Production Process

Oxygen lance pipe for fluid transportation: it is used as a pipe for transporting fluids to transport oil, natural gas, gas, water and certain solid materials. Structural oxygen lance pipe: used for general structure and mechanical structure. Precision inner diameter oxygen lance pipes for hydraulic and pneumatic cylinders: used to make hydraulic equipment used in coal mines, hydraulic cylinders and plungers for truck cranes, etc. Oxygen lance pipes for petroleum cracking: Oxygen blowing pipes for furnace pipes, heat exchanger pipes and pipelines in petroleum and refineries. No matter which industry needs to use the oxygen lance pipe, it must have very high requirements on the output quality, and some of the requirements are very strict.

Main Differences Of Oxygen Gun Tube Products

There are two main differences between oxygenlance pipe products, one is the material, and the other is the implementation standard. The specifications and materials are the same, but the implementation standards are very different. Oxygen lance pipe has the advantages of heat resistance, oxidation resistance, vulcanization resistance and corrosion resistance, which makes it more and more popular in the application field. When we buy oxygen lance tubes, we always pay attention to price, quality and characteristics. High cost performance ratio directly determines the good use experience of customers. 1. High quality of oxygen lance pipe: all production links from raw material selection to finished product production are under strict quality control and management. A number of high-tech personnel ensure the product inspection standard rate; Adopt domestic advanced high-frequency welding technology to ensure product quality; Advanced technology, excellent equipment, strong technical force and complete quality inspection; 2. Low consumption of oxygen lance pipe: high temperature resistant coating can produce strong heat resistance and oxidation resistance, greatly reduce the consumption of oxygen blowing pipe and reduce the cost. Strong productivity, sufficient inventory and timely delivery. 3. Low price of oxygen lance pipe: the production line formed by more advanced production equipment realizes a high-quality, low-cost and perfect guarantee system, so that you can rest assured before, during and after sales.

Products Advantage

Oxygen lance pipe can provide enough oxygen for steel smelting and other industries. In the process of use, in order to resist corrosion and improve the service life of the equipment, a layer of aluminum products with good stability is usually brushed on the surface of the commodity, that is, the so-called aluminizing treatment. As a heat treatment method for steel-making oxygen lance pipe, it is characterized by aluminizing diffusion annealing in addition to conventional degreasing, pickling, washing, plating aid, drying and hot dip of molten aluminum, so as to achieve the aluminizing layer thickness of more than 0.2mm, then test gas, silk and phosphoric acid washing, and then coating and porcelain. The coating has a special secret prescription. The heat resistance and corrosion resistance of the aluminum penetration coating in the treatment process are greatly improved. The coating is firm and not easy to fall off, which effectively improves its service life, saves steel, saves pipe replacement time, improves oxygen blowing efficiency, and reduces labor intensity of workers. In addition, the coating materials of the fireproof thick wall oxygen lance pipe are micro silica powder, quartz powder, high alumina cement, fireproof powder and magnesium oxide powder, which are mixed with sodium silicate and toluene in proportion to form a paste. The alcohol can be applied on the metal pipe for 10 minutes, and then the metal pipe is put into a dry room at about 60 ° C. It must be a fireproof commodity. Compared with the prior art, the thick wall made after coating on the metal pipe has a longer service life, reduces the consumption of the metal pipe, reduces the smelting time, and is simple to make. The metal pipe can be successfully coated only once.
