Anqing Petrochemical urea equipment poison gas detection alarm design

A few days ago, Anqing Petrochemical Plant held a project design review meeting for the addition of a fixed toxic gas detection alarm device for urea plants in the conference room of Science and Technology Building 401. The meeting listened to the presentation of the design of the project by representatives of the design team of Shihua Company. The participants held serious discussions. The meeting agreed in principle with the project design of the “Urea Addition of Fixed Toxic Gas Detection and Alarm Device” compiled by Shihua. Divisional Technology Development Department, Comprehensive Planning Department, Production Department, Mobile Division, Annuan Department, Finance Department, Audit Department, Material Supply Center, Chemical Fertilizer Division II, General Plant Electrical Apparatus Department, Shihua Engineering Design Co., Ltd., etc. Related personnel attended the meeting.
Anqing Petrochemical's urea plant is an important part of the Anqing branch company. Once evaporated, ammonia, formaldehyde, etc. in the production area of ​​the plant will not only be very toxic, but also have a great harm to the environment. In order to ensure the safe production of the equipment after “oil to coal”, Anqing Petrochemical decided to add a stationary toxic gas detection and alarm instrument to the urea plant, requiring the chemical fertilizer department and Shihua Company to cooperate with each other. According to the actual toxic gas detection, the alarm system can be reasonably performed. The layout and installation. In addition, detailed requirements have been made for the selection and installation of toxic gas detection alarms.

Laser Cladding Powder

Nickel Based Laser Cladding Powder

Ni base alloy powder is mainly made of NiCrBSi or NiBSi. Ni-based self-fluxing powder has good wettability, corrosion resistance and high temperature self-lubricating effect, and is used in components with heat resistance, corrosion resistance and thermal fatigue resistance. In general Ni35,Ni45,Ni60 etc can be used for laser cladding, the No means hardness of powder. Inconel 625 and 718 has good corrosion property under higher temperature, also widely used for laser cladding process.

Cobalt based Laser Cladding Powder

Cobalt-based alloy powder is the cemented carbide resistant to various types of wear and corrosion as well as high temperature oxidation. That is, the so-called cobalt-chromium-tungsten (molybdenum) alloy or Stellite alloy cobalt-based alloy is mainly composed of cobalt, containing a considerable amount of nickel, chromium, tungsten and a small amount of molybdenum, niobium, tantalum, titanium, Alloying elements such as lanthanum, and occasionally a class of alloys containing iron.

Co-based self-fluxing alloys have good high temperature performance and wear resistance and corrosion resistance, and are used in petrochemical power, metallurgy and other industrial fields where they are wear-resistant, corrosion-resistant and high-temperature resistant.

Iron based Laser Cladding Powder

The work pieces required for laser cladding and manufacturing in the actual industry are mainly carbon steel and cast steel. The Fe-based alloy is close to the base material in composition and has good wettability. The advantage of Fe base powder is lower cost and good wear resistant of cladding layer. As a result, it`s the most widely used for laser cladding process. It is suitable for parts that require local wear resistance and are easily deformed.

WC blended Laser Cladding Powder

Tungsten carbide blended with Ni alloy powder is the best choice for wear resistant work piece. This unique process can bring excellent wear, corrosion and high temperature resistant. Our blend powder can achieve different portion of WC from 35% to 60% without crack under suitable cladding parameter.
