Among the steel products exported by China, steel pipe has always been the focus of foreign anti-dumping and countervailing investigations. The Russian Ministry of industry and trade announced an anti-dumping investigation on China's cold-rolled stainless steel seamless steel pipes exported to the Russian Belarus Kazakhstan customs union. Before that, the Brazilian foreign trade chamber also said that it would impose an anti-dumping tariff of US $743 per ton (about RMB 4748 yuan) on China's steel pipe products, which is valid for five years.

.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 15 & deg; & mdash; 20 & deg;; correct the molten pool temperature welding wire and weldment should be maintained. The ideal caster angle of the welding handle nozzle is 70 & deg; & mdash; 80 & deg;, 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, 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 12 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 45 & deg; the slope shall be gentle, and pay attention to the defects such as arc pit and shrinkage hole during arc stop.

In order to obtain seamless pipes with smaller size and better quality, cold rolling, cold drawing or a combination of both must be used. Cold rolling is usually carried out on a two high mill. The steel pipe is rolled in an annular pass composed of variable section circular groove and fixed conical plug. Cold drawing is usually carried out on a single chain or double chain cold drawing machine of 0.5 ~ 100t.

Model 416 & mdash; The addition of sulfur improves the processability of the material.

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,304 stainless steel heating pipe, professional stainless steel plate stainless steel coil, stainless steel belt and stainless steel pipe have stable, safe and reliable performance and can be maintenance free. The technical level has reached the domestic level and the advanced level of similar international products. Other local corrosion resistance properties are better than ferritic stainless steel.

Compared with traditional steel, stainless steel can not only ensure high strength and weight ratio, but also have good plasticity, formability and weldability. It is the first choice for car frame. Stainless steel with superior performance can create cars with light weight, strong resistance, high safety and long service life. Such frames can be recycled and reused. It can not only save costs, but also save resources. And some other auto parts are also made of stainless steel. Stainless steel has a great potential market in the whole automobile industry!

Where is it.The pipe fittings must rotate slowly facing the pipe. If they are tight,Stainless steel water pipe 304, please use clean water pipe fittings and sealing rings.

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, welding wire and weldment should be maintained. The ideal caster angle of the welding handle nozzle is 70 & deg; & mdash; 80 & deg;, and the included angle between the welding wire and the weldment surface is 15 & deg; & mdash; 20 & 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, no concave, convex and other defects) During operation,Stainless steel pipe manufacturer, 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 12 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 pay attention to the defects such as arc pit and shrinkage hole during arc stop.
