Manufacturing Process

Material Preparation: The raw material is typically a high-quality carbon steel, such as ST37.4 E235, chosen for its strength and durability.
Seamless Pipe Formation: The pipe is produced using a seamless process, which eliminates welding and ensures uniform strength across the entire pipe.
Cold Drawing: The pipe undergoes cold drawing to achieve high precision in size and smooth surface finish.
Black Oxide Coating: The steel pipe is coated with a black oxide finish to provide excellent corrosion resistance and prevent rust.
Heat Treatment: Depending on the requirements, the pipes may undergo heat treatment (annealing) to enhance mechanical properties and relieve internal stresses.
Inspection & Testing: Each pipe is subjected to rigorous quality control tests to ensure compliance with required standards. These tests include dimensional checks, pressure tests, and surface quality evaluations.

Hydraulic Systems: Ideal for use in hydraulic systems where high pressure and reliable fluid transportation are essential.
Fluid Transport: The black steel pipes are widely used for high-pressure fluid transfer in various industries, including construction, automotive, and manufacturing.
Automotive: Used in automotive hydraulic systems such as power steering, brake lines, and suspension systems.
Industrial Equipment: Commonly used in industrial machinery like presses, cranes, and other equipment requiring high-pressure fluid flow.
Construction Machinery: These pipes are perfect for use in construction equipment, such as excavators, loaders, and other heavy machinery, ensuring smooth operation and power transmission.
