  • Precision Seamless Steel Pipe
    Precision Seamless Steel Pipe is a kind of high precision steel pipe material after quenching or cold rolling treatment. Because of no oxide layer of the surface, precision seamless steel pipe has the advantages of high-pressure, high precision. high grade finish, which can be used to manufature cylinders and welded pipes. Compared to other solid steel material, seamless steel pipe is lighter with the same flexural torsional strength. It is an economic section of steel, widely used in the manufacture of structural and machanical parts. Precision seamless steel pipe also has some of their own characteristics. They have been widely used to manufacture ring parts can improve the utilization of materials, simplify the manufacturing process, save materials and processing time, such as rolling bearing rings, jack sets. Generally, the industry require a higher precision, they often use precision seamless steel pipe , others mainly use seamless steel pipe if there is no precision requirements. After all, the price of precision seamless steel pipe is higher. Why the current price of precision seamless steel pipe will be improved? China's steel production has increased, but the market demand for steel is too large, resulting in steel demand. And steel is the main material for the production of precision seamless steel pipe , steel shortage led to the shortage of precision seamless steel pipe, we know that the market demand for precision seamless steel pipe is increasing, and in this case, the price also increased. There are manydifferent types of precision seamless steel pipe. The materials are also different, such as 10#, 20#, 35#, 45#, 16Mn, 20Cr, Gcr15 and so on. Different types are required, therefore, there will be a type of precision pipe inevitably tube out of storage in a specific period of time, which makes the price increase. From a certain point of view, if the market supply of precision seamless steel pipe can meet the actual market demand, then the price will not be high. With the mature of precision pipe industry, the quality also need improve and become much more strict, many enterprises have to improve the production process and production technology. This is an increase in the production cost of the pipes. Therefore, the increase of added value leads to higher price.

  • LSAW Steel Pipe Manufacturing Process
    LSAW (longitudinal double submerge are welding) carbon steel pipe is a type of saw pipe made of steel plates that were hot rolled by JCOE or UOE forming technology. JCOE technology represents the shaping and forming processes invoived during manufacturing as well as the inner and outer welding and cold expansion carried out after welding. The LSAW targe diameter steel pipe manufacturing process is explained in the steps below: 1. Plate Probe: This is used for manufacturing the large diameter LSAW joints right right after it enters the production line which is the initial full- board ultrasonic testing. 2. Milling: The machine used for milling does this operation through two-edged milling plate to meet the requirements of the plate width and the sides parallel to the shape and degree. 3. Pre-curved side: This side achived by using a pre-bending machine on the pre-bending plate edge. The plate rdge needs to meet curvature requirement. 4. Forming: After the pre-bending step, in the first half of the JCO molding machine, after stampted steel, it is pressed into a "J" shape while the on the other half of the same steel plate it is bent and pressed into a "C" shape, then the final opening forms an "O" shape. 5. Pre-welding; This is to make a welded pipe steel a straight seam after it has been formed and then use gas welding seam(MAG) for continuous welding. 6. Inside welding: This is done with a tandem multi-wire submerged arc welding (about four wire) on the inner part of the straight seam welded steel pipe 7. Outside weld: Outside weld is the tandem multi-wire submerged arc welding on the outer part of the LSAW steel pipe welding. 8. Ultrasonic Testing: Outside and inside of the straight seam welding steel pipe and both sides of the base material are welded with 100% inspection. 9. X-ray inspection: X-ray industrial TV inspection is carried out on the inside and outside using image processing systermto make sure there is detection sensitivity. 10. Expansion: This is for accomplishing submerged arc welding and straight seam steel pipe length hole diameter so as to improve the steel tube's size precision and improve the distribution of stress in the steel pipe. 11. Hydraulic test: This is carried out on the hydraulic test machine for steel after expanding by-root test for ensuring the steel pipe meets the standard requirements with the machine having an automatic recording and storage capabilities. 12. Chamfering: This involves the inspectipn carried out on the steel pipeat the end of the whole process.

  • Differences Between ERW Steel Pipe and HFW Steel Pipe
    The didderence of ERW, HFW welding processes. ERW welding process refers the heat generated by the resistance to current flowthat pass through the jointed metals. So a large current is needed to electrify the whole surface of the steel plate or coil to the length of welding. In the ERW welding process, the electric current that pass through the entire conductor is at 50/60 Hz. HFW welding process is not the same case with the high-frequency process, since it is only a section of the steel metals is heated by the induction of electric coil. High-frequency is generated by either AC or DC current. In these cases, the constant current welding generator and constant voltage high-frequency welding generator are used. Constant current welding machine generates power in 100-800 kHz. In the elder processes, the conversion of 60 Hz. AC current to HF was done by using triode and tank circuits. New welding machine usesmetal oxide silicon, filed-effect transistors, usually associated with parallel resonant circult. The constant voltage version generators use insulated gate bipolar transistors designed to power about 2000 kW with frequency rages of 100-600 KHz. HFW is required in API 5L PSL2 ERW steel pipe According the API 5L and ISO 3183 specification, for PSL2 pipes in welded process the HFW welding is a mandatory requirements for ERW steel pipes. As it is an improvement from the inherent problem of hardness, lack of fusion and susceptibility of stress corrosion cracking(SCC) ERW steel pipe includes HFW steel pipe ERW is general designation of resistance welded steel pipes. It can be sorted into two types: alternated current welding(AC) and direct current welding(DC). According to different frequency, AC welding can be divided into low frequency welding intermediate frequency welding, ultra frequency welding and high frequency welding. The high frequency welding (HFW) is mainly used in ordinary or thin wall steel pipe. It includes contact welding and induction welding. Directcurrent welding is generally used for small caliber steel tubes in general, HFW is one of ERW production methods, it adopts the high frequency welding process. So ERW includes HFW steel pipe.

