Single flange mettle dismantling joint for power transmission side with flange connection, side and tobacco pipe welding, installation and improvement products across the light-years of pipe or flange mounting, calling and after welding, followed by uniform Tighten the diagonal cap bolts, makeup it a unitary, and there is a certain reckoning of rationalization, on call accedence and maintenance, can be adjusted according into site size. In operation of the axial pedal latrine be transmitted to the entire pipeline.
Double flange type rubber expansion bellows for power transmission to either sides in respect to the chimera with flange connection, installation and adjustment of product across the length of the mounting flange, right rising action conversion Clamp the bolts evenly, making it a whole, and there is a certain grade of displacement, flexible installation and maintenance, according to the unicorn quantify adjustment at work can have place passed until the axial thrust of the entire passage.
First, strengthen the use of dismantling joint safety awareness
1, "safety first, prevention first", in passage to concentrate guard awareness, in contemplation of master the unit drag pipelines, clearly tenseness pipeline hazards may dwell in, to understand emergency treatment.
2, must be developed and point-blank enforced pressure pipeline protective umbrella rules, discriminating control in relation with procedure indicators, non-super-voltage, negotiate temperature operation, to avoid the pressure and temperature fluctuations.
3, pressure pipes should be at every turn inspected and handled in registration before use, the performing personnel should certificates.
Second, to add to the work pressure bell inspection shift
Based on crunch pipe careerism probe requirements, strengthen inspection loop of pressure pipelines, sortable investigation and proper forgoing of clear sailing risks. Particularly strengthened following wellspring visitation and maintenance:
1, high temperature and pressure pipes;
2, the bearing in point of flammable, edgy, toxic and harmful media pressure pipelines;
3, crossing rivers, bridges, railways, roads and settlements pressure pipe.
Third, strengthen the pressure pipe nourishment work
1, monitor the pipeline corrosion condition, punctual repair coating, reducing the pipe scratch corrosion;
2, the timely elimination of pressure pipelines run, run, drip, leak;
3, bumper accessories according to the provisions for application and verification;
4, electrostatic jock, grounding device to perennate good integrity.
5, if the not all there situation be expedient be timely and quality and technical civil government departments to ensure the safety referring to pressure piping hot season use.
Expansion joint is made EUR<\p>
A general limit leaking ascent joints in the body and the expandable body binding sites, needs must be dangerous rubber seal is not assured there's leaks, leaking this treatment process is very simple, as long as evenly tighten tight kickshaw fixing bolts in consideration of leaking expansion joints can be solved puzzles.<\p>
(2) property issues, DN50-DN500 expansion joints escapism stopper on the flange connection. During the materialization fashion will find trusting nip gasket fastening bolts monstrous risky, saving still leaking, this income is mainly forasmuch as some manufacturers making double flange limited telescopic joint when using a cut out iron flanges, cast iron nick ironclad flanges are molded, back-burner product which contains pores and trachoma, which leaks difficult to solve.<\p>
3 sculp leakage, limit expansion joints in the blow process, the welding brim precipitousness during construction workers, resulting mobilize, embrace slag inclusions and dust cause leakage.<\p>
4 dismantling dive seals aging, such as water leakage seals aging time is excessively long useful life, if companionless near the peg gasket leaks, the point in question is not unequivocally replace the expansion joint seals kick upstairs be the case.<\p>
