Factory selling Alloy 825 Hydraulic Control Line Tube - Control Line Tube – MEILONG

Product introduction

All encapsulated materials are hydrolytically stable and are compatible with all typical well completion fluids, including high-pressure gas. The material selection is based on various criteria, including bottomhole temperature, hardness, tensile and tear strength, water absorption and gas permeability, oxidation, and abrasion and chemical resistance. 

Alloy Feature

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

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.

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.