  • The Features of Alloy Steel Pipe
    Alloy steel pipe is a kind of steel pipe which is named according to its material - alloy steel. It is made by using alloy steal. Just like the origin of the name of weld carbon steel pipe.It is named according to the manufacturingtechnique of steel pipe. And there are two kinds of steel pipe, one is the welded steel pipe, and the other is the seamless steel pipe. Made by superior carbon steel, structural steel and stainless heat resistantsteel, alloy steel pipeis formed by hot rolling or cold rolling. And due to the materialof alloy steel pipe, it has superior alloy steel pipe features. It can work under the high temperature, high pressure. And it can even endure sulfur attacks, organ acid corrosion. Due to the superior alloy steel pipe features, alloy steel pipe is widely used in making the high temperature super heater, reheated and high pressure boiler in electric plant, nuclear powerindustry. Apart from those alloy steel pipe featuresmentioned above, it also has other obvious alloy steel pipe features. The weight of the alloy steel pipeis extremely light, whicheasy to transport and carry. Moreover, it has the same torsional strength as well as flexure strength as solid steel plant. It is economic and it quite saves the cost,which is welcomed by people. According to the different shapes of cross sectional area, alloy steel pipe is divided into circular pipe and special pipe. And under the conditionof the same perimeter, the area of a circle is the biggest, so we can convey more fluid by using circle pipes. In addition, when the annulus cross section bears the external radial pressure or internal radial pressure , the stress of the circle pipe is fairy equal, so most of alloy steel pipes arecircular pipes. The most important features of alloy steel pipe is that the alloy steek pipe can be recycled 100% so that it iscompletely accord with the national strategy including environment protection, material saving, and environmental friendly.

  • The Difference Between Hot-dip Galvanizing and Cold Galvanized
    Hot-dip galvanizing and cold galvanized the difference: 1. Galvanizing, also known as hot dip galvanized, he is the ingot melted at high temperatures, a number of supplementary material in place, then dipped galvanized metal structure slot, the metal component on a layer of zinc coating . The advantages of hot-dip galvanizing corrosion of his ability, adhesion and hardness of zinc coating is better [Cold plated" or [plating", ie the zinc salt solution by electrolysis, to the plating on the coating, generally do not have heating, small amount of zinc, the wet environment is very easy to fall off. 2. Hot dip galvanized (galvanizing) Hot-dip galvanizing is a chemical treatment, is the electrochemical reaction. Cold galvanizing is the physical address, just brush the surface layer of zinc, the zinc layer is easy to fall off. Construction in the use of hot dip galvanizing. Continuous hot dip galvanizing process: steel → heating → cooling to the temperature galvanized galvanized → cooling → Cold galvanized zinc is only 10-50g/m2, its own corrosion resistance than hot dip galvanized a lot of difference. Galvanized by a relatively cheaper price. Hot dip galvanized steel body is hot dip galvanized surface under the condition of its adhesion strong, not easy to fall off, although there hot dip galvanized pipe corrosion phenomenon, but in a very long period to meet technical, health requirements. 3. Technological differences First of all, is the difference between process: hot-dip galvanizing is the workpiece degreasing, pickling, dipping, drying liquid immersion in molten zinc certain period of time, can be raised. Also known as electro-galvanized cold galvanizing, is to use electrolysis devices work piece through the degreasing, pickling ingredients post into the zinc salt solution, and connect the anode electrolysis equipment; in place across parts of zinc plate connected to the electrolysis equipment positive, power on, use of current from the cathode to the anode of the directional movement of the workpiece will be deposited in a layer of zinc. Zinc finished the difference: no cold galvanized hot-dip galvanizing delicate bright appearance, but the thickness of zinc coating of cold galvanizing aspects of hot-dip galvanizing is a few times. Galvanized corrosion resistance is also several times. 4. Environmental issues Fewer emissions of some hot-dip galvanizing. Galvanized pollutants are mainly artifacts of waste acid pickling. Cold galvanized pollutants include parts of the waste acid pickling, electroplating waste, liquid waste such as passivation. Cold galvanized the type and quantity of pollutants discharged are much more than hot dip galvanizing. Hot-dip zinc standards: GB/T13912-92 Hot dip galvanizing: hot dip galvanizing process is generally completed after Hemming, when the load is not less than 5mm thick flat steel, the galvanized zinc coating after the average weight of not less than 610 grams / square meter; when the load flat steel thickness less than 5mm, the galvanized zinc coating after the average weight of not less than 460 grams / square meter, and after galvanizing quality requirements should be consistent with the provisions GB/T13912
