Abstract
A hanger for corrosion hanging sheets of a medium-pressure pipeline is applied to corrosion resistance tests of pipelines in oil fields. The top end of the steel pipe is in threaded connection with a sealing gland, the lower end of the steel pipe is provided with external threads, and the steel pipe is in threaded connection with an upper lifting mechanism, a gate valve and a lower lifting mechanism from top to bottom; a hanging rod is arranged in the steel pipe, and a hanging hole is formed in the lower end of the hanging rod. The effect is as follows: the corrosion hanging piece for detecting the low-pressure pipeline is safely and quickly installed and taken out under the condition that the normal operation of the pipeline is not affected. The labor intensity of on-site data acquisition operation is reduced, and the accuracy and the effectiveness of pipeline operation detection are enhanced.
Description
Technical field
The utility model relates to oil field pipe conveying technology field, and particularly a kind of device of pipeline corrosion protection test is oil, feed channel operating pressure are lower than 100 ℃ middle pressure pipe road suspension corrosion coupon in 1.6～6.4Mpa, temperature a device.
Background technology
In the daily production run in oil field, often influence production run because of oil, letter shoot road inner wall corrosion or fouling, for effective inner-walls of duct prevents the burn into scale removal, interior media comprises fouling thickness, the component of inner-walls of duct to the influence of pipeline in the understanding pipeline operational process earlier.Thereby shoot the arrow at the target, deal with problems targetedly; Check the effect of various anti-corrosion measures in addition for convenience, need seek a kind of can be in the pipeline normal course of operation convenient, directly carry out the device of online suspension corrosion coupon, thereby detect pipeline operational process medium at any time to Corrosion of Pipeline.
The utility model content
The purpose of this utility model is: a kind of middle pressure pipe road corrosion coupon hanger is provided, detect pipeline internal medium to the wall erosion situation at realizing in the pipeline operational process, adopt novel sealing structure, realize in the low pressure pipeline normal course of operation, finish conveniently, flexibly and hang the corrosion monitoring lacing film in the pipeline.
The technical solution adopted in the utility model is: middle pressure pipe road corrosion coupon hanger, mainly form by sealing gland, steel pipe, last hoisting gear, slide valve, following hoisting gear and hanger bar, it is characterized in that: the sealing gland that has been threaded on the top of steel pipe, sealing gland can be with the end sealing of steel pipe.There is external thread the lower end of steel pipe, and the lower end of steel pipe can be connected with the pipe adapter on the oil pipeline.Hoisting gear, slide valve and following hoisting gear on being threaded from top to bottom on the steel pipe.A hanger bar is arranged in steel pipe, suppending hole is arranged in the lower end of hanger bar.Corrosion coupon can be suspended on the lower end of hanger bar by suppending hole.
A tooth bar is arranged on the wall of hanger bar, and what described upward hoisting gear and following hoisting gear adopted is the gear hoisting gear, in last hoisting gear and the following hoisting gear gear is arranged respectively, and gear is fixed on the end of axle, the tooth bar engagement of gear and hanger bar.Axle is connected with the handwheel of last hoisting gear or following hoisting gear outside respectively, rotates handwheel and drives axle and gear rotation, and gear rotation kinetic energy promotes hanger bar.
The principle of pressure pipe road corrosion coupon hanger in the summary.Consult Fig. 1.On hanger bar 6 walls tooth bar is arranged, the handwheel of hoisting gear 3 or following hoisting gear 5 is gone up in rotation respectively, and hanger bar 6 can move up and down.When corrosion coupon is installed, at first, corrosion coupon is suspended on the lower end of hanger bar 6; Open sealing gland 1, hanger bar 6 is put into steel pipe 2, hoisting gear 3 handwheels in the rotation, hanger bar 6 moves down.Then, close sealing gland 1, open slide valve 4; Hoisting gear 3 handwheels in the rotation, hanger bar 6 continues to move down the bottom that enters slide valve 4.Close slide valve 4.At last, rotation is hoisting gear 5 down, and the corrosion coupon of hanger bar 6 bottoms is sent in the oil pipeline.When taking out corrosion coupon, opposite with install operation process.The operating process of corrosion coupon being installed and taking out corrosion coupon does not influence the pipe laying operation.
The beneficial effects of the utility model: pressure pipe road corrosion coupon hanger in the utility model, not answer under the situation of the normal operation in speaking pipe road, safety, Fast Installation, taking-up low-pressure line detect uses corrosion coupon.In time get accurate basic data, the operation of grasp low pressure oil-gas pipeline dynamically, avoid because of the stopping production of installing, monitoring pipeline operation conditions is brought, get angry, workload such as dismounting large-sized flange, data manipulation labour intensity is got at the reduction scene, strengthens accuracy and validity that the pipeline operation detects.

Among the figure, 1. sealing gland, 2. steel pipe is 3. gone up hoisting gear, and 4. slide valve 5. descends hoisting gear, 6. hanger bar, 7. suppending hole.
Embodiment
Embodiment 1: with a middle pressure pipe road corrosion coupon hanger is example, and the utility model is described in further detail.
Consult Fig. 1.Pressure pipe road corrosion coupon hanger in the utility model is made up of sealing gland 1, steel pipe 2, last hoisting gear 3, slide valve 4, following hoisting gear 5 and hanger bar 6.The sealing gland 1 that has been threaded on the top of steel pipe 2, the outer wall of sealing gland 1 is symmetrically fixed with two cylinder bodily form handles.There is outer taper-thread the lower end of steel pipe 2, and the lower end of steel pipe 2 is connected with pipe adapter on the oil pipeline during use, the lower end of steel pipe 2 can with oil pipeline UNICOM.
At the hoisting gear 3 of being threaded from top to bottom on the steel pipe 2 on, a slide valve 4 and a following hoisting gear 5.A hanger bar 6 is arranged in steel pipe 2, on the wall of hanger bar 6, be processed with a tooth bar; A suppending hole 7 is arranged in the lower end of hanger bar 6.
What last hoisting gear 3 and following hoisting gear 5 adopted is the gear hoisting gear, in last hoisting gear 3 and the following hoisting gear 5 gear is arranged respectively, and gear is fixed on the end of axle, the tooth bar engagement of gear and hanger bar 6.The outer end of axle is connected with the handwheel of last hoisting gear 3 or following hoisting gear 5 outsides respectively, rotates handwheel and drives axle and gear rotation, and gear rotation kinetic energy promotes hanger bar 6.
