Find Verified Steel Pipes Suppliers, Manufacturers and Wholesalers

Steel pipes are long and hollow tubes that are used for� many different applications in a variety of places. Such as conveying fluids and powdery solids, exchanging heat, making machine parts and containers and so on. It is also an economical type of steel and� its versatility makes pipes the most often used product that is produced by the steel industry. Steel pipe production technology development began with the rise of the bicycle manufacturing, development of oil in the early years of the 19th century, two world war ships, boilers, aircraft manufacturing, after the second world war thermal power boiler manufacturing, chemical industry and the development of oil and gas drilling and transportation, effectively driving the steel pipe industry in the development of varieties, yield and quality. Steel pipe can be divided into two categories according to the production method: seamless steel pipe and seam steel pipe, seam steel pipe is divided into straight seam steel pipe and spiral seam welded pipe.

Galvanized steel pipe is the carbon steel pipe that are coated with a protective layer of zinc. The zinc layer served as a sacrificial layer, it will get rust before the carbon steel under neath it. Galvanized steel pipe is divided into cold galvanized steel pipe, hot dipped galvanized steel pipe. Galvanized layer will strengthen the anti-corrosion performances of steel pipe. 5.Galvanized steel pipe have long lifetime. But in different conditions the lifetime of use are different. Generally speaking, 13 years in heavy industrial district, 50 years for ocean environment, 104 years in suburbs, 30 years in city. In fact galvanizing have played a role of anti- rusty, it is no need other rust treatment.

Steel pipes have many different uses in manufacturing. Guardrails are one of the most common uses, providing safety features not only for stairs and balconies, but also for cyclists and pedestrians on the street. In addition., steel tubes can also be used as safety bollards to isolate vehicles and protect people, buildings or infrastructure. Third, steel pipe is also a choice for outdoor site decoration. Finally, many commercial bicycle frames are made of bent steel pipes. This has the advantage that steel's high toughness and strength make it resistant to thieves.

The most common use of steel pipes is for the transportation of products, as the characteristics of their raw materials are well suited for long-term installation. As the best way to transport oil and natural gas, steel pipe transportation has become the best choice for oil and natural gas transportation because of its larger volume and continuous flow, faster, more economical, less injection capital, less land, low cost, and the advantages of automatic control. Because of these advantages, many places also use steel pipes to transport solid energy, such as coal.
The principle of pipeline transportation is the use of the principle of the connector, through the pressure difference so that the fluid in the tube from high to low flow. During the conveying process, the pressure of the fluid decreases gradually due to friction loss and elevation difference. To pressurize the fluid, long-distance transport requires intermediate pumping or compressor stations.

Welded pipes is steel plate or steel belt, and the surface is a pipe with welding ribs after cutting, bending, welding and other processes. The main advantages of welded pipes are their lower inherent cost, narrower tolerances for wall thickness, concentricity (OD/ID) and internal surfaces that can be checked prior to manufacture. Welded steel pipe is divided into furnace welding pipe, electric welding (resistance welding) pipe and automatic arc welding pipe because of its different welding forms into straight seam welding pipe and spiral welding pipe two kinds, because of its end shape is divided into round welding pipe and special-shaped (square, flat, etc.) welding pipe. Seamed pipes offer tighter tolerances but thinner wall thickness rather than seamless pipes. Welding pipe can be used for water pipeline, gas pipeline, heating pipeline, electrical pipe and so on.

Low temperature steel pipe refers to the steel pipe used in low temperature environment below -10. The steel usually used at low temperature of -10~-196 is called low temperature steel, and the steel used at low temperature below -196 is called ultra-low temperature steel, which has enough notch toughness. Low temperature steel pipe is mainly used in the production of ethylene, propylene, urea, synthetic ammonia, compound chemical fertilizer and washing, purification, desulphurization and degreasing in pharmaceutical industry with petroleum, chemical, natural gas and coal as raw materials, as well as cryogenic equipment manufacturing, ultra-low temperature cold storage, transportation of ultra-low temperature liquefied gas pipeline and its pipe components.

High temperature steel pipe is the steel pipe used in high temperature environment. This kind of steel pipe needs to have certain high temperature resistance, will not decline in high temperature environment, but also has certain corrosion resistance.High temperature steel pipe is often used in exhaust pipe, heat treatment furnace, heat switch, incinerator and other pipeline projects that require heat resistance, because the medium in chemical pipeline, power plant boiler pipeline is mostly some high temperature gas, liquid, some also have certain corrosion.

Galvanized steel pipe USES is very wide, in addition to a general low pressure fluid such as water, gas, oil line pipe, also used as oil industry, especially the ocean oil field oil well pipe, oil pipe, chemical coking equipment of oil heater, the condensing, exchange of coal distillation wash oil cooler for pipe, and trestle pile, mining tunnel supporting frame pipe, etc. Hot dip galvanized steel pipe is widely used in all kinds of modern manufacturing industry.

Spiral steel pipe is a spiral seam steel pipe, which is made of strip coil plate as raw material, often formed by warm extrusion, and welded by automatic double-wire and double-side submerged arc welding process. Adopting advanced double-sided submerged arc welding technology, the welding can be achieved in the best position, not easy to appear the wrong edge, welding deviation and penetration defects, easy to control the welding quality.

According to the American Iron and Steel Institute (AISI), ferrous material is designated as carbon steel when its core makeup is specified to include no more than 1.65 percent manganese, 0.60 percent silicon and 0.60 percent copper and when no minimum content is specified for other alloying elements.

Carbon steel pipe enjoys wide use across many industries due to its strength and ease of workability. Because it contains relatively few alloying elements and in low concentrations, carbon steel pipe is relatively inexpensive.
