When the stainless steel fixed port is welded, it will be difficult to ventilate on both sides of the weld. At this time, how to ensure the argon filling protection on the inner side of the weld has become a difficult problem. For a long time, the reasonable price and perfect service of all kinds of stainless steel plates,Hato-Mayor-del-Rey5cr15mov stainless steel plate, stainless steel coils, stainless steel belts and stainless steel pipes have been recognized by the majority of customers. In the actual construction on site, we use two welding joints The above problems were successfully solved by plugging with water-soluble paper on the side, ventilation from the weld center and sealing with adhesive tape on the outside (see Table ).When using this process, the following key points should be paid attention to: during the welding process, the correct included angle between the welding handle, and the included angle between the welding wire and the weldment surface is & deg; & mdash; & deg;; correct the molten pool temperature, change the included angle between the welding handle and weldment, change the welding speed, etc. to change the molten pool temperature, so as to ensure Beautiful weld formation (uniform width,Hato-Mayor-del-ReyStainless steel pipe fittings, no concave, convex and other defects) During operation, the current shall be slightly larger than that of solid core welding wire, and the welding handle shall be slightly adjusted to accelerate the separation of molten iron and molten flux coating, so as to facilitate the observation of molten pool and penetration; when filling the welding wire, it shall be sent to places of molten pool and pressed inward slightly to ensure penetration and prevent concave; during welding, the welding wire shall be regularly sent and taken out, and the welding wire shall always be ensured Under the protection of argon to prevent the end of the welding wire from being oxidized and affect the welding quality; pay attention to the welding quality of the arc and arc stop, and the spot weld shall be polished to & deg; the slope shall be gentle, and pay attention to the defects such as arc pit and shrinkage hole during arc stop.Hato-Mayor-del-Rey,Check the clamping forming effect after each clamping, and there shall be no clamping in place or serious depression of pipe clamping. According to visual inspection, the pipe fitting end and the pipe are tightly bonded. The smaller the diameter of the diamond edge of the pipe fitting above DN is slightly smaller than the outer diameter of the pipe, ranging from .-mm. The larger the pipe diameter, the greater the difference.Production mode stainless steel pipe can be divided into seamless pipe and welded pipe according to the production mode. Seamless steel pipe can be divided into hot-rolled pipe, cold-rolled pipe cold drawn pipe and pipe. Cold drawing and cold rolling are the secondary processing of steel pipe; Welded pipe is divided into straight seam welded pipe and spiral welded pipe.Return,There shall be a special storage rack. The storage rack shall be a wooden or painted carbon steel support or padded with rubber pad to isolate it from carbon steel and other metal materials. During storage the storage position shall be convenient for lifting and absolutely isolated from other data storage areas. Protective measures shall be taken to avoid purification, collision with other components, purification and damage of iron metal. Series & mdash; martensitic precipitation hardening stainless steel pipe. Series & mdash; Martensitic precipitation hardening stainless steel.

Model & mdash; Commonly used precipitation hardening stainless steel model, usually also called -; %Cr,%Ni.Basic weight (density) / kg of steel plate: SPCC & mdash& mdash; Cold rolled carbon steel sheet and strip are generally used, which is equivalent to qa. The third letter C is the abbreviation of cold. When it is necessary to ensure the tensile test, add t at the end of the brand as spcct.Model & mdash; other properties are similar except that the risk of weld corrosion is reduced due to the addition of titanium.Product range,Duplex stainless steel product description: This stainless steel has good corrosion resistance in urea carbamate solution and high stress corrosion cracking resistance in chloride environment. At the same time, the duplex stainless steel has excellent mechanical properties and can be used in plant construction with high safety requirements.At present, the deformation energy is small. In low temperature environment, the phenomenon of reduced elongation and area shrinkage is called low temperature embrittlement. It is mostly produced on the body centered cubic structure of ferrite series.Quality assurance,Stainless steel pipes are divided into ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, stainless steel pipes bimetallic composite pipes, coated and coated pipes to save precious metals and meet special requirements. Stainless steel pipes have a wide variety, different uses, different technical requirements and different production. The outer diameter range of steel pipe currently produced is . & mdash; mm, wall thickness range . ~ mm. In order to distinguish its characteristics, we specialize in providing quality assurance for L stainless steel pipe,Hato-Mayor-del-ReyStainless steel pipe cleaning, s stainless steel pipe and L stainless steel pipe. During the preferential activities new and old customers are welcome to consult. Steel pipes are usually classified according to the following.: stainless steel plate: it can be divided into cold-rolled plate and hot-rolled plate. Its surface has bright surface, fog surface and matte surface. It is commonly known as stainless steel plate, including B plate and Ba plate. In addition, it can also be plated with other light colors according to customer requirements. The main specifications of plates are: m * m, m * m, m * m, m * M, m * m. If customer demand is large, we can cut them according to customer size. In addition, we can replace wire drawing plate, anti sliding plate and electroplating plateStainless steel pipes can be divided into CR series ( Series) Cr Ni series ( Series), Cr Mn Ni series ( Series) and precipitation hardening series ( Series). Series & mdash; Cr Ni Mn austenitic stainless steel series & mdash; Cr Ni austenitic stainless steel.Hato-Mayor-del-Rey,The surface resistance is less than mb; Wear protection; Scalable; Excellent chemical resistance; Good alkali metal and acid resistance; Strong toughness; Flame retardant.Stainless steel pipe is a kind of hollow long round steel, which is widely used in industrial transmission pipelines such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instruments and mechanical structural parts. In addition, when the bending and torsional strength are the same, s stainless steel pipe and L stainless steel pipe for a long time. It is an old brand of , with advantages in price and guaranteed quality It is also widely used in manufacturing mechanical parts and engineering structures. It is also commonly used as furniture, kitchenware, etc.;- Ferromagnetism due to m transformation shall be considered in use (such as in instrument parts).
