　　Steel companies will implement production restrictions again, from 0:00 on October 10, 2016 to 24:00 on October 20, 2016. From YTYSQTGD, it can be seen that the increase in environmental governance efforts and the increase in maintenance by Tianjin spiral pipe manufacturers will to some extent alleviate market supply pressure. At that time, as terminal demand returns to normal, domestic steel market inventory is expected to return to the downward trend. Cangzhou Quantong Pipeline Co., Ltd., a manufacturer of spiral steel pipes in Taiwan, has once again been awarded the "Contract abiding and Creditworthy Enterprise" certificate by the Industry and Commerce Bureau. Since its establishment in 2008, the company has received this certificate for several consecutive years. Corporate credit is not only the life of enterprises, but also the foundation of social credit construction. Only by truly establishing the integrity concept of "abiding by contracts and valuing credit" can a company establish a stable foothold in the increasingly open and competitive global market economy. The company focuses on the production and processing of spiral steel pipes. Over the years of development, we have attached great importance to the construction of corporate credit and have always adhered to the principles of honesty and integrity. Therefore, smaller diameter welded pipes mostly use straight seam welding, while larger diameter welded pipes mostly use spiral welding. Double wire automatic welding is an advanced welding technology developed in recent years. In addition to its semi-automatic single wire welding characteristics, it also has welding characteristics such as energy concentration and high deposition efficiency. The wall thickness standard and manufacturing method of spiral steel pipes: The steel pipes within the scope of this standard use hot-rolled steel strips as pipe blanks. Double sided submerged arc welded pipes used for pressurized fluid transportation should have a certain channel between the stacks of double-sided submerged arc welded pipes. The width of the inspection channel is generally around 0.5m, and the width of the access channel depends on the size of the material and the transportation machinery, generally ranging from 1.5 to 2m. During the forming process, the steel plate deforms uniformly, residual stress is small, and the surface does not produce scratches. Good plasticity, easy to weld and process into shapes; Spiral seam submerged arc welded steel pipes for general low-pressure fluid transportation are made using double-sided automatic submerged arc welding or single-sided welding methods, and are used for water, gas, air, steam, and other general low-pressure fluid transportation submerged arc welded steel pipes. Their strength is generally higher than that of straight seam welded pipes, and they can produce welded pipes with larger diameters using narrower billets.

　　This can improve the phenomenon of decarbonization. The media that cause decarburization on the surface of the spiral tube are mainly oxidizing gases such as oxygen, water vapor, and carbon dioxide. When these gases come into contact with the heated spiral tube, they will cause oxidation and decarburization of the spiral tube. Therefore, controlling the ratio of carbon dioxide and carbon monoxide in the furnace is also very important. In fact, adding protective gas nitrogen into the spiral tube forging furnace is also very effective. Nitrogen can disperse certain oxidizing gases and reduce the decarburization phenomenon of the spiral tube. The prices of bulk raw materials such as strip steel have also risen significantly. At the same time, the domestic market as a whole presents a situation of oversupply of spiral steel pipes. The price of spiral steel pipes has not shown significant improvement, and the price of spiral steel pipes has only increased by less than 5% compared to the beginning of the year. The high cost of spiral steel pipe squeezing has continued to cause a significant decline in enterprise efficiency, and the main sales profit margin of spiral steel pipes in the steel pipe industry is estimated to be only around 1%. The nominal diameter is different from the actual diameter, and according to regulations, there are two types of wall thicknesses: ordinary steel pipes and thickened steel pipes. Among them, α is the helix angle of the spiral welded pipe weld, and the range of large-diameter spiral steel pipes. Spiral steel pipes are made of strip steel coils as raw materials, often formed by warm extrusion, and welded by automatic double wire double-sided submerged arc welding technology. Large caliber spiral steel pipes are a general term, generally referring to spiral steel pipes with a diameter greater than 1 meter. And make the two ends of the weld flush. Spiral welded pipes are produced by spiral forming raw steel strips through a forming machine and using internal and external submerged arc welding to produce spiral welded pipes of different specifications. The production process of double-sided submerged arc spiral welded steel pipes is simple, and the operating cost is low for large and medium diameter welded pipes. It has the advantage of low-cost operation and is suitable for medium and large diameter low-pressure water pipes. Our company is a large spiral steel pipe manufacturer in Hebei Province. Our factory produces a complete range of spiral steel pipes, including spiral steel pipes for water plants, sewage discharge, tap water, buried water transmission, and pile driving, , Q235B spiral steel Q345B spiral pipe, Q345B spiral steel pipe, L290 spiral steel pipe, L360 spiral steel pipe.

