Q:How can seamless steel tubes be produced?
Tube mill, round tube billet, heating, perforation, three roll cross rolling, rolling or extrusion, removal of pipe, sizing (or reducing diameter), cooling, straightening, water pressure test (or flaw detection), marking, storage, cold rolling and hot rolling. Generally cold rolling, because of high accuracy.
Q:SC15 what does galvanized steel pipe look like?
Ordinary galvanized steel pipe, the outer diameter is 1.5 inches
Q:What does the diameter of a steel pipe project mean?
Suppose we specify a standard that defines the nominal diameter of the same steel tube as G-1, then this G-1 is the same as DN50.I hope it doesn't make you any more confused, huh?. If you still don't understand, keep in mind that the nominal diameter is neither outside nor inside diameter.
Q:What is the difference between the stainless steel pipe welded pipe and seamless pipe?
Concentricity: seamless tube manufacturing process is the temperature of 2200 degrees F in stainless steel billet stamping a hole, at this high temperature, tool steel by stamping and drawing become soft and spiral form from the hole. Thus, the wall thickness of the pipeline is uneven and the eccentricity is high. Thus ASTM allows seamless pipe wall thickness ratio of the wall thickness difference of seamed tube. Through the seamed tube cold rolling plate precision (per roll width is 4-5 feet) made. These cold rolled plates usually have a maximum wall thickness of 0.002 inches. The steel plate is cut into a width of PI D, in which D is the outer diameter of the pipe. Tube wall thickness tolerance is very small, and the entire circumference of the wall thickness is very uniform.
Q:What connections are there for concrete filled steel tubular column foundations?
The Liang Duan local widening joint is achieved by the continuous construction of longitudinal steel bars around the steel tube. At the beginning of the creation of additional stirrups should be widened longitudinal reinforced wrap, Liang Duan local widened joints of steel reinforced concrete beam and corbel overlapping transition zone can transmits beam internal force, bending steel bracket in both shear and participation. The node form is used in building engineering in Xiamen. The force transfer path of this joint is clear and reliable, with less welding on site and more convenient for construction. This kind of node passes shear stress through the bracket, and the stress is more concentrated.
Q:Are galvanized steel tubes the same as degaussing steel tubes?
Also known as galvanized steel pipe, hot galvanized and galvanized two kinds, hot galvanized, zinc coating thickness, with uniform coating, adhesion, and long service life. The cost of galvanizing is low, the surface is not very smooth, and the corrosion resistance of itself is much worse than that of galvanized pipe.
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 thread of the tightening (JDG) joint is unified with an outer thread, a wall thickness of 1.5mm, and a button (KBG). The thread of the joint is an internal thread, and the wall thickness is 1.0mm. Withholding type joint for the use of the same company and pipe connection to matching products with complete connection clamp buckle. Fastening and pressing type correctly connected and locked after no need to do a cross ground.
Q:How do you solder purple copper plate and steel tube?
When the copper pipe and the size is not too large, such as 10 mm below the pipe welding, brazing is suggested, with brass solder, such as Wei Odin 201 solder, with supporting solder paste, with a neutral flame welding, the copper plate is heated to about 800 degrees, and then use the solder with 201 Wei Odin 201-F in solder welding, welding wire with melt molding.
Q:Is the diameter of the steel tube indicated by the outer diameter by the wall thickness or by the inside diameter by the wall thickness?
Seamless steel pipe specifications are: outer diameter, wall thickness, material. Three of these reflect its main features.Welding pipe specifications are: nominal diameter (internal diameter), galvanized or non plated
Q:What is the weight of hot galvanized steel tubes? DN150 4mm wall thickness
GB/T3091-2008: DN150 welded steel pipe, wall thickness of 6mm, the theory of the weight of welded steel pipe 24.02kg/m, galvanized steel pipe should be multiplied by the weight coefficient after galvanizing, C, DN150, wall thickness of 6mm, C=1.02, DN150, theoretical weight and wall thickness of 6mm galvanized steel 1.02*24.02= 24.5kg/m.
We specializes in producing steel tube used the following criteria, in the pursuit of brand quality, while providing professional branding services: | 1. Professional production of ASME Series: T91, T23, T22, T12, T11, T2, etc., steel appearance, size and internal performance indicators comparable with the imported products and strive. | 2. A full range of professional production internally ribbed tube, especially supercritical internally ribbed tube. Finished internally threaded tube with threaded inspection by the root. | 3. A boiler tube free pretreatment process: steel pipe in the regular inspection process is completed.
