Q:Water, gas, steel pipes, thick steel wire means?
Thick steel wire pipe is the same wire pipe, but the wire pipe is thin tube, easy to damage, so with thick as the outer diameter can protect the wire tube, so called thick steel wire pipe.
Q:D108*4 what does "D108" mean by seamless steel tubes? What does "*4" mean?
D108: refers to the outer diameter of 108mm;4: refers to the wall thickness of 4mm.
Q:What is the single length of galvanized steel pipe?
Hot dip galvanized steel pipe is widely used in fire, power and highway.
Q:What is the diameter of the steel tube DN20?
Pipe installation without conversion, because in the same standard in the same diameter connecting dimensions of the same nominal pressure level of the same, and the same material have the same diameter, the nominal diameter of the purpose is to facilitate connectivity
Q:Why can't stainless steel be put together with carbon steel tube?
The bimetallic corrosion is terminated only when one of the three conditions is changed. Galvanic corrosion is related to the contact area of bimetal and the greater the contact area. Corrosion is less. The driving force of galvanic corrosion is the potential difference.[galvanic corrosion] refers to two or more than two kinds of electrode potential of metal in the corrosive medium, and contact with each other caused by electrochemical corrosion, also known as contact corrosion or double metal corrosion.
Q:What time what time for gas pipeline steel pipe PE pipe
PE pipe must be installed underground, the steel tube can be exposed, when not all PE pipe for pipe laying, overhead installation. But the steel tube is easy to rust, so it can be used where the basic use of PE pipe buried PE pipe.There are galvanized steel pipe and seamless steel pipe, galvanized pipe can only be used for low-pressure homes
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: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: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.
Q:What is the process of spiral steel tube production?
Visual inspection: some basic parameters are checked by professional technicians.6. ultrasonic inspection: 100% inspection of inner and outer weld seam and parent material on both sides of weld seam.
