tubes. Huayu also produces seamless and welded titanium tubes, as well as pure nickel and nickel alloy seamless tubes, following the introduction and commissioning of new production lines last year. AMI Dutchmetals is the exclusive European representative for all Huayu Non-Ferrous Metal Industries tube products. The mill benefits from full TUV certification, possessing ISO 9001, ISO 14001 and PED accreditation. In addition to dedicated production and QAC staff, the mill has an extensive maintenance team. The company welcomes independent third-party inspections, which are carried out on a that allow for efficient heat transfer. These integral ridges improve the efficiency of heat exchangers in which refrigerant condenses or evaporates within the tube. The smooth surface tube products can be supplied in level wound coils, or in straight lengths. Inner grooved copper tubes are found in residential and commercial air con- ditioning and refrigeration applications. The company’s seamless inner grooved tube’s (IGT) highly precise dimension and integral groove shape increases the efficiency of heat exchangers, continuously driving improvements in environmentally friendly refrigerants. that has been equipped with a copper tube purging (CTP) system. This system provides a protective atmosphere through level-wound copper tube coils during the annealing process. To ensure product quality in the domestic and foreign market, the company’s test facilities have been equipped with modern equipment such as German eddy current testing, German optical emission spectrometer, English tensile tester and Japanese

Capilator © tube is Wolverine’s capillary tube, used throughout the refrigeration and air conditioning industry for flow restriction applications. These tubular components are produced in copper hard drawn straight lengths. Control Tube is a small bore annealed tube used in applications such as heat loop and pressure control for refrigeration manufacturing. Control Tube is available in straight lengths, level wound coils and bunch coils.

Industrial tube from Wolverine Tube, Inc consists of small and medium- diameter copper tube made to customer specifications for equipment manufacturing. Industrial tube products include coils in lengths of up to one mile (to permit economical transport to customers for further processing), smooth straight tube, internally-enhanced tube with internal surface ridges to increase heat transfer in air conditioning coils, and very small diameter capillary tube (as small as 0.01") for control valve operations. Wolverine Tube’s smooth surface tube components have helical integral ridges Qaem Copper Industries Company, a producer of seamless copper tube including LWC (plain and inner grooved), straight and pancake, has developed thin-walled copper tubes. These thin-walled tubes are produced in LWC form, both in plain and inner grooved type. The tubes are lightweight and have good heat transfer compared to thicker-walled tubes. The copper tubes are clean, since they are annealed in a furnace
