Product Introduction

Meilong Tube's downhole control lines are used primarily as communication conduits for hydraulically operated downhole devices in oil, gas, and water-injection wells, where durability and resistance to extreme harsh conditions are required. These lines can be custom configured for a variety of applications and downhole components.

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.

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.
