Henan malpractice Construction Engineering Testing Co., Ltd. is a professional testing company, is one of the qualification place in Henan Province since the first detection through examination of business. Business in the Pile qualification qualification, the qualification grade steel, a qualified indoor environment, building energy efficiency testing, subject testing, materials testing, curtain detection, detection of roads and bridges, air defense projects to detect a number of test qualification and testing laboratories. Material that is outside the friction material mass and volume loss caused by the phenomenon known as wear and tear. Material by both friction and impact the quality and volume of the two effects caused by the phenomenon known as the abrasion loss. Building for the ground, stepping, steps, pavement materials, etc., should give due consideration to wear; pavement materials used in road works, must consider the wear and abrasion resistance performance; hydraulic engineering, such as overflow dam overflow face, sluice and concrete floor and other parts, often by scouring effect of high-speed stream of entrained sand or gravel bottom entrained flow impact action and destruction, Yima construction engineering inspection, these parts need to be considered material to resist wear and abrasion performance. Greater hardness, high toughness, more dense structure in real time, its strong resistance to wear and abrasion.

Determination of yield strength and tensile strength testing machines ① adjustment disc pointer, engineering testing to align zero, and struck deputy pointer, the principal deputy pointer overlap. ② the specimen fixed in the grips of the machine, Mianchi construction engineering testing, tensile testing machine start. Tensile speed: before yield stress increase rate of 10MPa / s; after yielding, tester movable chuck moving speed under load is not more than 05Lc / min (without turning the specimen Lc = l0 + 2h1). ③ stretch, the measured intensity of the disc pointer stops when rotating constant load, or excluding the minimum load during the initial transient effects, the yield strength of demand is the load Ps. ④ until it pulled off the specimen continuously applied load, maximum load Pb is read from the measured intensity of the disc. Engineering testing, Henan malpractice detected by detecting Yima Henan Construction Engineering Construction Engineering Testing Co. malpractice. Engineering testing, Henan malpractice detection, detection is the Henan Yima Construction Engineering Construction Engineering Testing Co., Ltd. Risheng (www.hnrsjc.cn) (www.rsgcjc.com) this year introduced a new upgrade, the above picture is for reference only, please call Tel or pictures on this page, for the latest information, contact: Wang Wei.
