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:Hot galvanized steel pipe for use?
1, galvanized layer uniformity: steel pipe sample in copper sulfate solution immersion 5 times continuously, must not turn red (copper plated)2, surface quality: galvanized steel pipe surface should be complete galvanized layer, must not have plating on the black spots and bubbles exist, allow little rough surface and local zinc tumor exists.3, galvanized layer weight: according to the requirements of the buyer, galvanized steel pipe can be used for zinc layer weight determination, its average value should be not less than 500g/ square meters, and any sample shall not be less than 480g/ square meters.
Q:Difference between seamless steel pipe and welded pipe
Welding pipes can be used in water pipelines, gas pipelines, heating pipes, electrical appliances, pipelines and so on.
Q:Where is the difference between seamless steel pipe and welded pipe
In appearance, seamless steel pipe and welded steel pipe difference in the welded pipe wall welded tendons, and seamless No.
Q:What is the buckling type thin-wall steel pipe? What is a tight set of thin-walled steel tubes? What's the difference between the two?
The wire pipe thread (box, cup lock fastening points) (JDG) and buckling type (KBG) two. Products are made of high-quality steel pipe, through precise stamping molding, supply pipe and terminal box connection. The nut is hexagonal, and the convex point is punched at the six corner so as to form a good multi-point contact after being connected with the junction box.
Q:There are multiple welded galvanized steel pipe outer diameter 108mm wall thickness 4mm length of 6 meters
Galvanized steel pipe is divided into cold galvanized steel pipe, hot galvanized steel pipe, cold galvanized steel pipe has been banned, and the latter is also advocated by the state for the moment, can be used. In 60s and 70s, developed countries began to develop new types of pipes, and galvanized pipes were banned. China's Ministry of construction and other four ministries also issued a civilization, indeed from two, 000 years since the galvanized pipe as a water supply pipe, the New District cold water pipe has rarely used galvanized pipe, and some of the hot water pipe is galvanized pipe. Hot dip galvanized steel pipe is widely used in fire, power and highway.
Q:What is DN50 for welded pipe?
Refers to the use of welded steel pipe made of DN50 steel pipe, refers to the inside diameter is 50mm, the market of common DN50 pipe also refers to the 2 inch pipe, standard pipe: 3.5mm thickness, pipe diameter 60mm, the weight of 4.88kg/m theory.
Q:304 stainless steel tube with the diameter of 25*2-3 is what mean
304 stainless steel tube with the diameter of 25*2-3 said: material for 304 (the equivalent of the American brand, Chinese numbered S30408 stainless steel or 06Cr19Ni10 stainless steel), diameter (OD) for 25mm, for the seamless steel pipe wall thickness of 2 to 3mm.
Q:ASME seamless tube how to express, what is the form, I did not find on the ASME, thank God!
Welded and seamless pipe standards are ASME B31.10, no go, if you want to force a seamless tube, the request can be seamless for seamless meaning.In addition to that, the cost and difficulty of manufacturing welded pipe is higher than that of seamless tube.
Q:What steel pipes are buried for outdoor heating pipes? Seamless or welded tube? Are there any rules for specific countries? Can use the seamed tube?
The pipe material of heating pipe network should be designed according to the requirement. When the design is not specified, the following requirements shall be met:1 when the pipe diameter is less than or equal to 40mm, welded steel pipe shall be used.2 when the pipe diameter is 50 ~ 200mm, welded steel pipe or seamless steel pipe shall be used.3 when the pipe diameter is greater than 200mm, spiral welded steel pipe shall be used.
Q:Is there any difference between HFW steel pipe and ERW steel pipe?
ERW steel is high frequency ERW pipe, English Electric Resistance Welding, referred to as the abbreviation of machined steel in diameter and wall thickness of the pipe size range, with greater flexibility, especially in production
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.
