The black annealed pipe is a relatively common type of steel pipe, and it is also a type of steel pipe with a thin annealed density. Its physical properties are soft, and it can achieve the effect of not cracking and flaring. Galvanized steel pipe is the reprocessing of welded steel pipe, which is made into galvanized steel pipe by hot-dip galvanizing of welded steel pipe. For water supply, it is mainly galvanized pipes used. It is actually a steel pipe with a zinc coating. Adding zinc makes pipes more durable and also increases resistance to corrosion. Galvanized pipes have a property where the zinc starts to flake off after a while. That’s why it’s not suitable for carrying gas, as this zinc causes pipe chokes. It is very durable and lasts for over 40 years, which is why it is widely used as railings, scaffolding and all other construction projects.
Construction: used for supports, frames, columns and beams in building structures, providing the necessary strength and stability. It can also be used for architectural decoration, such as home decorations and display stands.
Machinery manufacturing industry: used to make parts, racks, machine bases and conveying systems, etc., because of its good machinability, it is easy to cut, weld and other processing operations.
Furniture manufacturing: used to make furniture such as tables, chairs, racks and shelves, providing stability and structural support.
Pipeline and pipeline systems: as a component of pipelines and pipelines, used to transport liquids, gases and solid materials, such as industrial pipelines, drainage systems and natural gas pipelines.
Transportation facilities: used in railway and highway guardrail systems, as guardrail columns and beams, providing support and protection functions.
Other fields: used in shipbuilding, power transmission and petrochemical fields to meet the specific needs of different industries.
The high strength, good toughness and machinability of black annealed tubes make them an ideal material choice in these fields.
