DISTINCTIVES FEATURES

A) The External surface is shot-blasted (Sa 2 1/2) by removing millscale and rust, obtaining metal surface to facilities the adhesion.
B) The pipe is heated in a electric or gas oven at a controlled temperature.
C) The adhesive is then applied by hot meit or copolymer. It binds the polythylene to the steel.
D) Immediately afterwards, the extruded polyethylene/polyprophylene is coated on the pipe.
E) After application of the polyethylene/polyprophylene, the pipe is coated by spraying water.

Q:Hot galvanized steel pipe for use?
The use of hot galvanized steel pipe: mainly used for the delivery of gas, heating.In the greenhouse gas, heating, with the kind of pipe and galvanized pipe, galvanized pipe as a water pipe, produced a lot of rust in the tube, the outflow of water not only pollute the sanitary ware, and mixed with smooth inner wall corrosion caused by bacteria, heavy metal content in the water is too high, serious harm to human health. In 60s and 70s, developed countries began to develop new types of pipes, and galvanized pipes were banned. China's Ministry of construction and other four ministries have also issued a civilization, from two, 000 years since the prohibition of galvanized pipe, the current New District cold water pipe has rarely used galvanized pipe, and some of the hot water pipe is galvanized pipe.
Q:What is the difference between the stainless steel pipe welded pipe and seamless pipe?
Grain size: usually, the grain size of the metal is related to the heat treatment temperature and the time at which the metal is kept at the same temperature. Therefore, the welded pipe and seamless tube annealing of the same grain size. If the minimum tube cold treatment, the grain size of the weld metal is smaller than the grain size, welding or grain size is the same.Strength: the strength of the pipeline in the composition of the alloy and alloy containing the same and the same heat treatment of seamless tube and seamed tube essentially consistent strength. After the tensile test and three-dimensional vibration test, tube tearing almost all occurred in the welding point or away from the heated area where. This is because there is little impurity in the weld and the nitrogen content is slightly higher, so the strength of the welded joint is better than that of other parts. However, the ASME Boiler and Pressure Vessel Association believes that the seamed tube can withstand 85% of the allowable pressure, which is mainly due to improved welding equipment data collection prior to today. The provisions of ASME 100% completely under license by ultrasonic testing pressure tube. Similarly, Europe and Asia also stipulates that can ensure the quality of welding performance by eddy current test tube, the eddy current testing is subject to legal procedures and licensed institutions. Trent's eddy current test was approved by the Swedish power division. ASME believes the current loss is relatively small, high-quality performance based on the seamed tube.
Q:What is the weight of hot galvanized steel tubes? DN150 4mm wall thickness
DN150 4mm wall thickness welded steel pipe theoretical weight is 16.21kg/m, galvanized steel pipe should be multiplied by the weight coefficient after galvanizing, C, DN150, wall thickness of 4mm, C=1.032, DN150, theoretical weight and wall thickness of 4mm galvanized steel is 1.02*16.21=16.7287kg/m = 16.73kg/m.
Q:Seamless steel pipe 8162 and 8163 what is the difference?
GB 8162 is the structure of the tube, there is no need for flaw detection, the use of mechanical processing, stents;
Q:Can galvanized steel tubes simmer?
Galvanized steel pipe can simmer bending.Is a set of bending bending bending die, no matter what kind of equipment, most are used in pipe, mainly used for oil and gas, infusion, more plays an important role in aircraft and engine.
Q:What does seamless steel tube mean? What are the main uses? What are the classifications?
The production process of seamless steel tube in general can be divided into two kinds of hot rolling and cold drawing, cold-rolled seamless steel pipe production process than hot-rolled billet to complex, first to three roller rolling and extrusion to sizing test, if the tube through the cutting machine cutting surface without crack growth response after cutting blank about one meter. Then enter the annealing process, annealing and pickling to use acid pickling liquid, should pay attention to the surface if there are a lot of bubbling, if there are a large number of bubbling pipe shows that the quality is not up to the standard. The appearance of cold rolling seamless steel tube shorter than hot-rolled seamless steel pipe, cold rolled seamless steel pipe wall thickness is generally higher than hot-rolled seamless steel pipe to be small, but the surface looks better than thick wall seamless steel pipe is more bright, rough surface is not too much, not too much burr diameter.
Q:Seamed steel pipe seamless steel pipe, carbon steel pipe, galvanized pipe, four how to distinguish between
Welded and seamless steel pipe is divided according to the processing form, usually welded seam steel tube, seamless steel tube drawing and hot two ways, carbon steel is material, galvanized pipe is welded pipe production after the surface is galvanized
Q:How to make the magnetic steel, can be like a magnet?
Magnetization. Winding the insulated wire on the object, passing in the direct current, and taking it down after a period of time.
Q:Where is a steel pipe casing usually used?
Classification of casing: rigid casing, flexible waterproof sleeve, steel pipe sleeve and iron sheet bushing, etc..
Q:Are there specifications for scaffold steel pipe with 48mm * 3.2mm?
Scaffold tubes are our name for materials used to build scaffolding, because most scaffolding uses tubular bamboo or steel tubing. Bamboo and other bamboo is for a long time in the use of the scaffolding tube, but due to lack of safety and durability, now only in rural and urban area construction is lagging behind some of the home building small building has been used. The modernization construction, the most commonly used type of scaffolding pipe is steel pipe, the scaffolding should not only meet the demand of workers, but also to meet the characteristics of scaffolding firm and durable, so tough hard steel is the best choice. The selected steel pipe generally requires smooth surface, no cracks, no bending, no rust, and meet the relevant national standards.
