中国石油集团渤海石油装备制造有限公司兰州石油化工机械厂制造商

Bohai Equipment Lanzhou Petrochemical Machinery Factory was established in 1956 and its predecessor is “Lanzhou Oil Refinery”. In March 2010 became the machinery the subsidiary corporation from “Petrochina Lanzhou Petrochemical Company” to “CNPC Bohai Equipment Manufacturing Co., Ltd.” and has been a key enterprises in developing and producing the special equipment of refining and petrochemical after 58 years’ operation. Gas expander is a kind of energy recovery turbine machinery. The working medium is the high temperature stack gas with definite pressure engendered from such technological process as oil refining, chemical industry, electric power or metallurgy industries. The working medium is expanded in the expander and shaft work is exported to drive other engines or electrical generator. Nitric acid tail gas turbine is a special turbine by the high pressure and double pressure to manufacture nitric acid. It leads waste tail gas into the turbine in the process of nitric acid production which can change heat energy and pressure energy of tail gas into mechanical energy; to drive air compressor or nitrogen oxide compressor work, so as to reduce energy consumption, improve the economic benefits of nitric acid production unit. Electro-Hydraulic Pneumatic Control Slide valve is a kind of auto control valve for the use of regulating the flow of fluid status solid granule. The medium is high temperature gas with tiny solid granule. The valve has the features of high precision, rapid response and high dependability etc. It is widely used in the catalytic cracking unit of petroleum refinery, also in other occasions with similar condition. Electro hydraulic pneumatic control plug valve is a kind of auto control valve, which can regulate the flow of solid granule. To resist high temperature medium flushing, the head and seat of valve are lined with anti-wear nonmetal. The valve is usually equipped at the bottom of vertical pipe path to control the flow of fluid status solid granule. It is widely used on the catalytic cracking unit in petroleum refinery or other occasions with same demand. Triple eccentric hard seal high temperature butterfly valve is key equipment for the oil refineries as a means of shutoff or regulating facility for high temperature pipelines, it is of corrosion –resistance, high temperature application, zero leakage and high resolution as well as quick response of open and close. Electro-hydraulic/pneumatic control high/low temperature butterfly valve is an auto control valve, which has the properties of high precision, large output torque, rapid response, steady operation and high dependability. As controlling the flow of high temperature gas, it is widely used on the catalytic cracking unit in petroleum refinery, also used in other occasions which have similar condition. Electric high temperature gate valve is an auto switch valve on the high temp gas flow pipeline with slight amount solid particles. It has the advantages of long life, low maintenance cost, small currency resistance, high temperature resistant, anti-scour and anti-fraying. The structure is tandem type double stuffing which has the features of high hardness, wide sealing surface, the special seal with steam-tight annular and lip seal, flange connection.
