and take appropriate ventilation measures indoors.

Check whether the sealing ring of pipe fittings is complete and clean and whether the placement position is correct. If there is dirt please take measures to block the net

Windproof and ventilation. Where there is wind, it must be cleaned up. If the sealing ring is damaged, it must be replaced again.

.Good ductility, used for forming products. It can also be machined to harden rapidly. Good weldability. Wear resistance and fatigue strength are better than stainless steel.

Spcespce & mdash; & mdash; refers to cold-rolled carbon steel sheet and strip for deep drawing, equivalent to China 08Al (52) deep drawing steel. If it is necessary to ensure non aging property, add n at the end of the brand as spcen. Quenching and tempering code of cold-rolled carbon steel sheet and strip: annealing status is a standard quenching and tempering is s, 1 / 8 hard is 1 / 4, hard is 1 / 2, hard is 1. Surface processing code: dull finish rolling is D, bright finish rolling is B. spcc-sd represents cold-rolled carbon sheet generally used for standard quenching and tempering and matt finish rolling. Another example is spcct-sb It refers to cold-rolled carbon sheet with standard quenching and tempering and bright processing and required to ensure mechanical properties.

.The best choice is also frequently launched in the market. If you want to buy a stainless steel water supply pipe with quality assurance, how should you choose?

In the building water supply pipe system, since the galvanized steel pipe has ended its glorious history of one hundred years, various new plastic pipes and composite pipes have developed rapidly. The professional stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe have advanced technology, strict testing, more affordable price and more preferential treatment. Welcome to consult. However, there are still some deficiencies in various pipes to varying degrees, It is far from fully meeting the needs of water supply pipeline system and national requirements for drinking water and related water quality. Therefore, relevant experts: building water supply pipes will eventually return to the era of metal pipes. According to foreign application experience, stainless steel pipe is recognized as one of the pipes with good comprehensive performance in metal pipe. Chemical analysis: carry out chemical analysis on the chemical composition of the material, and the chemical composition meets the requirements

5cm thick stainless steel plate shall be processed with special cutting tools, such as laser cutting machine with large wattage

The large electric clamping tool is 220V power supply, and the motor drives the oil cylinder to clamp. The connecting oil pipe and quick connector must not be contaminated, otherwise the dirt entering the oil circuit system will affect the normal use of the tool. Connect the main engine and hydraulic cylinder, turn on the power supply first, then tighten the pressure relief valve, wait until the pressure gauge rises to about 45MPa, or the main engine automatically trips, then open the pressure relief valve, turn off the power supply, and remove the tong head after complete pressure relief.

Restate the quality of stainless steel pipe, such as stainless steel pipe, we promise & ldquo; 8 chromium and 18 nickel & rdquo; Penalty for false and provide quality inspection report and certificate of conformity.

Honesty and mutual benefit.In polluted air (such as atmosphere containing a large amount of sulfide, carbon oxide and nitrogen oxide), in case of condensed water, acetic acid liquid points will be formed, which will lead to chemical corrosion.

6 Density 400 & rdquo; Density of series: 93310s, 309S and 316316 density stainless steel coils of 30323042001 are divided into Austenitic, ferrite, duplex (ferrite austenite) stainless steel cold rolled coil and stainless steel hot rolled coil.

The requirements for weldability and weldability vary from product to product. A tableware usually does not need welding performance, and even includes some pot enterprises. However, such as class II tableware, thermos cup, steel pipe, water heater, water dispenser, etc.

After the installation of stainless steel water pipe cleaning pipeline, it is recommended to use 3% potassium permanganate for disinfection. It is strictly prohibited to use bleaching water for disinfection, and clean it with clean water after disinfection. If it is not put into use for a short time, so as to prevent the corrosion reaction between oxygen free in the pipe and other media.

Welcome to inquire.Cold formed alloys can be cut and cold formed. However, due to its high strength and hardness, the alloy needs cold forming more than austenitic steel. Because of its high strength, such as 1 thousandth of 1Cr18Ni9 (i.e. 0.1% C), stainless C & le; 0.08%, such as 0CR18NI ultra low carbon C & le; 0.03%, which is equivalent to q195a. 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.

.Hot rolled stainless steel tubes are generally produced on automatic tube rolling mills. After inspection and removal of surface defects, the solid pipe blank is cut into the required length, centered on the end face of the perforated end of the pipe blank, and then sent to the heating furnace for heating and perforated on the piercer. During perforation it rotates and advances continuously. Under the action of roll and plug, which is called rough pipe. Then it is sent to the automatic pipe mill to continue rolling. After that a cavity is gradually formed inside the pipe blank, the wall thickness of the whole machine is adjusted, and the diameter is determined by the sizing machine to meet the specification requirements. It is advanced to produce hot rolled seamless steel pipe by continuous pipe mill.

Its plastic toughness is lower than that of austenitic stainless steel, and its cold and hot working process and formability are not as good as that of austenitic stainless steel.

The shielding gas is argon with a purity of 999%. When the welding current is 50 ~ 50a, the argon flow is 8 ~ 0lmin, and when the current is 50 ~ 250A, the argon flow is 2 ~ 5lmin.
