Q:What's the difference between steel pipe and pipe fittings?
Pipe classification: steel pipe seamless steel pipe and welded steel pipe (tube) two categories. It can be divided into round tube and special-shaped tube according to the sectional shape. The round steel tube is widely used, but there are some special-shaped steel tubes such as square, rectangle, semicircle, hexagon, equilateral triangle and octagon.
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:What's the difference between hot dip galvanizing and cold galvanizing? Which kind of galvanizing method is good?
Cold galvanizing is zinc plating, the general surface is relatively smooth, no zinc flowers, there are two kinds of resistance to fingerprints and non - Fingerprint
Q:Fastener type steel pipe scaffold steel pipe wall thickness
The scaffold steel pipe shall be made of 48.3 * 3.6 steel tube. The maximum mass of each steel tube shall not be greater than 25.8kg.Fastener type steel pipe scaffold: for building construction and build, bear the load by the fastener and steel pipe and other scaffolding and support frame, collectively referred to as scaffolding. The fastener is a fastening piece which is fastened by bolts.
Q:What's the actual size of the DN25?
Steel pipe is not only used to transport fluid and powder solid, exchange heat energy, and manufacture mechanical parts and containers, but also is an economic steel. It can reduce weight and save 20 to 40% of metal by using steel pipe to make building structure, network frame, prop and mechanical support. Moreover, it can realize factory mechanization construction. Using steel pipe to manufacture road bridge can not only save steel, simplify construction, but also greatly reduce the area of coating protective layer, save investment and maintenance cost.
Q:What quota should be installed for heating seamless steel pipe?
Installation quota of seamless steel pipe project, if it is indoor engineering, sets of welded steel pipe, the price adjustment can
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 outer diameter and wall thickness of the welded steel pipe of national standard DN250?
DN250 is the nominal diameter, the outer diameter of the steel pipe is 273mm, the thickness is above 6.5mm.
Q:What's the difference between seamless steel pipe and welded pipe?
Seamless 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 with the solid steel such as round steel, the steel tube is lighter in strength and is an economical section steel when the flexural strength and torsion strength are the same.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 circular parts, can improve the utilization rate of materials, simplify the manufacturing process, material saving and working hours, has been widely used to manufacture steel tube.
Q:304 stainless steel tube with the diameter of 25*2-3 is what mean
The quality of the steel pipe should be in line with the national standard "stainless steel seamless pipe for fluid transportation" (GBT 14976-2012) requirements.
Our product range covers include seamless steel pipes for high temperature, heat-exchanger condenser and boiler, cold drawn or cold-rolled precision pipe, fin tubes, special shaped pipes, API series oil well pipes, ASME/DIN/JIS/EN series seamless tubes. Based on strict quality control and scientific management system, the cooperation has successfully obtained International Quality System certificate of ISO9001:2000(12809Q10292ROM), monogram certificates of API 5L (5L-0596) & API 5CT (5CT-0872) and BV certificate (MAT77113-2009)for ship building usage production.
