Electric fence for commercial security
Electric security fences are the absolute answer to corporate and commercial security Can be perfectly adapted for use in office parks, ensuring the protection of all precious assets. What makes our electric fence so ground-breaking is that it is built within the frame of a robust and heavy-duty barrier fence. The barrier provides the traditional security of a barrier obstacle, restricting unwanted movement by both trespassers and animals, while the electrified charge can dissuade the most determined of intruders. Due to the electric fence maybe used in parks, please put a prominent signs fixed to the fence marked "dangerous" or an electric symbol . Advantages of electric fencing Effective stock control achieved by physical, visible and psychological means. Risk of injury lower than for non electric fences especially barbed wire. Less expensive to install than conventional fencing. Versatile. Easily and quickly erected. Variety of design possibilities. Can be permanent or portable. Existing fences can be electrified. Low maintanance. Contact:

Boiler sheet 16MnDR Grade B SLA325B P355GH low alloy high strength pressure
Boiler pressure vessel steel sheet is mainly used to manufacture superheater, main steam pipe and boiler fire chamber heating surface used in hot rolled medium thick plate material. Boiler steel plate is one of the very key materials in boiler manufacturing, mainly refers to the hot rolled special carbon steel and low alloy heat resistant steel medium thick steel material used to manufacture boiler shell, pot drum, box end cover, hanger and other important parts.It includes carbon steel, carbon manganese steel, microalloy steel, low alloy high strength steel and low temperature steel. Operating temperature is generally -20℃ to 500℃, individual up to 560℃. These are mainly 16MnR steel (16 manganese capacity low alloy steel, a type of steel), which is used in the manufacture of ASME code pressure vessels. 16MnDR is a kind of steel plate for cryogenic pressure vessel. 16Mn -- indicates that manganese content in steel plate is about 0.16%, D- indicates low temperature, R- indicates pressure vessel. (Usually, steel with a high content of a certain chemical element needs to be marked in the material, for example, 1.6% manganese is written as 16Mn, 16MnDR is used for -40 degree pressure vessel steel plate.

ASTM A312 TP316L TP304L Stainless Steel Seamless Pipe For Oil And Gas
ASTM A312 TP316L TP304L Stainless Steel Seamless Pipe For Oil and Gas Standard specifications include seamless, longitudinally welded and cold welded austenitic stainless steel pipe for high temperature and general corrosive service. This standard is divided into several grades, each steel grade should determine the required chemical composition C, Mn, P, S, Si, Cr and Cr, Ni, Mo, etc. Process according to desired heat treatment temperature and cooling/testing requirements. It also needs to meet the specified tensile strength and yield strength. Chemical Composition for TP304 and TP316 ASTM A312 TP316L TP304L Stainless Steel Seamless Pipe For Oil And Gas 0 A: New designation established in accordance with Practice E527 and SAE J1086 Mechanical Properties ASTM A312 TP316L TP304L Stainless Steel Seamless Pipe For Oil And Gas 1 A312 Pipe Manufacturing Types ASTM A312 pipe covers following manufacturing types (Including hot finished or cold finished): a. Seamless Pipe (SMLS): It covers stainless steel seamless pipe that manufactured in any process that can not be involved in the welding process. b. Welded Pipe (WLD): It covers welded pipe that manufactured by an automatic welding process that does not add filler metal during welding. c. Cold Worked Pipe (HCW pipe): The heavy cold-worked pipe that apply cold working of not less than 35% reduction in thickness of both wall, and welded to the welded pipe prior to final annealing. Do not use fillers during welding. d. Welded and HCW pipe: Welded pipe and HCW pipe of 14 and smaller than NPS 14 shall have a single longitudinal weld. After approval by the purchaser, the welded pipe and HCW pipe with an NPS greater than NPS 14 shall have a single longitudinal weld or shall be manufactured by forming and welding two longitudinal sections of flat stock. So each welds are to be tested, inspected, inspected or treated. ASTM A312 pipe shall be free from oxide scale and contaminated iron filings. If the steel pipe is brightly annealed, and pickling, blasting or surface finishing may not be mandatory. The purchaser can request that the finished pipe shall do passivating treatment. Heat Treatment Methods ASTM A312 stainless steel pipes shall be furnished in heat treatment condition comply to table 2 of ASTM A312. In case of seamless types, immediately following hot forming while the temperature of the pipes is not less than the minimum solution treatment temperature specified in this table, pipes shall be individually quenched in water or rapidly cooled by other means (direct quenched). ASTM A312 TP316L TP304L Stainless Steel Seamless Pipe For Oil And Gas 2 B: Minimum, unless otherwise stated C: Quenched in water or rapidly cooled by other means, at a rate sufficient to prevent reprecipitation of carbides, as demonstrable by the capability of pipes. heat treated by either separate solution annealing or by direct quenching, of passing Practices A262, Practice E. The manufacturer is not required to run the test unless it is specified on the purchase order (see Supplementary Requirement S7). Note that Practices A262 requires the test to be performed on sensitized specimens in the low-carbon and stabilized types and on specimens representative of the as-shipped condition for other types. In the case of low-carbon types containing 3% or more molybdenum, the applicability of the sensitizing treatment prior to testing shall be a matter for negotiation between the seller and the purchaser. Mechanical Test Mechanical test including heat treated condition, Transverse or Longitudinal Tension Test or Flatten Test. Transverse or Longitudinal Tension Test For lots of not more than 100 pipes, one specimen shall be taken for tensile testing. For lots of more than 100 pipes, two specimens shall be taken from two pipes for tensile testing. Flatten Test For material heat treated in batch furnace, (by quenching after hot forming or in a batch-type furnace equipped with recording pyrometers and automatically controlled within a 30℃ or less range) 5% of steel pipe should be taken from each heat treated lot for flattening test. For material heat treated in the continuous furnace, sufficient number of pipe to constitute 5% of the lot, but in any case not less than 2 lengths for flattering test.
