Black steel pipe price list

Currently, on the market, there are many types of black steel pipe used in fire protection systems, steel pipes for water supply systems, and good quality gasoline pipes.

What information do you need to buy a black steel pipe?

• Steel pipes have easily distinguishable characteristics: the steel is dark blue or has an anti-oxidation paint layer on the outside.
• Steel pipes are made from high-quality steel plates, so they can withstand large loads without corrosion and are used in the construction industry.
• Black steel pipes are produced using modern technology.
• The metal is hot-rolled and made from sheet metal.

The price list of black steel pipe all types is always changing:

• In 1815, inventor William Murdock developed a coal lamp system that allowed gas to pass through a steel tube made of gunpowder.
• In 1824, James Russell invented a method of making steel pipes by tying flat metal sheets and welding them together.
• 1925 – Cornelius Whitehouse develops “butt welding” welding technology as the basis for modern steel pipe production.
• 1911: John Moon refined Whitehouse welding technology on an industrial scale, allowing the continuous production of seamless steel pipes similar to today’s black steel pipes.

Black steel pipes and galvanized steel pipes have many similarities:

• Made of steel, resistant to high-pressure loads, and sturdy, both types of steel are galvanized (Cavanay)
• In particular, black steel pipes are cheaper than galvanized steel pipes.
• Galvanized steel pipes are rarely utilized to transport air or water, instead opting for black steel pipes.
• Because galvanized steel has an exterior layer of zinc that peels off over time, the pipe is less likely to split or leak.

Using black steel pipe specification table:

• Black steel pipes have good durability, so black steel pipes can be widely used in many fields.
• It has high durability so it is used in water supply and drainage in fire protection systems.
• Used for oil pipelines, drilling rigs, water wells, and oil drilling.
• The price is cheaper than stainless steel and seamless steel, so it is widely used in industry and construction.

Black steel pipe production process:

• With the help of modern machinery and technology, black steel pipes are produced at high temperatures and pressures.
• Make high-quality, high-productivity products.

The black steel pipe production process includes the following steps:

• B1: Prepare the sheet metal.
• B2: Forms black steel pipes.
• B3: Weld into tubular shape: Weld cut and polish the seams.
• B4: Adjust the tube into a round tube: cut deeply and straight.
• B5: Quality inspection.
• B6: Packaging and Shipping.
