Description
Technical field
The present invention relates to pipeline construction fields, more particularly to a kind of structure for pressure test of pipe fitting.
Background technique
Oil drilling platform tends to a kind of special ocean manufacturing equipment, and hydraulic stainless steel tube requirement used is very high, greatly
Part pipeline all uses butt welding linked vector graph, therefore one of critical process in pipeline construction, as inspection pipeline welding quality
One of with the main means of tubing, mainly whether verifying welding quality and pipeline material quality, pressure-bearing range meet design
It is required that and discovered whether unsafe other factors, be that in-pipe inspection robot runs preceding one of critical process.
According to classification society rule, after butt welded tube is prefabricated in workshop internal field, as flanged pipe, 1.5 times of designs need to be carried out
The pressure testing of pressure examines weldquality.Due to the difference of caliber, difference, the pressure rating of material are different, existing docking
Welded tube structure for pressure test safety coefficient is lower.
Existing butt welded tube structure for pressure test has following defect：（1）Safety is poor, and old technology uses Norma's pipe jointer,
Tooling is done with this attachment, after many pipelines are connected together with the attachment, carries out pressure testing.Due to no effectively practical fixed
Device may cause during pressure testing with the raising of pressure, and attachment is shaken off from pipeline, only correctly fixed, ability
Ensure construction personnel's safety, it is ensured that entire pressure testing construction safety；（2）Material and labor hour are wasted, old technology is using welding one
Part tool part, this technique is pipe to be done to long 50mm, and weld the tool part of a part of pipeline addition orchid in end, then by institute
There is piping connection similar with flange pipe pressure testing, after pressure testing, sends entire pipeline back to workshop for extra pipe tooling
It is seen off after part polishing, polishing zinc-plated；（3）Pressure testing is inefficient, can not protect when connecting because of butt welded tube subport with connector
Hold has different degrees of tilt angle on the same line, causes not can guarantee uniform force when screwde on, and when pressure testing connects
Locate leak, needing to adjust connector repeatedly just can guarantee leakproofness, pressure testing inefficiency, and the time of weld seam is pressure testing at pressure testing one
3 times of the time of a pair of of flange；（4）Operating instruction is cumbersome, and pipeline pressure test belongs to high-risk operation.In pipeline pressure test construction,
If not being very strict about rules, the details of safe construction is not focused on, the style of work is not rigorous, what these often caused the accident
Immediate cause.Pressure testing equipment is arrived greatly, and small to one piece flange plate screw only carries out safety operation in strict accordance with operating instruction,
It can ensure that construction personnel's safety, it is ensured that entire pressure testing construction safety.
