Product Description:

1Structure of Galvanized Steel Pipe API, ASTM, DIN, JIS: 

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 was often more easily available than welded pipe. 。

 

2‍‍Main Features of Galvanized Steel Pipe API, ASTM, DIN, JIS:

• High manufacturing accuracy

• High strength

• Small inertia resistance

• Strong heat dissipation ability

• Good visual effect

• Reasonable price

Q:How long are the seamless tubes? Are they six meters long?
The usual length of steel pipe is as follows: hot rolled steel pipe 3000~12000mm and cold drawn steel pipe 3000~10500mm.
Q:What type of steel pipe for security windows?
General anti-theft window through the round tube is 3 cm square tube, 22.5 mm diameter round tube, also can use all square tube to do, if you want to median 304, the pipe is estimated more expensive, the market to do the price in 60 to 110 range. As for plastic steel, Anhui conch brand, the price of 180 this way. Aluminum alloy 110 to 230 specific look what material?!
Q:What is DN50 for welded pipe?
Commonly used in the market DN50 seamless steel pipe, the outer diameter has two specifications: A, 57mm, B, 60mm, if no special instructions, commonly used is 57mm. The outer diameter of the welded pipe is only 60mm this specification.
Q:What is the size of seamless steel tube DN150?
Seamless steel pipe having a hollow cross section, used as a conduit for conveying fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials. Compared withsteel and roundsteelinsolid, flexural torsional strength in the same time, the weight is light, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, the bicycle frame and steel construction with scaffold with steel pipe manufacturing ring parts can be improved the utilization rate of materials, simplify the manufacturing process, material saving and working hours, has been widely used to manufacture steel tube.
Q:Difference between seamless steel pipe and welded pipe
Welded steel pipe for different welding process and divided into the furnace pipe welding (ERW) pipe and automatic arc welding, because of the different forms of welding seam welded pipe and spiral welded pipe is divided into two kinds, end its shape is divided into circular welded and shaped (square) pipe etc..
Q:Is there any difference between thermal expansion seamless steel pipe and seamless steel pipe?
Seamless tubes are generally produced on continuous tube mills, also known as automatic rolling mills. The round steel is cut into the required length, centering on the end face of the pipe blank and then sent to the heating furnace to punch on the piercer. At the same time, the hole rotates and advances continuously. Under the action of the roller and the plug, the inner cavity of the pipe blank is gradually formed, and the cavity is called the capillary. Sent to the automatic tube rolling mill on rolling. Finally, the thickness of the whole machine is the same, and the diameter of the sizing machine is determined to meet the specifications.
Q:What are the main types of steel pipe ah? How to judge which kind of steel pipe performance is better?
Welded steel pipe for different welding process and divided into the furnace pipe welding (ERW) pipe and automatic arc welding, because of the different forms of welding seam welded pipe and spiral welded pipe is divided into two kinds, end its shape is divided into circular welded and shaped (square, flat) pipe.The welded pipe is rolled into the steel tubular to sew or spiral seam welded in the manufacturing method, and is divided into low pressure fluid delivery with welded steel pipe, spiral welded steel pipe, welded steel pipe, welded pipe roll etc.. Seamless steel pipe can be used in various industries, such as liquid, pneumatic, pipeline and gas pipeline. Welding pipes can be used in water pipelines, gas pipelines, heating pipes, electrical appliances, pipelines and so on.Press materialSteel pipe according to the pipe material (ie steel) can be divided into: carbon tube and alloy tube, stainless steel tube.Carbon tube can be divided into ordinary carbon steel tube and high quality carbon structure tube.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 does "1.5" steel tube mean?
DN refers to the nominal diameter of the pipe (also known as nominal diameter), all piping accessories in the piping system are numerically represented in order to distinguish the parts that are represented by threads or outside diameters. Nominal diameter is used as a reference, after rounding the figures, and processing numerical value is not exactly the same, nominal diameter can be expressed as metric mm, also can be used in English in.
Q:Who knows what is the difference between double submerged arc welded pipe and longitudinal submerged arc welding?
Double submerged arc welding should be for spot welding and single side welding, they are straight line welds, but double submerged arc welding seam is more beautiful and fine.
Q:45 and 316 which steel tubes are of high hardness?
316 stainless steel by adding Mo element, the corrosion resistance, and high temperature strength has greatly improved, high temperature can reach 1200-1300 degrees, can be used in severe conditions. 316F stainless steel is easy to cut stainless steel with high sulfur content. Good corrosion resistance, easy processing, good smoothness, suitable for axial parts.
