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: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:Seamless steel tube with the tube with what is the difference?
At present there are some seamed steel pipe seamless treatment tube, it is the weld annealing treatment, eliminate the residual stress of the weld, the weld and base material, the pressure range of basic and seamless pipe is. May also consider the use of.
Q:What is PE coated steel pipe? Seek explanation
PE pipe is a kind of thermoplastic resin with high crystallinity and non polarity.
Q:What does "spiral welded steel pipe" DN325*10 mean?
Labeling is wrong: it should be said for 325*10, the diameter of pipe wall thickness of 10, 325;For example, the nominal diameter shall be: DN300.
Q:What's the difference between hot-rolled seamless steel tube or cold-rolled seamless steel tube?
Cold rolled seamless steel pipe (DIAL) in general, steel pipe for low and medium pressure boiler tube, high-pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking tube and other steel tube, including carbon thin-walled steel, alloy thin-walled steel, stainless steel, thin steel tube.
Q:What is lined pipe?
There are inner pipe jacket, such as day, tube, etc.; there are outside the pipe painted, such as large-diameter water pipes. An internally coated steel pipe for corrosive medium fluids replaces the expensive stainless steel pipe.
Q:Hot galvanized steel pipe for use?
1, galvanized layer uniformity: steel pipe sample in copper sulfate solution immersion 5 times continuously, must not turn red (copper plated)2, surface quality: galvanized steel pipe surface should be complete galvanized layer, must not have plating on the black spots and bubbles exist, allow little rough surface and local zinc tumor exists.3, galvanized layer weight: according to the requirements of the buyer, galvanized steel pipe can be used for zinc layer weight determination, its average value should be not less than 500g/ square meters, and any sample shall not be less than 480g/ square meters.
Q:What is the difference between seamless steel pipe and welded pipe?
The main molding process is different. Ordinary steel pipes, such as tap water pipes, are usually welded by bending flat plates, and you can find a seam on it;
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.
All these steel pipes are suitable for the industries of oil, natural gas,ship building,chemical, environmental protection,boiler, water conservancy, electrical industry,steel structure, building and other related fields.Our company following the principle that ‘customer supemacy, business integrity’We will do our best to supply best products and service to our customers. We expect mutual benefit.
