Hot-selling Chemical Injection Tube - Encapsulated Control Line Tube – MEILONG

Product Introduction

Features, Advantages and Benefits

- Control lines are delivered in orbital-weld-free lengths up to 40,000 ft (12,192 m) to maximize reliability.

- A wide range of single, dual, or triple flat-packs is available. Flat-packs can be combined with downhole electrical cables and/or bumper wires for easier operation and handling during deployment.

- Welded-and-plug-drawn production method ensures a smooth, round tube to allow long-term metal sealing of terminations.

- Encapsulation materials are selected to suit well conditions, ensuring longevity and reliability.

Alloy Feature

Corrosion Resistance

Organic acids at high concentrations and moderate temperatures.
Inorganic acids, e.g. phosphoric and sulphuric acids, at moderate concentrations and temperatures. The steel can also be used in sulphuric acid of concentrations above 90% at low temperature.
Salt solutions, e.g. sulphates, sulphides and sulphites.

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.
