Process of production
First of all, raw material uncoiling: The billet used for it is generally steel plate or It is made of strip steel, then the coil is flattened, the flat end is cut and welded-looper-forming-welding-inner and outer weld bead removal-pre-correction-induction heat treatment-sizing and straightening-eddy current testing-cutting- Water pressure inspection—pickling—final quality inspection and size test, packaging—and then out of the warehouse.
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 Welded Steel Pipe
1. Carbon steel pipes should be protected from collisions, compression, and cutting during transportation, storage, and use.
2. The use of carbon steel pipes must strictly adhere to relevant safety operating procedures to prevent accidents such as explosions, fires, and poisoning.
3. Application Scope: High-temperature, corrosion-resistant, and cold-rolled Ifcor type carbon steel pipes should be used in high-temperature environments, avoiding exposure to high-temperature and corrosive media. If exposure to such environments is necessary, please select carbon steel pipes made of special materials, such as high-temperature resistant and corrosion-resistant carbon steel pipes.
4. When purchasing carbon steel pipes, appropriate materials and specifications should be selected based on comprehensive factors such as the application environment, media characteristics, pressure, and temperature.
5. Before being put into use, carbon steel pipes should undergo necessary inspections and tests to ensure their quality meets standards.
Transportation: Express (Sample Delivery), Air, Rail, Land, Sea shipping (FCL or LCL or Bulk)
1. What is a thick-wall seamless steel pipe?
It is a seamless pipe with no weld line. Its heavy wall design makes it well suited for tough working scenarios that require high pressure resistance and strong load capacity.
2. Where are thick-wall seamless steel pipes applied?
Typical end uses cover oil & gas transmission, petrochemical plants, power facilities, heavy-duty machinery, hydraulic circuits and high-pressure pipeline networks.
3. What grades and standards do you supply?
We regularly offer ASTM A106 Gr.B, ASTM A53 and API 5L. The proper material and specification should be picked based on actual service conditions and project needs.
4. Is custom production available?
Absolutely. We can tailor outer diameter, wall thickness, cut length, steel grade and pipe end finishing within our production range to match your project specs.
5. How to select a suitable thick-wall seamless pipe?
You need to evaluate working pressure, temperature, conveyed medium, corrosion environment, plus required OD, wall thickness and governing standards. Always double-check specifications and material test certificates prior to placing orders.
