300HP fire tube boiler
Boiler surface quality of the weld quality of the weld surface of the 300hp fire tube boiler requires requirements: (1) should meet the dimensions of weld design requirements and technical standards, weld and base metal should be a smooth transition, is not less than the height of the weld surface of the base material . (2) the weld heat affected zone and the surface does not allow cracks, pores, craters, and macroscopic defects such as slag. Vertical (3) of the pressure element, and the circumferential weld seam stitching head no undercut, partially undercut the remaining weld depth of not more than 0.5 mm. Sides undercut weld pipe total length of not more than 20% of the circumference of the tube. (4) grinding the weld surface after the elimination of defects or mechanical damage thickness not less than the thickness of the base material. (5) on both sides of the slag and weld spatter must be removed.
Before GAOAN gas steam 300hp fire tube boiler installer to install gas steam boiler, which must be completed "boiler installation started this book", and includes not only carry the following material contained in the gas to the boiler steam boiler for all management authority belongs to the Office of the boiler installation procedure, the before construction can agree: ① gas steam boiler installation approves the application is a copy; ② gas steam boiler installation boiler installation boiler room and started this book project plan; ③ gas steam boiler certificate nameplate data; ④ equipment plane between CAD drawings and equipment between design information; ⑤ installation unit farm installation work qualifications of employees. Former gas steam boiler installation, installation of the unit must also carry a complete agreement "boiler installation started this book" to everyone belongs to the quality control unit detects the gas pressure equipment steam boiler at the signing "an undertaking boiler installation quality", by the detection of the the value of the gas steam boiler installation of required supervision.
Zhengzhou Sunrise Optoelectronics Technology Co., Ltd. by the Dongxu Group, Henan Province, the state-owned asset management companies and Zhengzhou Investment Holdings Limited jointly made, mainly engaged in flat panel display and solar industry design materials, manufacturing and sales operations. Sunrise Optoelectronics project has been put into a production line, the second phase will continue the expansion, three new production lines to meet the production needs of Project Phase II, Sunrise Optoelectronics urgent need to increase new 300hp fire tube boiler equipment. After investigation and screening of a number of boiler brands, determined to cooperate with the fast boiler, steam signed a 10-ton integrated condensing gas steam boiler (WNS10-1.25-Y.Q).
Gas 300hp fire tube boiler cleaning process:
The first step: cleaning cleaning, according to the share of circulating water in the cleaning tank cleaning equipment is good to participate in the cleaning agent, boiler cleaning cleaning carried out, according to the amount of dirt to determine how much time cleaning cycle and how many agents participate, confirm all quality cleaning dirt after down into the next washing program.
