Q:How long are the seamless tubes? Are they six meters long?
6 meters of a root in general need to be customized, seamless tubes are mostly seven meters above the variable foot
Q:Is steel pipe made of profiles?
According to the shape of the cross-section, the steel is generally divided into profiles, plates, pipes and metal products in four categories.Therefore, the steel pipe belongs to the pipe, not the profile.
Q:What is the size of seamless steel tube DN150?
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 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 with steel pipe manufacturing ring parts can be improved the utilization rate of materials, simplify the manufacturing process, material saving and working hours, has been widely used to manufacture steel tube.
Q:What quota should be installed for heating seamless steel pipe?
Should be in low carbon steel welding installation set industrial pipeline engineering quota, material to input the name and type of seamless steel pipe specifications and price; according to the description of the contents of related items can be set.
Q:What is the outer diameter and wall thickness of the welded steel pipe of national standard DN250?
DN (nominal diameter) 250 is generally the industry said 273, welded steel pipe (spiral steel pipe) thickness is generally between 6-8mm, more common.
Q:What is the process of spiral steel tube production?
1. open panel inspection: after the steel plate is opened, the product line is entered, and the ultrasonic examination of the whole plate is carried out first.2., flat milling: through the anvil machine to make the original coiled steel flat, and then through the milling machine on the edge of the steel plate two sides milling, so as to achieve the required plate width, plate edge parallelism and groove shape.
Q:The outer circle of a seamless steel pipe 50 head into the outer circle of the 40 to close
Cold drawn steel tube and cold rolled steel pipe mill is a complete set of equipment which combines cold rolling, cold drawing, cold rolling and cold drawing to produce pipes. It is a unit for deep processing of hot-rolled pipes or welded pipes.
Q:Can seamless steel pipe and ordinary steel pipe be welded?
If your project is a seamless steel pipe, so theoretically, you put the tube with connected is not used.But the actual engineering operation, design drawings will be put on the normal need to improve the requirements of the drawings to the actual requirements, so if is the need of seamless steel pipe, welded pipe in the end so can you see yourself.
Q:How many meters per ton of steel tube?
Formula of steel tube: (outside diameter wall thickness) * wall thickness *0.02466= per meter weight1000 divided by the weight per metre is how many meters per ton
Q:Who knows what is the difference between double submerged arc welded pipe and longitudinal submerged arc welding?
Double submerged arc welding should be for spot welding and single side welding, they are straight line welds, but double submerged arc welding seam is more beautiful and fine.
