Seamless Carbon Steel Pipe Structure Pipe Tube Heat Resistant Steel Black

Carbon steel pipes can be divided into hot-rolled and cold-rolled (drawn) steel pipes.
Hot rolled carbon steel pipes are divided into general steel pipes, low and medium pressure boiler pipes, high pressure boiler pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes.
Cold rolled (dialed) carbon steel pipes include general steel pipes, low and medium pressure boiler pipes, high pressure boiler pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes and other steel pipes. They also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, stainless thin-walled steel pipes and special-shaped steel pipes. The outer diameter of hot-rolled seamless pipe is generally larger than 32 mm, the wall thickness is 2.5-75 mm, the outer diameter of cold-rolled seamless pipe can reach 6 mm, the wall thickness can reach 0.25 mm, the outer diameter of thin-walled pipe can reach 5 mm, the wall thickness is less than 0.25 mm, and the dimension precision of cold-rolled seamless pipe is higher than that of hot-rolled pipe.
General carbon steel pipe: It is hot rolled or cold rolled with high quality carbon-bonded steel 16Mn, 5MnV or low alloy structural steel 40Cr, 30CrMnSi, 45Mn2, 40MnB etc. Seamless pipes made of low carbon steel such as 10 and 20 are mainly used for fluid transmission pipelines. Seamless tubes made of medium carbon steel, such as 45, 40Cr, are used to manufacture mechanical parts, such as stress parts of automobiles and tractors. In general, the strength and flattening test of carbon steel pipe should be guaranteed. Hot-rolled steel pipes are delivered in hot-rolled or heat-treated state; cold-rolled steel pipes are delivered in heat-treated state.

Packing Details: Bulk, Tin-bound Wooden Box Packing
Delivery details: It takes 10 days to order 20 tons of small diameter seamless steel pipe and 25 days to order 540 tons of large diameter steel pipe.

The best mode of transportation:
Shipping steel by sea, land and air is a heavy cargo product. Generally, it is better to ship steel by sea than by air. Samples should be shipped by air more quickly and conveniently.

A: We are factory.

A: Generally it is 5-10 days if the goods are in stock. or it is 15-20 days if the goods are not in stock, it is according to quantity.

A: Yes, we could offer the sample for free charge but do not pay the cost of freight.

A: Payment<=1000USD, 100% in advance. Payment>=1000USD, 30% T/T in advance ,balance before shippment.
