We can produce the lower-temperature steel pipe according to the ASTM A333 and ASME SA333 standards, and the and the production diameter from 8" to 48" in OD and wall thickness from 9.53 mm up to 140mm. We have been sold the GR.6 steel pipe about 20000 tons to date and the property of -45℃ impact value is about 100J, better than the standard`s requirements.
Yangzhou Chengde has the full capability to do every test in-house, from mechanical testing, chemical analysis, PMI, UT/Hydrotest etc. Chengde`s lab is qualified to ISO 17025 and CNAS standard, being proven the repeatability of accurate testings.
Each alloy pipe is subject to PMI before dispatch. The INNOV-X system performs non-destructive chemical analysis via simultaneous detection and quantification of fluorescent x-rays of multiple elements in test sample.

Common concentrated copper-nickel ore separation technology solutions In general, there are two copper-nickel ore beneficiation technologies used in most copper-nickel separation technology applications: copper-nickel mixed concentrate separation and high-ice nickel separation process. So what is the difference between the two? Very simple, the mineral properties of the two are different. The copper-nickel mixed concentrate separation technology is suitable for copper-nickel ore with coarser grain size and less tightly embedded relationship. The high-ice nickel separation process is just the opposite. Copper-nickel minerals are fine-grained, densely packed with copper-nickel ore.
From two success stories to look at cloud Nankunmingkun Ding heavy machine copper-nickel ore separation technology and equipment copper-nickel mine in Guizhou even copper-nickel mine is symbiotic metal sulphide copper-nickel mine, cloud Nankunmingkun Ding heavy machinery in 1990 It has designed a complete set of copper-nickel separation technology schemes. The main processes and summary copper-nickel mine equipment are mainly: the three-stage and one-closed process is adopted for the crushing process, and the three-stage grinding is adopted for the subsequent grinding and hydraulic flotation. Mine-three-stage flotation of refined copper-nickel ore equipment operation process.
In a copper-nickel mine in the northeast, the copper-nickel separation technology process plan uses a three-stage closed-circuit crushing, stage grinding, copper-nickel mixing, separation flotation, nickel concentrate three-stage dewatering, and copper concentrate two-stage dewatering operation.
Common copper-nickel ore smelting methods In the case of domestic copper-nickel ore equipment, most of them use the smelting technology of fire method. The rough operation process of the copper-nickel ore equipment smelted by fire method includes: preparation (baking) - smelting - blowing - refining (electrolysis) several main processes.
In the process of mineral processing in nickel ore mines, copper- nickel symbiosis is often encountered, while copper is a useless impurity in nickel ore beneficiation and smelting, which will affect the beneficiation technical indicators such as the grade of the final nickel concentrate, but Yunnan copper and nickel. The expert of mineral ore dressing technology advises users that if the copper in the copper-nickel ore has the recovery value, it should adopt the copper-nickel separation technology with better economic benefits and the supporting copper-nickel equipment for comprehensive recovery. Therefore, in this article, the copper and nickel ore dressing technology experts of Kunming Kunming Heavy Machinery in Yunnan Province will introduce the copper-nickel separation technology and related copper-nickel ore equipment of our factory in detail.
