Product Description:

1、Structure of Seamless tube ASTM A106/53: 

Seamless pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable. Historically seamless pipe was regarded as withstanding pressure better than other types, and we are trying to provide best service what we can, and we produce any pipe and to meet silent's demand just like API 5L, API 5CT, ASTM A106/A53 serious and etc.


2、‍‍Main Features of the Seamless tube ASTM A106/53:

• High manufacturing accuracy

Q:What is an electric welded pipe (EFW)? Seek help!
Pipe and pipe fittings should be suitable for the gap, usually with micro force insertion is appropriate, the gap is too large or too small will affect the quality of the interface.Check the depth of the plug and slip the spigot into the socket and position correctly.
Q:What type of steel pipe dance is used in general?
The steel pipe fittings used in the pipe dance are made of smooth surface material, usually chrome or polished by steel or iron.
Q:What are the specific differences between flexible pipes and rigid pipes?
Choose from the waterproof performance:A rigid waterproof sleeve is a steel pipe with an outer wing (a steel ring made of a steel ring), mounted in the wall (mostly concrete walls), used for general pipe wall crossing, and is beneficial to the waterproof of the wall;The flexible waterproof casing except external wing ring, flange ring and internal wire like, and have complete sets sold, but also their own processing, for pipeline damping needs, such as pipes and pumps connected through walls.
Q:Which is more load-bearing, the same thickness of steel pipe and steel bar?
The same length, the same pipe diameter, the same material strength is hollow, the ratio of area of steel (solid), and the cyclical and slender radius smaller than the larger, so the longitudinal stability coefficient is smaller, three factors, two factors are weak in steel reinforced, another factor: strength, they are the same, no doubt, steel reinforced bearing less than.
Q:Galvanized steel pipe, PPR pipe, PE pipe, U-PVC pipe and HDPE double wall corrugated pipe and what is the difference between the characteristics of
PE pipe, polyethylene pipe, the past is also commonly used in low temperature water, but because of its short life now use less prone to aging, more PE material for the production of plastic bags;
Q:What are low-pressure carbon steel tubes?
Any of various steels that contain less than 2.11% of the mass of carbon but contain no alloying elements. Sometimes referred to as plain carbon steel or carbon steel.Carbon steel, in addition to carbon, usually contains a small amount of silicon, manganese, sulfur and phosphorus.1) according to the use of carbon steel can be divided into carbon structural steel, carbon tool steel and easy to cut structural steel three categories, carbon structural steel is divided into engineering construction steel and machine manufacturing structural steel two kinds;(2) by refining methods can be divided into open hearth steel, converter steel;(3) according to deoxidization methods, they can be divided into boiling steel (F), killed steel (Z), semi killed steel (b) and special killed steel (TZ);(4) according to the carbon content of the steel can be divided into low carbon steel (WC = 0.25%), carbon steel (WC0.25% - 0.6%) and high carbon steel (WC>0.6%);(5) according to the quality of steel, carbon steel can be divided into ordinary carbon steel (phosphorus, sulfur, higher), high quality carbon steel (low phosphorus and sulfur) and high quality steel (lower phosphorus and sulfur) and super quality steel.Description: the carbon content in general carbon steel is higher, the hardness is higher, the strength is higher, but the plasticity is lower.
Q:Are metal spiral tubes the same as metal bellows?
The spiral pipe is mainly used in the pipeline of petroleum and natural gas, and its specifications are indicated by outer diameter * wall thickness.
Q:How to distinguish between steel pipe and spiral pipe material?
The alloy tube can be divided into: low alloy pipe, alloy pipe structure, high alloy tube, high strength tube. Bearing tube, heat resistant acid resistant stainless pipe, precision alloy (such as cutting alloy) pipe, high temperature alloy tube, etc..
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 nut body and the junction box are connected at one end by adopting metric fine tooth thread, and the pipe is connected with the pipe, and one end is the same as the straight pipe joint (direct). Withhold the box joint points inside and outside teeth two. The diameter of straight pipe joint is divided into 16mm, 20mm, 25mm, 32mm, 40mm, 50mm.
Q:The difference between carbon and welded steel tubes
Seamless steel pipe because there is no weld, so can withstand greater pressure, boiler tubes are generally used seamless steel pipe
