Abstract
A device for suspending a corrosion coupon for a low-pressure pipeline is applied for the anti-corrosion coupon test of an oil field pipeline. A gate valve is fixed in the middle of a steel pipe; an emptying screwed plug is fixed on the steel pipe; a sealed cavity is formed at the top of the steel pipe; a seal packing is arranged in the sealed cavity; an internal thread is arranged at the top of the sealed cavity; a seal gland is fixed at the top of the sealed cavity through a screw thread; a center hole is formed in the seal gland; a cylindrical suspension rod penetrates through the seal gland and the seal packing; a support is fixed at the top of the steel pipe; a top plate is fixed at the top of the support; a center screw hole is formed in the top plate; a screw rod is arranged in the center screw hole of the top plate; the top of the screw rod takes the shape of a hexagonal prism, and the lower end of the screw rod is connected with the top end of the suspension rod. The utility model has the benefits that on the condition that the normal operation of the pipeline is guaranteed, a corrosion coupon used for testing a low-pressure pipeline can be mounted and withdrawn safely and fast, further, the labor intensity of on-site material taking operation is reduced, and the accuracy and validity of the pipeline operation test can be enhanced.
Description
Technical field
The utility model relates to oil field pipe conveying technology field, and the device of particularly a kind of pipeline corrosion protection test is oil, feed channel is lower than the device that low pressure pipeline that 1.6MPa, temperature be lower than 100 ℃ hangs corrosion coupon at operating pressure.
Background technique
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 running 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 running medium at any time to Corrosion of Pipeline.
The model utility content
The purpose of this utility model is: a kind of low pressure pipeline corrosion coupon suspension arrangement is provided, detect pipeline internal medium to the wall erosion situation at realizing in the pipeline running, 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: low pressure pipeline corrosion coupon suspension arrangement, mainly form by top board, screw rod, support, sealing gland, sealed packing, steel pipe, VENT PLUG, boom stick and gate valve, be fixed with gate valve at the steel pipe middle part, the lower end of steel pipe can be welded on the crude oil pipeline.It is characterized in that: screw is arranged on steel pipe walls, a VENT PLUG is arranged at the screw internal fixation.Seal cage is arranged at the top at steel pipe, and sealed packing is arranged in Seal cage, at the top of Seal cage internal thread is arranged, and is fixed with sealing gland at the top of Seal cage by screw thread.Sealing gland has center hole, and cylindrical boom stick is passed sealing gland and sealed packing.Roof anchorage at steel pipe has support, and the roof anchorage of support has top board, and top board has center screw, and a screw rod is arranged in the top board center screw; The top of screw rod is the hexagonal prism body, can use the spanner rotating screw bolt.The lower end of screw rod connects the top of boom stick.
The using process of summary low pressure pipeline corrosion coupon suspension arrangement.Consult Fig. 1.At first, boom stick 8 is passed sealing gland 4 and sealed packing 5, hung lacing film 11 in the lower end of boom stick 8, under the closed condition of gate valve 9, boom stick 8 is inserted in the steel pipe 6, screwing hermetic gland 4 makes sealed packing 5 sealings; Tighten VENT PLUG 7.Secondly, support 3 is fixed on the top of steel pipe 6.Screw rod 2 lower ends are connected with boom stick 8 tops.Then, open bottom gate valve 9, be communicated with pipeline 10, last, the back drives boom stick 8 by rotary screw 2 and lacing film 11 moves down, and corrosion coupon 11 is sent to position in the predetermined pipeline 10, the test of beginning lacing film.Remove top top board 1, screw rod 2 and support 3.
When taking out lacing film 11, install top top board 1, screw rod 2 and support 3.Screw rod 2 is connected with boom stick 8 tops, and rotary screw 2 is closed gate valve 9 with the top of corrosion coupon 11 proposition gate valves 9; Open VENT PLUG 7 pressure releases, sealing gland 4 and sealed packing 5 are pulled down together with boom stick 8, lacing film 11 integral body, detect the corrosion situation of corrosion coupon 11.
The beneficial effects of the utility model: the utility model low pressure pipeline corrosion coupon suspension arrangement, not answer under the situation of the normal operation in speaking pipe road, safety, quick mounting, 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 labor intensity is got at the reduction scene, strengthens accuracy and validity that the pipeline operation detects.
