Q:How can seamless steel tubes be produced?
After extrusion to remove pipe sizing. The sizing machine passes through the cone bit and rotates into the steel embryo at high speed to form a steel tube. The inner diameter of the steel pipe is determined by the outside diameter and length of the sizing machine. When the steel tube is fixed, it enters the cooling tower and is cooled by spraying water. The steel tube is straightened after cooling. After straightening, the steel pipe is sent to the metal flaw detector (or water pressure experiment) by the conveyor belt for internal inspection. If there are cracks in the steel pipe, bubbles and other problems will be detected. Steel pipe quality inspection, but also through strict manual selection. After the quality inspection of the steel pipe, spray with the paint on the number, specifications, production batch number and so on. The crane is hoisted into the warehouse.
Q:What's the actual size of the DN25?
Steel pipe production technology development began in the bicycle manufacturing industry rise, early nineteenth Century during the oil development, the two world war ships, boilers, aircraft manufacturing, manufacturing of power boiler after the Second World War, the development of chemical industry, petroleum and natural gas drilling and mining and transportation, are promoted in production the quality and variety, the development of steel tube industry.
Q:Why can't stainless steel be put together with carbon steel tube?
Stainless steel can not be put together with carbon steel because of galvanic corrosion
Q:How to calculate the maximum bending stress of steel pipe? Is there a list of the maximum flexural normal stresses for steel pipes of different materials and diameters?
The maximum flexural normal stress is calculated as: Sigma =M/ (gamma x*Wnx).Of which: M is the maximum bending moment of the steel tube;Gamma X - the plastic development coefficient of the cross section; for the cross section of the steel tube, 1.15,
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:What's the material of Q325 steel pipe?
Q235 refers to the material yield stress of 235MPa carbon steel, because of its low price, good machining and welding performance, it is generally used for welding structural parts. Of course, the unimportant parts can be used for it.
Q:Is there a weld on the outer wall of seamless steel tube?
Seamless steel pipe's inner wall, outer wall, section, cross section can not see the weld seam. Because seamless steel pipe is a molding product, no late roll pressure, welding and other processes. No section, inner wall, outer wall or section, as long as there is weld, it is not seamless steel tube. The inner wall can not see the outer wall of welding seam, but it can be seen that the weld products are fake or polished goods. Some products can not be seen without friction and have weld seams on the outside wall. They are seamless treated steel tubes and are polished goods. The price is much different from the real seamless steel tube. Some bad wounding, confusing concepts, earn illegal profits.
Q:How long is the seamless tube?
Generally finished seamless steel tubes are less than twelve meters, mainly for the convenience of shipment.In times of rolling (processing), the steel pipe can reach 80 meters or longer.
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;
Q:What's the difference between a cracked carbon steel tube and a liquid carbon steel tube?
Test: cracking carbon steel pipe in addition to eddy current testing, but also to do ultrasonic testing, and liquid carbon steel tubes are generally only eddy current testing.
