Features of Hot dip Galvanized Seamless Steel Pipe

 Hot-dip galvanizing is a process in which a metal material or part with a clean surface is immersed in a molten zinc solution, and a layer of metal zinc is formed on the surface through a physical and chemical reaction at the interface. Hot-dip galvanizing, also known as hot-dip galvanizing and hot-dip galvanizing, is an effective metal anti-corrosion method, which is mainly used for surface anti-corrosion of metal structures, facilities and materials in various industries. So what are the characteristics of hot-dip galvanized seamless steel pipe? 1. The gray patches of different sizes on the surface of galvanized seamless steel pipe are the color difference of galvanizing, which is a difficult problem in the current galvanizing industry, mainly related to the trace elements contained in the steel pipe itself and the components in the zinc bath. The stain does not affect the anti-corrosion performance of the steel pipe, only the difference in appearance. 2. There are gradually obv...

How to control internal surface defects of anticorrosive steel pipe?

 The scarring defect in the anti-corrosion steel pipe is the pit on the inner surface of the steel pipe, which is similar to the size of a soybean grain. Most of the scarring has gray-brown or gray-black foreign bodies. The influencing factors of internal scarring are: deoxidizer, injection process, smooth mandrel and other factors. Let’s take a look at how to control the inner surface defects of anti-corrosion steel pipes with anti-corrosion steel pipe manufacturers: 1. Deoxidizer The oxide is required to be in molten form when the mandrel is pre-pierced. Its strength and other strict requirements. 1) The particle size of the deoxidizer powder is usually controlled at 16 mesh. 2) The content of sodium stearate in the deoxidizer should reach more than 12%, so that it can be fully incinerated in the inner cavity of the capillary. 3) Determine the injection volume of the deoxidizer according to the inner surface area of the capillary tube, usually 1.5-2.0g/dm2, and the deoxidant dose...

A Brief Introduction to Xinyue’s LSAW Steel Pipe Production Base

 Xinyue LSAW steel pipe production base is located in Hebei, equipped with 3 JCOE double submerged-arc longitudinal welded production line and several roller welding production line, with a team of 328 workers, 58 senior engineers and technicians; Annual production capacity can reach 300,000 tons. The LSAW production line has introduced with supreme quality-guarantee technique -- JCOE, can produce longitudinal submerged-arc welded steel pipe from outer diameter 355.6mm to 1828.8mm (14” - 72”), wall thickness from 8mm to 60mm under various standards like GB/T9711, GB 50205, API SPEC 5L, API 2B, EN 10210, EN 10219, EN 10208, ASTM A53, ASTM A252, ASTM A500, and etc. The roller welding line can produce straight seam roller pipe from diameter 355.6mm to 3800mm, wall thickness from 8mm to 120mm. Installed with first-class laboratory of chemical composition analysis, metallurgical analysis, mechanical property and welding performance test, Xinyue can perform full set of experiments of raw...

briefly describe constant pressure gun operation

 The constant flow variable gun position operation is to keep the oxygen supply flow constant during the blowing process of a furnace steel, and to control the blowing by changing the position of the gun to change the interaction between the oxygen flow and the molten pool. Most manufacturers in China use a staged constant flow variable gun position operation. Oxygen lance operation is not exactly the same due to differences in converter tonnage, nozzle structure, raw material conditions, and steel grades. There are currently two lance operation modes. 1 high-low-high-low gun position mode. The open blow gun position is higher, and the initial slag is formed early. When the second batch of rice is added, the gun is lowered at the appropriate time. When the medium-term slag is returned to the dry, the gun can be added or an appropriate amount of flux can be added to adjust the slag fluidity to shorten the blowing time and the end point. Pull carbon out of steel. 2 High-low-low gun p...

Characteristics of Seamless Stainless Steel Pipe

 Seamless stainless steel pipe is actually a hollow cross section and both sides of the expansion of the resistance to air, steam, water and other weak corrosive media and acid, alkali, salt and other chemical corrosion medium corrosion of steel pipe. Also known as acid-resistant stainless steel. Stainless steel pipe suppliers are reputable to protect the environment from hygienic, cheap, and also thinner tubes as well as new, reliable, and effective ways to improve a simple and convenient connection, resulting in more irreplaceable benefits. There will be more and more engineering use, is more and more and prospects. Features of seamless stainless steel pipe: First, the thicker the wall thickness of the solution, it is really more cost effective and wise, the thinner the wall thickness, and its processing costs will appreciate sharply; Second, from the process of the product determines its limitations, from the general seamless steel pipe with low accuracy: wall thickness uneven, ...

Does slag oxidation have an impact on the smelting process?

 1 affecting dephosphorization and desulfurization, is conducive to dephosphorization, is not conducive to desulfurization. 2 affects the melting speed of lime. 3 affect the residual manganese content of steel grades. 4 affects the oxygen content at the end of the molten steel. 5 affect the yield of metals and ferroalloys. 6 affect the formation of foam slag and the occurrence of splashing. 7 affects the life of the converter lining. http://www.tjxysteel.com/news/Does-slag-oxidation-impact-smelting-process-586.html

How To continue to cooperate If Purchaser Are New One

 Tianjin Xinyue Industry and Trade Co., Ltd are exporting steel products. It is also common for some projects to follow up for one or two years. It is also common to change purchase managers for old customers. In the past, the cooperation with Tianjin Xinyue Industry and Trade Co., Ltd. did not mean that the new buyer would continue this relationship. Frankly, he must have his own old supplier, why should he insist on placing an order for you? Is there anything special reason with it? If not, it is reasonable to replace the others with a reliable supplier he trust. Therefore, when a new purchasing manager takes office, it is often the case that those projects will be re-released for sourcing and the suppliers will be re-cleaned. So many issues are not so simple on the surface. It may be really simple or complicated, but these are not visible on the surface. How do you deal with such things? The following is my personal experience. Firstly, make concessions, Both payment methods and...
