Q:What is the outer diameter and wall thickness of DN40 steel pipe?
DN40 pipe diameter 48.3mm diameter, allowable deviation of plus or minus 0.5mm it depends on what you have, the outside diameter of 45, there are other dimensions, you can see the manual
Q:ASME seamless tube how to express, what is the form, I did not find on the ASME, thank God!
Welded and seamless pipe standards are ASME B31.10, no go, if you want to force a seamless tube, the request can be seamless for seamless meaning.In addition to that, the cost and difficulty of manufacturing welded pipe is higher than that of seamless tube.
Q:D108*4 what does "D108" mean by seamless steel tubes? What does "*4" mean?
Seamless steel pipe: a pipe with a hollow cross section, used as a conduit for transporting 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:How can two smooth steel pipes be joined? The size of the two pipe is different (except for welding)
Rectangular fastener: used for the connection of two vertical intersecting steel tubes. It relies on the frictional force between the fastener and the steel tube to carry the load.Swivel fastener: used for connecting two steel tubes intersecting at any angle
Q:Galvanized steel pipe in addition to good rust resistance, what are the advantages?
Galvanized steel is cracking for 39 days and will not, especially suitable for Northern very cold environment.
Q:When can I use the PVC pipe and when to use the galvanized pipe?
Galvanized pipes are generally used outside the drying environment or building blocks, and PVC is mainly used for pre embedding in walls or humid environments. If in the ceiling ceiling, below the roof, you need to use galvanized pipe, in the floor below, on the ground you need to use PVC.
Q:Is there any difference between HFW steel pipe and ERW steel pipe?
ERW steel is high frequency ERW pipe, English Electric Resistance Welding, referred to as the abbreviation of machined steel in diameter and wall thickness of the pipe size range, with greater flexibility, especially in production
Q:The plastic pipe and steel pipe difference
In the plastic coated galvanized steel pipe inside the plastic coated manufacturing method. The thickness of the internal plastic is thin, which is equal to a plastic skin.
Q:Does the seamless steel pipe need rust removal?
Spray (throw) shoot derusting by the high-power motor to drive the spray shot (impeller) blade rotating speed, the steel grit, steel shot, iron wire, minerals and other abrasive jet for 20# seamless steel tube surface under the action of centrifugal force (left) radiation treatment, not only can completely remove the dirt and rust, oxide, and the role of 20# seamless steel in abrasive blast and friction force, can achieve the required uniform roughness.Not only can the physical adsorption effect on the surface of the pipe be increased, but also the mechanical adhesion of the anticorrosive layer to the pipe surface can be enhanced. Therefore, spraying (throwing) shot derusting is an ideal method of rust prevention for pipeline corrosion protection. Generally speaking, shot peening (sand) derusting is mainly used in the inner surface treatment of tubes, shot blasting (sand) derusting is mainly used for the outer surface treatment of tubes.
Q:What is the process of spiral steel tube production?
X ray flaw detection: 100% X ray industrial television inspection of internal and external weld seams, and image processing system is adopted to ensure the sensitivity of flaw detection.8. press test: the steel pipe is tested by root test on the water pressure test machine to ensure the test pressure of the steel pipe to meet the standard requirement.9. chamfering flat head: the qualified steel pipe is processed at the end of the pipe to achieve the required size of the end of the pipe10. final inspection: ultrasonic and X ray inspection, and magnetic particle inspection at the end of pipe to check for welding problems and pipe end defects.11., marking: qualified steel pipe for oil, in order to prevent corrosion, and according to user requirements for marking.
