Tubing Spider And Api Spiders

Differential spider - Used in axials

Api vacuum insulated tubing Skype: julia0402zcy wechat: juliazcy Product name: pre-stressed vacuum insulated tubing/casing Product explanation: 1. Reduces the heat loss, ensures the steam quality being injected into the oil formation as well as the depth of steam injection can be increased. 2. Minimizes heat stress on well casing and cement mantle, protect the casing from damage by high temperature. 3. During oil production it will provide superior insulation and greatly reduce the loss of heat energy Product features: 1. The pre-stress will compensate the tubing expansion caused by temperature difference between the inner and the outer tubes so as to ensure reliable operation under high temp. 2. Gas absorbing materials are packed inside the annulus to clean up harmful gases and maintain good insulating property whilst in service.

1. Brief description CD1 electric hoist has only normal speed, which can satisfy the general working requirement. MD1 electric hoist has one more hoisting motor and one slow speed actuating device, which make the model have two speeds. When it works slowly, it can satisfy the precise task such as precise working of loading and unloading, sand to break-in. 2. Applications It can travel rotation through the trolley hanging on the I-steel, and install on the single beam crane, gantry crane, jib crane and overhang crane to rise and fall the cargos. So it can be used in factories, mines, wharf, warehouse, freight yards, and shops and so on which need lifting equipment for lifting heavy objects. Such as mining companies and railways, docks, warehouses. It is prohibited to manned. 3. Components Motor: Hoist Motor is an taper type rotor motor with braking,it is made by Nanjing special motor factory,it is of the best quality motors, it has bigger torque, so it can be adapted to moving frequently. Trolley: It is assembled and has running wheels. Herein, the runner wheels are mounted on top-class sealed ball bearings. Gear Box: Hoist Gear Box has specially treated gears for high wear resistance. Each Geared Shaft assembly is supported on ball or roller bearings , to ensure smooth, low-friction operation. Wire Rope: Hoisting rope comply with the exporting ISO standards. The leading rope taken by the Drum, does not slip sideways when slack. The factor of safety, on the nominal breaking strength of the rope is six. Rope Drum: Grooved Drum, seamless pipe of adequate length to be wounded in one layer and to provide proper support for the rope to minimize abrasive wear is provided. Drum Shaft resolves on Ball Bearings for ensuring smooth running. Electric control system: Model CD1 and MD1 is composed of the contactor box,controlling switch,cut-off limiter.the working voltage of controlling switch is 380V,36V or 24V(safety voltage). Rope Guide: Rope Guide is in two halves, ensuring easy accessibility. It encircles the Drum completely so that the rope may not uncoil even when the Hoist is in unloaded condition. Hook: The Hook Block is tested to 150 % of full load before assembly. The rope sheaves are fully guarded with protective steel casting . Testing: All our Hoists are tested on 125 % thus assuring safe working load and is issued with a test certificate. If you need other type electric hoist, please tell us, we will be pleased to be of further assistance!

Jm model slow speed electric winch is most commonly used winch in construction site or workshop, etc. And power supply for the electric winch varies from 110v-440v/50&60hz according to different countries’ situation. The electric winch also can divided into: construction winch, marine winch, mine winch, building winch, cable winch, etc. With different models, speeds and structures, electric winch is used widely, such as road construction, bridge construction, factory, mines engineering, harbor, building, etc. 1.Loading capacity:0.5~200 ton or customized design; 2.Wire rope capacity:20~3600m or customzied design; 3.Working speed:5~20 m/min or customized design; 4.Power supply:220~690v, 50/60hz, three phase or customized design.
