The China Petroleum Enterprises Association and China Oil and Gas Industry Development Research Center released the "2016 China Oil and Gas Industry Development Analysis and Outlook Report Blue Book" on March 21, stating that the oversupply of global oil in 2016 will cause the overall international oil price to continue to be sluggish. For stable growth. At the same time, China's total oil refining capacity reached 503 million tons per year at the end of 2015, becoming the world's second largest oil refining country after the United States. China Petroleum Enterprises Association points out that oil prices continue to be low ...
Surface treatment of the sleeve (1) bright chrome: very bright like a mirror surface (2) chromite: matte (3) electrophoresis: black, with brightness. Under the action of an external DC power supply, the charged particles are directed to the cathode or anode in a dispersed medium to promote the separation of the materials; (4) Phosphating: black, but no gloss. The sleeve is immersed in a phosphating solution, and a layer of water-insoluble crystalline phosphorus is deposited on the surface, which is the conversion process of phosphate. Bayer's sleeve manufacturing process blank (with a variety of rules ...
Recently, my Bayer after-sales service team organized a technical training for hydraulic torque wrenches before a maintenance for a project department of PetroChina, especially for new employees to increase their training efforts, and strive to make them proficient in the correct operation method in the shortest time . It can reduce the labor intensity of workers, greatly improve the efficiency of maintenance, and the customer's response is good.
The quality of oil products produced or purchased by petroleum refining and chemical companies, oil sales companies, etc., need to undergo various tests that meet ASTM standards. Fast and accurate detection is the top priority for ensuring the implementation of current policies. In response to the testing needs of major petrochemical industries, DKSH held a seminar on the petrochemical industry at Shanghai Keya International Hotel on the 17th of this month, and invited the executive director of ASTM. XRF application experts will introduce ASTM Petrochemical in detail for everyone Industry standards and their development, and XRF ...
1. The stretching method of Bayer stretcher is not affected by the effect of bolt lubrication and thread friction, and can obtain more accurate bolt load. 2. Bayer series tensioners can simultaneously stretch multiple bolts, so that the entire circle of bolts is evenly stressed and gets a balanced load. 3. Due to the use of the most advanced ultra-high pressure technology, the Bayer stretcher can complete the disassembly and assembly of bolts in a small space. 4.The residual load and effective load obtained by tightening the bolt of the Bayer stretcher are compared ...
Introduction: Bolt tensioner is the abbreviation of hydraulic bolt tensioner and hydraulic stretcher. It uses the hydraulic source provided by the hydraulic booster pump (ultra-high pressure hydraulic pump), according to the tensile strength, yield coefficient and elongation of the material. Determine the tensile force, and use the tensile tension generated by the ultra-high pressure oil pump to make the bolt to be stretched in its elastic deformation zone, and the diameter of the bolt is slightly deformed, so that the nut is easy to loose, and it can also be applied as a hydraulic interference connection Axial force device for top pressure installation. Stretcher max ...
