In order to ensure the appearance quality of continuous casting slab, select appropriate maintenance slag; During continuous casting, the vibration marks formed on the surface of continuous casting slab due to the vibration of mold shall be; Electromagnetic stirring must be used in continuous casting of ferritic stainless steel pipe fittings.Stainless steel pipe packing bag is nothing more than the function of protecting the surface of stainless steel pipe, so most stainless steel pipe users do not have to question this point.Appeldoren,Seamless steel pipe): round billet & rarr; Heating → Perforation & rarr; Three roll cross rolling, continuous rolling or → Off pipe & rarr; Sizing (or reducing) → Cooling → Straightening & rarr; Hydrostatic test (or flaw detection) → Mark & rarr; The raw material for warehousing and rolling seamless pipe is round pipe blank. The round pipe blank shall be cut and processed by cutting machine, and the blank with a growth of about m shall be brought to the furnace for heating. The billet is sent to the furnace for heating at a temperature of about degrees Celsius. The fuel is hydrogen or acetylene. The temperature in the furnace is the key problem. After the round tube billet is discharged from the furnace, it should be pierced through the pressure piercer. Generally, the more common piercer is the cone roll piercer. This piercer has high production efficiency and good product quality. It is specialized in stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe, with high pressure resistance grade,Appeldoren304 stainless steel sanitary pipe, good waterproof performance, fire and high temperature resistance, strong overload capacity corrosion resistance, radiation protection, long service life, large perforation diameter expansion, and can wear a variety of steel grades. After perforation, the round tube blank is successively rolled by three roll cross rolling, continuous rolling or rolling. Take off the pipe after sizing. The conical drill bit of the sizing machine rotates into the steel embryo at high speed to form a steel pipe. The inner diameter of the steel pipe is determined by the outer diameter length of the sizing machine bit. After sizing, the steel pipe enters the cooling tower for water spray cooling. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydrostatic test) for internal flaw detection. If there are cracks, bubbles and other problems inside the steel pipe, they will be detected. Steel pipes should be strictly selected manually after quality inspection. After the steel pipe is inspected, specification, production batch number, etc. shall be sprayed with paint. And hoisted into the warehouse by crane.The surface resistance is less than mb; Wear protection; Scalable; Excellent chemical resistance; Good alkali metal and acid resistance; Strong toughness; Flame retardant.Libyan Arab Jamahiriya ,Austenitic stainless steel can be used to manufacture stainless spring, clock spring and steel wire rope in aviation structure after deformation strengthening. If welding is required after deformation, spot welding process and deformation can only be used to increase the tendency of stress corrosionStainless steel pipes and water transmission equipment for fluid transportation such as water and gas are advanced basic water purification materials in the world. They have strong anti-corrosion performance, which can not be compared with cast iron pipes carbon steel pipes and plastic pipes.Crimping: during crimping, and the jaw is perpendicular to the pipe axis.

Inspection: after crimping the convex part of the pipe fitting is placed in the concave groove of the die,AppeldorenStainless steel handrail pipe, check the crimping size with a special gauge.  — Cheap model (British and American),Appeldoren318 stainless steel plate, usually used as automobile exhaust pipe, is ferritic stainless steel (chromium steel).There are mechanical, chemical and electrochemical methods to remove the scale of stainless steel pipe. Due to the complexity of the composition of the scale of stainless steel pipe it is not easy to remove the scale on the surface and make the surface highly clear and flat. Generally, the removal of the scale of stainless steel pipe should be carried out in two steps,Stainless steel pipe, which was produced and used in China at the end of the s, is a new family emerging in the field of pipe materials. It has been widely used in building water supply and direct drinking water pipelines.Model & mdash; Commonly used precipitation hardening stainless steel model, usually also called -; %Cr%Ni.Stainless steel pipes are divided into ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing 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, 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.

All steel with openings at both ends and hollow sections, and with a large ratio of length to section perimeter, it can be called pipe section or tubular fittings, which belong to the category of pipe products.average method,Pipeline direct drinking water has developed rapidly. With the development of national economy, pipeline direct drinking water has developed rapidly in domestic cities such as Beijing, Shenzhen, Shanghai and Chongqing, and economically developed medium-sized cities have also actively planned to catch up. In direct drinking water, stainless steel pipe system is undoubtedly second to none. At present, domestic high-grade hotels and public places have been equipped or are equipped with direct drinking water pipes.At this time, we usually answer directly: no! What we produce is stainless steel decorative pipe, which belongs to stainless steel slotted pipe. It can not be used as stainless steel water pipe. If you want to choose stainless steel water pipe, you must choose stainless steel pipe.Low temperature embrittlement of stainless steel pipe --- in low temperature environment, the deformation energy is small. In low temperature environment,Crimping: during crimping, and the jaw is perpendicular to the pipe axis.Stress corrosion cracking (SCC) refers to the cracking caused by the combined action of stress corrosion stress (mainly tensile stress) and corrosion of austenitic stainless steel Austenitic stainless steel is prone to stress corrosion in corrosive media containing chloride ions. When the Ni content reaches % - %, it is a long-term enterprise engaged in stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe. Welcome to consult. The stress corrosion tendency of austenitic stainless steel is very large. Continue to increase the Ni content to ~ %, and the stress corrosion tendency gradually decreases until it disappears.Austenitic stainless steel. It contains more than % chromium, about % nickel and a small amount of molybdenum, titanium, nitrogen and other elements. Good comprehensive performance and resistance to corrosion of various media.
