1Structure of Seamless Pipe API 5L/ASTM A106/ASTM A53 GR.B: 

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 the Seamless Pipe API 5L/ASTM A106/ASTM A53 GR.B:

• High manufacturing accuracy

• High strength

• Small inertia resistance

• Strong heat dissipation ability

• Good visual effect

• Reasonable price

Q:How can galvanized steel pipe be connected with stainless steel pipe?
Attention should be paid to the zinc coating at the side of the groove before welding. It is OK to brush silver powder after welding. There is a lot of information about the welding of carbon steel and stainless steel. Just check it online.
Q:Seamed steel pipe seamless steel pipe, carbon steel pipe, galvanized pipe, four how to distinguish between
Seamless steel tube processing technology:1.1 、 hot rolled seamless tubes are usually produced on automatic rolling mills. After checking and cleaning the surface defects, the solid tube is cut into the required length, centring on the end face of the tube blank, then sent to the heating furnace and punched 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. It is an advanced method to produce seamless steel tube by continuous rolling mill.1.2, in order to obtain smaller size and better quality of seamless tube, cold rolling, cold drawing method must be used or combined. Cold rolling is usually carried out on a two roller mill, where the steel tube is rolled in the annular groove made of variable cross section, round hole groove and stationary conical head. Cold drawing is usually performed in single chain or double chain cold drawn machines from 0.5 to 100T.1.3, the extrusion method will soon heat the tube blank in the closed extrusion cylinder, the perforation bar and extrusion rod movement, so that extrusion parts from the smaller hole extrusion. This method can produce smaller diameter steel pipe.Seamless steel pipe use: mainly used to transport fluid pipeline or structural parts.The main use of steel pipe joints (steel) two welded together, so the price is cheap, widely used.
Q:What is the outer diameter and wall thickness of DN40 steel pipe?
DN40 pipe diameter 48.3mm diameter, allowable deviation of plus or minus 0.5mm it depends on what you have, the outside diameter of 45, there are other dimensions, you can see the manual
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 are the uses of seamless steel tubes?
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, such as rolling bearing ring, Jack and so on, has been widely used in steel pipe manufacturing.
Q:Can galvanized steel tubes simmer?
I make the steel pipe, galvanized pipe and water conveying pipe material is the same, can be bent, specific to what to look at the furnace, can refer to a single material
Q:What connections are there for concrete filled steel tubular column foundations?
Strengthening ring joint is a more common in the construction of steel pipe concrete column construction, it is to beam column connection through the upper and lower plate reinforcing ring bending force transmission way is through two to strengthen the uniform arrangement between the rings radial ribs and rib structure to connect with the ring the pipe wall at the top of the plate, so as to transfer the shear stress, so as to strengthen the thickness and improve the quality of connection engineering advantage. In the process of engineering construction, according to the construction principle of longitudinal reinforcement of Deng Qiang to control, so that the smaller width of not less than the replacement of the width of the connecting plate 70%, also need to be given due attention in the form of node selection
Q:Hot galvanized steel pipe for use?
The use of hot galvanized steel pipe: mainly used for the delivery of gas, heating.In the greenhouse gas, heating, with the kind of pipe and galvanized pipe, galvanized pipe as a water pipe, produced a lot of rust in the tube, the outflow of water not only pollute the sanitary ware, and mixed with smooth inner wall corrosion caused by bacteria, heavy metal content in the water is too high, serious harm to human health. 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 have also issued a civilization, from two, 000 years since the prohibition of galvanized pipe, the current New District cold water pipe has rarely used galvanized pipe, and some of the hot water pipe is galvanized pipe.
Q:Is it good to buy a simple wardrobe or a steel pipe?
Natural nobility, if the quality and the degree of firmness, is the simple steel cloth cabinet is the best. However, because the texture of wood wardrobe, solid wood wood may be used after deformation.
Q:DN150 welded steel tubes one meter multiple
The theoretical weight table of welded steel pipe (Kg) can be checked, and the outer diameter and wall thickness can be measured according to the formula.For example: DN150 welded steel pipe, diameter 165mm, thickness 4.5mm, weight kg per meter.Welded steel pipe theoretical weight (Kg/m) = (165-4.5) * 4.5 * 0.02466=17.81Kg
