Main Application:
1. Fluid / Gas delivery, Steel structure, Construction;
2. ROYAL GROUP ERW/Welded round carbon steel pipes, which with Highest quality and strong supply ability are widely used in Steel structure and Construction.
Note:
1. Free sampling, 100% after-sales quality assurance, Support any payment method;
2. All other specifications of round carbon steel pipes are available according to your requirement (OEM&ODM)! Factory price you will get from ROYAL GROUP.
Process of production
Initially, the raw material (steel plate or strip coil) is uncoiled and leveled. The strip is cut, edge prepared and welded form the and continuous weld with from ends. After removal of inner and outer weld bead, pipe is pre-corrected, induction heat treated, sized and straightened.
Then follows the product testing by eddy current inspection and water pressure testing, pickling, final quality inspection and dimension control. After all test is cleared, pipes are packed and dispatched.
Packaging is generally naked, steel wire binding, very strong.
If you have special requirements, you can use rust proof packaging, and more beautiful.
Precautions for packaging and transportation of carbon steel pipes
1. Carbon Steel Round Pipe must be protected from damage caused by collision, extrusion and cuts during transportation, storage and use.
2. When using carbon steel pipes, you should follow the corresponding safety operating procedures and pay attention to prevent explosions, fires, poisoning and other accidents.
3. During use, Carbon Steel Welded Pipe should avoid contact with high temperatures, corrosive media, etc. If used in these environments, carbon steel pipes made of special materials such as high temperature resistance and corrosion resistance should be selected.
4. When selecting carbon steel pipes, carbon steel pipes of suitable materials and specifications should be selected based on comprehensive considerations such as the use environment, medium properties, pressure, temperature and other factors.
5. Before carbon steel pipes are used, necessary inspections and tests should be carried out to ensure that their quality meets the requirements.
Transportation: Express (Sample Delivery), Air, Rail, Land, Sea shipping (FCL or LCL or Bulk)
Our Customer
Q1: What raw materials are used to produce steel pipes?
A: Steel plates or strip coils are used as raw materials.
Q2: What is the basic production process?
A: The process includes uncoiling, leveling, forming, welding, heat treatment, sizing, and finishing.
Q3: Why is heat treatment required?
A: It improves the mechanical properties and ensures uniform strength of the steel pipe.
Q4: What tests are performed during production?
A: Eddy current testing and hydrostatic (water pressure) testing are used to ensure quality and safety.
Q5: Why is pickling necessary?
A: Pickling removes surface impurities and improves corrosion resistance and surface quality.
