Chemical Injection Line Tubing - Chemical Injection Line Tubing – MEILONG Detail:

Product introduction

A general term for injection processes that use special chemical solutions to improve oil recovery, remove formation damage, clean blocked perforations or formation layers, reduce or inhibit corrosion, upgrade crude oil, or address crude oil flow-assurance issues. Injection can be administered continuously, in batches, in injection wells, or at times in production wells.

A small-diameter conduit that is run alongside production tubulars to enable injection of inhibitors or similar treatments during production. Conditions such as high hydrogen sulfide [H2S] concentrations or severe scale deposition can be counteracted by injection of treatment chemicals and inhibitors during production.

Our tubing is characterized with integrity and quality to be specially used in subsea conditions in the industries of oil and gas extraction.

Alloy Features

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.

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.
