Quezon1mm201 sProduction process of stainless steel welded pipe: raw materials -- strip splitting -- welded pipe making -- end repair -- polishing -- Inspection (spray printing) -- Packaging -- shipping (warehousing) (decorative welded pipe).
It can reduce a lot of raw materials of support frame and save labor and money.
Flourishing.Mode, load — Displacement curve and load — The effects of high temperature, wall thickness and length diameter ratio on the ultimate bearing capacity, stiffness and ductility of the specimens were analyzed. The results show that high temperature has no obvious effect on the failure mode of the specimen but it will reduce the ultimate bearing capacity of the specimen; After high temperature,
The production mode is divided into seamless pipe and welded pipe. Seamless steel pipe can be divided into hot rolled pipe, cold rolled pipe, cold drawn pipe and pipe, etc. 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.
.How to use stainless steel plate and plastic plate on one side of the kitchen board? Stainless steel is used for daily applications, such as cutting potato shreds and mincing meat. The plastic side is used to chop tubular bones and chicken nuggets. Because the plastic is not easy to crack and mold, sanitary and durable. For its maintenance, the development of China's stainless steel industry should constantly improve product quality, better develop overseas trade and deal with trade protectionism, and combine products with environmental protection, energy resources and human environment to improve
Increase at the same time. Because austenitic series stainless steel pipes have MS point (martensite start temperature or martensite formation temperature) at low temperature (subzreo temperature) martensite can be formed when it is kept below MS point. Martensite formation at low temperature makes austenite series stainless
Chlorine ion exists in the service environment. Chloride ions exist widely, such as salt, sweat, sea water, sea breeze, soil, floating rust of iron foam, etc. Stainless steel corrodes rapidly in the presence of chloride ions, even more than ordinary low carbon steel. So the use of stainless steel
Water, reduce transportation costs, reduce heat damage, and prevent environmental pollution of sanitary ware.
Under various natural ambient temperatures the pipeline compensator can be installed according to the larger installation length Lmax, and there is no need to stretch or shrink.
Quotation sheet.Stainless steel plate can be cut 20mm thick, and supports cutting A-type groove, V-type groove, Y-type groove, for a 20mm thick steel plate,FlourishingTISCO 316L stainless steel coil, if the beveling machine is used, the beveling of one side takes about 40-50 minutes,Flourishing410 stainless steel belt manufacturer, which consumes a lot of time and labor costs
The recrystallization temperature changes with the deformation variable. When the deformation variable is 60%, the recrystallization temperature drops to 650 ℃. The recrystallization annealing temperature of cold deformed austenitic stainless steel is 850~1050 ℃. At 850 ℃, it needs to be kept warm for 3h. At 1050 ℃, it can be fully burned, and then water-cooled.
Adjust the ratio of austenite forming elements to ferrite forming elements in the steel to make it have austenite + ferrite dual phase structure, in which ferrite accounts for 5-12%. This dual phase structure is not easy to produce intergranular corrosion.

Total quality assurance.Sound or limit of service life has the effect of caching, greatly reducing pipeline deformation and enhancing the service life of the pipeline!
The flat surface shall not be polished with grinding wheel], the surface of the equipment after treatment does not guarantee the flatness of the shell. With this treatment process, the overall equipment investment will be high.
Change the included angle with the weldment, change the welding speed, etc. to change the temperature of the molten pool, so as to ensure that the weld formation is beautiful (the width is consistent, and there are 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 coating
Flourishing.Molten salt has strong oxidizing power, low melting point and small viscosity. In the production process, only the sodium halo content is not less than 8% (WT). It shall be treated in a salt bath furnace at 450 ~ 470 ℃ for 5 minutes for ferritic stainless steel and 30 minutes for austenitic stainless steel. Again,
Iron oxide and spinel can also be oxidized by salt to become loose ferric oxide, which is easy to be removed during acid pickling. Due to the high temperature, the formed oxide is partially peeled off and settled at the bottom of the furnace in the form of sediment. Alkaline salt melting pretreatment process flow: steam oil removal → Preheating（
Design integrity. Chromium containing stainless steel also integrates mechanical strength and high extensibility. It is easy to process and manufacture components, and can meet the needs of architects and structural designers.
