Manufacturing Process
The seamless steel tubes produced by Womic Steel undergo a rigorous and highly controlled manufacturing process, ensuring high-quality standards and performance. The process includes the following stages:
Billet Selection & Inspection:
The production begins with high-quality billets, which are thoroughly inspected for material integrity and suitability for further processing.
Piercing & Extrusion:
The billets are heated to the desired temperature, then pierced and extruded to form a hollow tube.
Cold Drawing (Cold-Forming):
The tubes are cold drawn through a die to achieve precise dimensions. This process also improves the mechanical properties of the steel.
Heat Treatment:
The tubes are subjected to heat treatment processes such as normalizing or annealing to relieve stresses and improve strength and ductility.
Pickling:
The tubes are pickled to remove surface impurities and oxides, ensuring a clean and smooth finish.
Straightening & Cutting:
After heat treatment, the tubes are straightened, cut to the desired length, and subjected to dimensional checks.
Surface Treatment:
Tubes undergo additional surface treatments, such as polishing or coating, as required by the application.
Final Inspection & Testing:
All tubes undergo comprehensive quality control checks, including dimensional verification, visual inspection, and mechanical testing.
Packaging
At Womic Steel, we prioritize the safe and secure transportation of our products. The seamless steel tubes are carefully packaged to prevent damage during transit. Our packaging methods include:
●Protection: Tubes are coated with a protective layer to prevent rust and corrosion.
●End Caps: Both ends of the tubes are fitted with protective caps to avoid dirt and moisture entry.
●Bundling: Tubes are bundled and strapped with steel or plastic bands to hold them securely.
●Shrink Wrapping: Bundled tubes are wrapped in shrink film for additional protection against dust and environmental factors.
●Labeling: Each package is clearly labeled with product information, including size, material grade, batch number, and quantity.
Transportation
●Global Shipping: We offer global delivery of seamless steel tubes, ensuring prompt and reliable transportation to any destination.
●Sea Freight & Road Transport: Tubes are shipped using sea freight (for international shipments) or road transport (for domestic and regional deliveries), with secure packaging and tracking to ensure safe arrival.
●Flat-Rack Shipping: For longer tubes, we use flat-rack shipping to prevent bending or deformation during transit.
Technical Requirements & Testing
Womic Steel's seamless steel tubes undergo the following inspections and tests to ensure they meet the highest quality standards:
1.Dimensional Inspection: Ensuring the precise dimensions of the tubes according to customer requirements.
2.Mechanical Testing: Includes tensile strength, yield strength, elongation, and hardness tests, all performed in our accredited laboratories.
3.Ultrasonic Testing: To detect any internal defects or inconsistencies.
4.Eddy Current Testing: Used for detecting surface cracks or other anomalies.
5.Hydrostatic Testing: Tubes are tested for pressure tolerance to ensure they meet safety and performance standards.
6.Visual Inspection: Every tube is thoroughly inspected for surface defects and any visible imperfections.
7.Chemical Composition Testing: To verify that the material meets the required chemical specifications.
Our in-house laboratories are equipped with state-of-the-art testing equipment to conduct all necessary tests in compliance with EN10216 and ISO 9001 standards. We also provide certified test reports for each order upon request.
