Recently, Zhejiang Lin'an Special Welding Electrode Factory successfully developed a brand new valve sealing surface Wolong surfacing electrode :5.0-4 .0 mm

D507 rod ,5.0-4 .0 mm.G207D electrode.
"The two Nickel Electrodesare used to optimize drug formulations leather production process, excellent welding performance and greatly reduce the cost of

production valve, the valve company has supplied a number of" head of the company to the Chinese pump valve website, the company the use of advanced

technology R & D and innovative structural design successfully developed the Wolong brand new valve sealing surface welding electrodes, has passed expert

acceptance and mass production.

It is reported that Zhejiang Lin'an Special welding plant is located in Hangzhou Lin'an western suburb ---- Founded in 1994, formerly a subsidiary of Shanghai

Material Research Institute experimental project, long-term and Shanghai welding plant, welding rod factory in Hangzhou, Zhejiang University universities and

research institutions and technological exchanges and explore, and strive to meet the market development and demand.

Lin'an Special welding plant after ten years of technology research and production practice in the domestic field is unique in the industry. Independently

developed a variety of new technical welding, including CTNB Cowden steel electrode (TAC-16 electrodes), JNS acid steel electrode (J427CrCuSb), ND

electrode, 10CrMoAl seawater corrosion-resistant steel welding rod: the sea 03 Welding Electrodes, high-quality sealing valve surface electrodes and other welding

electrode D507, another anti-hydrogen sulfide, hydrogen chloride 08Cr2AlMo, including steel welding rod (ie, OA electrode) filled a gap in the market. In

addition, the factory also has R & D capability, according to business needs, design, development, production and products.