　　Welded spiral steel pipe refers to a steel pipe with joints on its surface, which is formed by bending and deforming steel strips or plates into circular, square, or other shapes before welding According to different welding methods, it can be divided into arc welded pipes, high-frequency or low-frequency resistance welded pipes, gas welded pipes, furnace welded pipes, Bondi pipes, etc According to the shape of the weld seam, it can be divided into straight seam welded pipe and welded spiral steel pipe Electric welded steel pipes are used in industries such as petroleum drilling and machinery manufacturing Furnace welded pipes can be used as water and gas pipes, while large-diameter straight seam welded pipes are used for high-pressure oil and gas transportation; Welded spiral steel pipes are used for oil and gas transportation, pipe piles, bridge piers, etc Welded steel pipes have lower costs and higher production efficiency than seamless steel pipes The strength of welded spiral steel pipes is generally higher than that of straight seam welded pipes. It can produce welded pipes with larger diameters using narrower billets, and can also produce welded pipes with different diameters using billets of the same width However, compared to straight seam pipes of the same length, the weld seam length increases by 30~, and the production speed is lower Therefore, smaller diameter welded pipes mostly use straight seam welding, while large-diameter welded pipes mostly use spiral welding

　　To carry out lean management and promote cost reduction and efficiency improvement in enterprises, the third is to adjust product structure, accelerate the implementation of differentiation strategy, accelerate the development and cooperation of spiral steel pipes for industrial chain extension, and broaden the market space of spiral steel pipes for products. We produce large-diameter pressure steel plate coils with a wall thickness of 6mm to 100mm, as well as welded flanges with a diameter of Φ 400 to Φ 2000mm. We produce flange blind plates, elbows, tees, heads, reducers, bends, wear-resistant fittings, and other pipeline accessories made of stainless steel, carbon steel, and alloy steel materials. In addition, our company is engaged in the construction of pipe anti-corrosion engineering. Spiral welded pipes have different price specifications. We need the customer to provide the diameter and wall thickness of the steel pipe you need. Due to price instability, please refer to the inquiry on the same day. Some customers ask me about the price, and after quoting to them, they ask how much cheaper I can get. In fact, our quotes are very low because you have the sincerity to buy, we have the intention to sell, and we want to cooperate with you with sincerity. How can we quote you a higher price? Some customers still say that your price is so cheap, is your quality reliable? After I give you the deposit, won't you ship the goods to me? Or maybe the quality of the product you made for me is not good. This includes groove processing of welded parts, surface cleaning of the welded area, drying of flux, etc. Groove processing should ensure that there are no defects such as incomplete penetration at the root of the weld seam, and minimize the amount of filler metal as much as possible while meeting the requirements to save costs. Commonly used grooves include V-shaped, Y-shaped, X-shaped, double Y-shaped, and double U-shaped, etc., when the plate thickness is the same. Double sided groove consumes less filler metal than single-sided groove, and U-shaped groove consumes less welding deformation than V-shaped groove, especially with the increase of plate thickness. These advantages are more prominent. For steel pipes with larger wall thickness, X or double U-shaped grooves can be opened. The cleaning of the welded area mainly involves removing surface rust, oxide scale, oil stains, and moisture to prevent porosity. We have a long-term inventory of various specifications of seamless steel pipes, high-pressure boiler pipes, fluid pipes, structural pipes, fertilizer pipes, as well as alloy steel pipes imported from Germany, the United States, Japan, and Italy. We maintain a stock of about 10000 tons and have an annual sales volume of over 100 million yuan. All products sold comply with standards and are suitable for various fields such as engineering, coal mining, textiles, electricity, boilers, machinery, etc.
