Good price Oilfield Drill Pipe  API 5DP with high quality,

1)Packaging:Steel strip or as request.

2)Delivery:Container or bundle .

3)Production Flow: Drill pipes are steel tubes with threaded ends that are used to connect a drill rig’s surface equipment with its drilling equipment, or bottomhole assembly, at the bottom of a well.They are used to transport drilling fluid to drill bits, and to raise, lower and rotate the bottomhole assembly along with the drill bit. Drill pipes must be manufactured to withstand severe internal and external pressure, distortion, bending and vibration. They are reusable and are not considered consumables in the process of exploring for and extracting oil and gas. Green pipes, raw steel tubes, are processed through a number of steps to make them into drill pipes. First, the walls of green pipes are thickened by a process called "upsetting" through which a pipe’s exterior surface is pushed inward. Next, the pipes are threaded and receive a strength-enhancing copper plating.Nondestructive quality control inspection then takes place, after which the pipes are welded to tool joints. Pipes then undergo weld heat treatments and a weld finishing processes that removes welding stress. More tests, including hardness, pressure and non-destructive inspection are carried out on the finished drill pipes before final coating and packaging.

Q:What's the actual size of the DN25?
DN25 refers to the theoretical size of the inner hole of the pipe. That is to say, the theoretical dimension of the inner diameter of the pipe is 25 (the metric tube refers to the inner diameter, and the English tube is also to indicate the inner diameter, for example: 3/8, the inner diameter is 9.525, and the diameter of the 1/2 is 12.7, and the diameter of the 5/8 is 15.875). The outer diameter is theoretical in diameter, plus the wall thickness specified by the state (which is artificially specified and has no formula)The theoretical diameter of DN25 is 25, and the outer diameter is Phi 33.7 and phi 32(but there is also the outside diameter of the mark. The mark is: the outer diameter * wall thickness, such as: 32 * 2, that is to say, the outer diameter is 30, the inner diameter is 26)
Q:The difference between carbon and welded steel tubes
Quality solutionsThe carbon steels we usually refer to include carbon structural steels and carbon tool steelsThe common steel pipe is divided into two kinds: seamless steel pipe and welded steel pipe. The welded pipe of small size is straight welded, and the big size steel pipe is usually spiral welded
Q:What is the difference between the stainless steel pipe welded pipe and seamless pipe?
Welding performance: chemical composition of seamed pipe and seamless pipe are different. The production of seamless steel components only meets the basic requirements of astm. The production of seamed tube steel containing suitable for chemical composition of welding. For example, the mixing of silicon, sulfur, manganese, oxygen, and a certain proportion of elements such as the triangle ferrite can produce a welding flux which is easy to transfer heat during welding, so as to make the whole weld be welded well. The lack of steel pipe above the chemical components, such as seamless tube, can produce all kinds of unstable factors in the process of welding, welding and welding penetration is not easy.
Q:What is the weight of hot galvanized steel tubes? DN150 4mm wall thickness
DN150 4mm wall thickness welded steel pipe theoretical weight is 16.21kg/m, galvanized steel pipe should be multiplied by the weight coefficient after galvanizing, C, DN150, wall thickness of 4mm, C=1.032, DN150, theoretical weight and wall thickness of 4mm galvanized steel is 1.02*16.21=16.7287kg/m = 16.73kg/m.
Q:What is the difference between galvanized iron pipe and galvanized steel pipe? Or called different, in fact, is referred to as galvanized pipe?
Seamless steel pipe material is steel, but also seamless, high strength, used in high pressure, harsh environment occasions. The galvanized pipe is only made on the steel tube, which is similar to the so-called antirust paint
Q:The difference between 12Cr1MoVG alloy steel tube and 15CrMo
With this kind of steel manufacturing products, usually by heat treatment (normalizing and tempering); parts made before use, usually need to go through refining or chemical surface treatment (carburizing and nitriding), surface quenching or high-frequency quenching treatment. Therefore, according to the chemical composition (mainly carbon content), heat treatment process and use of different, such steel can be roughly divided into carburizing, quenching and tempering and nitriding steel three.
Q:What's the difference between hot-rolled seamless steel tube or cold-rolled seamless steel tube?
Cold rolled seamless steel pipe (DIAL) in general, steel pipe for low and medium pressure boiler tube, high-pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking tube and other steel tube, including carbon thin-walled steel, alloy thin-walled steel, stainless steel, thin steel tube.
Q:Is the seamless steel pipe used in the market hot or cold drawn?
Small and medium-sized cold drawn and hot-rolled are many, large caliber is hot rolling, cold rolled spot less.
Q:What materials are used in scaffolding pipes?
The bamboo scaffold board made of bamboo or bamboo.
Q:What does "1.5" steel tube mean?
This is neither an outer diameter nor an inner diameter; it should be related to an English unit at the beginning of the pipeline development; it is usually used to describe galvanized steel pipes; it corresponds to the English units as follows:4, in charge of: 4/8 inches: DN15;• 6 in charge: 6/8 inches: DN20;• 1 inch tube: 1 inches: DN25;• inch two tubes: 1 and 1/4 inches: DN32;• inch half tube: 1 and 1/2 inches: DN40;- inch tube: 2 inches: DN50;• three inch tube: 3 inches: DN80• four inch tube: 4 inches: DN100;
After more than a decade’s construction and development, we have taken a leading position in seamless steel tube industry in China. In the year 2007, it awarded Famous-brand product Certificate. Besides, we have been named as excellent supplier of Qualified Products by our customers for several times.
