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:What does "spiral welded steel pipe" DN325*10 mean?
Spiral welded steel pipe with nominal diameter of 325mm and wall thickness of 10mm
Q:Will the steel tube dance?
In a single pole dance performance, the dancer moves more naturally, herself, moves and techniques, and does what she wants to do, while the style of dance is determined by herself, no one intervenes, and quite free.
Q:Is it good to buy a simple wardrobe or a steel pipe?
If the home place is big, buy Wooden, good-looking durable, if the place is small, buy cloth, easy to receive, mobile, tidy and cheap.
Q:Does seamless steel tube have a bend of 135 degrees?
Other name: 90 degree elbow, right angle bend, love bend, punching elbow, pressing elbow, mechanism bend, welding elbow, etc..Usage: connect two pipes with same nominal diameter or different pipe, make the pipe bend at 90, 45, 180 degrees and various degrees.Bending radius is less than or equal to 1.5 times the diameter of the elbow. It is 1.5 times larger than the pipe diameter and belongs to the elbow
Q:What steel pipes are buried for outdoor heating pipes? Seamless or welded tube? Are there any rules for specific countries? Can use the seamed tube?
Where outdoor heating pipes are buried, what steel pipe shall be referenced by the 11.1.2 code for installation of outdoor piping?:This chapter applies to the quality inspection and acceptance of the outdoor heating pipe network installation of the plant and the civil building group (residential area) with the saturation steam pressure not greater than 0.7MPa, and the hot water temperature not exceeding 130 degrees celsius.
Q:What does cathodic protection of steel tubes mean?
There are two ways of cathodic protection: sacrificial anode, cathodic protection and impressed current cathodic protection.Sacrificial anode: connect a living metal or alloy to a protective metal to form a galvanic cell. The active metal replaces the protected metal to lose electrons so that the protected metal is not corroded.
Q:Seamless steel pipe is how to do it?
Seamless steel tube is a kind of steel strip with hollow section and without seams. A 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. The manufacture of ring parts with steel tubes can improve material utilization, simplify manufacturing processes, save materials and work hours, such as rolling bearings, rings, Jack sleeves, etc., and have been widely used in steel pipes. Steel pipe or all kinds of conventional weapons indispensable materials, gun barrels are made of steel. The steel pipe can be divided into round tube and special-shaped pipe according to the sectional area shape. Because the circle area is the largest under the condition of equal circumference, more fluid can be transported with round tubes. In addition, the ring section in the internal or external radial pressure is more uniform force, so most of the steel pipe is round tube.
Q:How much is the tube?
The theoretical weight calculation formula of ordinary carbon steel tube is:The weight of each meter is kg/m= (outer diameter mm-, wall thickness mm) * wall thickness mm*0.02466For example: inventory 20# pipe diameter of 108*4.5 weight per meter:Kg/m= (108-4.5) *4.5*0.02466=11.485In accordance with the diameter of 108*4.5 steel pipe market price is 4500 yuan / ton as an example, we can know the diameter of 108*4.5 steel pipe per meter price: 11.485*4.5=51.68 yuan.
Q:20# seamless steel pipe and seamless steel pipe 20G what is the difference?
The difference is: 20# ordinary steel seamless steel pipe. 20G is the type of steel for high pressure boiler tubes.
