boiler Factory Direct Supply Industrial 20t Cambodia

Wuhan Port District Social Welfare Institute (apartments for the elderly) is invested by the government pension services, with a total construction area of ​​38,000 square meters, 532 beds, mainly adopt destitute persons, social support on behalf of the elderly. Hope to provide welfare to the elderly year-round 24-hour hot water, the original boiler factory direct supply industrial 20t cambodia equipment can not meet this demand, therefore, require additional purchase orphanage hot water boiler. After much investigation, in cooperation with the welfare determined fast boiler, provides three integrally condensing gas hot water boiler (WNS1.4-1.0 / 95/70-Y.Q) by a fast boiler.

Fast boiler factory direct supply industrial 20t cambodia - product sales throughout the country and exported to Indonesia, Russia, North Korea, South Korea, the Philippines, Vietnam, Thailand, Australia, Mongolia, India, Singapore, Oman, Europe and America over 60 countries and regions; user groups involved in grain and oil , chemicals, building materials, textiles, military units, schools, hotels, heating and other industries, 80,000 + successful cooperation.

The inspection requirements for boiler factory direct supply industrial 20t cambodia welded joints are made on the basis of listening to the opinions of the relevant units and referring to the regulations of the relevant codes. This code does not require gas-phase furnace and liquid-phase furnace respectively, but different requirements according to different pressure components. 1. The longitudinal ring weld seam of the boiler drum and the joint of the head of the boiler shall be ray or ultrasound plus at least 25% ray detection, which is basically consistent with the requirements of the current steam boiler and hot water boiler code, Only the requirement for ultrasonic plus at least 25% x-ray flaw detection has been added, the same as the 80 version steam boiler code requirements. This provision mainly considers ultrasound plus 25% X-ray detection, complete The defects in the weld can be detected to meet the safety requirements, and the production cost can be reduced. 25% X-ray inspection must include the longitudinal seam and the circumferential cross joint. 2. The inspection of the butt joint of the heating surface pipe is required according to the different heat condition. Heat is different from radiative heat and convective heat. In the draft for advice, 25% and 10% spot tests are prescribed respectively. Among the feedback, some thought the requirement was lower, and suggested that it should be changed to 50%; some thought the requirement could be lower. Through analysis and research, we have adopted the latter opinion that the radiation range is no less than 10%. X-ray inspection; convective section not less than 5% X-ray detection. Gas shielded welding should be adopted in butt weld of heated surface pipe, and the quality can be guaranteed. In addition, the method of flaw detection and the calculation of sampling rate are stipulated in this regulation, which makes this procedure more operational. 3. Except for the drum of the gas furnace, the boiler drum of the liquid phase furnace, the heating surface pipe of all organic heat carrier furnaces and the butt joint of the pipe shall not be required to carry out the mechanical performance test. Therefore, this regulation only for gas boiler drum batch production of each 10 to do a test plate. There is no requirement for a test board in any other case. . The use pressure of liquid phase furnace is relatively low. At the same time, not only the welding method is specified clearly in this code, but also the requirements for welding procedure evaluation are put forward, which can guarantee the quality and performance of welding seam.

4. Suspension structure is good for absorbing boiler factory direct supply industrial 20t cambodia expansion and makes it safe in operation.

5. Closed ash discharging device makes it achieve flue gas side seal box automatic slag discharge.
