Description
Technical field
The present invention relates to the high strength that a kind of deep water pipe laying tensioner frictional resistance piece is used
-high friction resistance composite material and preparation method thereof.
Background technology
Submerged pipeline is the important component part that deep water hydrocarbon field Development Engineering is built, and pipeline layer is unique heavy construction equipment that submarine pipeline is laid.Stretcher is one of topmost equipment on pipeline layer, is to clamp weld and through the pipeline of coating protection and control under it and put into extra large specific equipment, require it can realize permanent tension control.And frictional resistance piece (being commonly called as cushion block) just on stretcher directly and the parts of tube contacts; its effect is that the snap-in force on crawler belt is evenly distributed on pipe; produce larger friction resistance, to clamp pipe or to drag pipeline, and avoid tube surface protective layer physical abuse.Meanwhile, marine pipe laying barge is standing the effect of wind, wave, tide at any time, and it is upper and lower, the irregular concussion of left and right can cause the irregular, inhomogeneous stressed of pipeline and clamping device (frictional resistance piece), and this just requires frictional resistance piece to have very good serviceability.
Deep water pipe laying tensioner frictional resistance piece need meet the performance of following 4 aspects:
1) high strength
When stretcher is in running order, every frictional resistance piece approximately bears the operating pressure of 30 tons, and frictional resistance piece and pipeline be in relative movement state, and this just requires frictional resistance piece to have high resistance to compression and shear strength.
2) the high coefficient of friction resistance
Because marine pipe laying barge is standing the effect of wind, wave, tide at any time, it is upper and lower, the irregular concussion of left and right can cause the irregular, inhomogeneous stressed of pipeline and clamping device (frictional resistance piece).Therefore, frictional resistance piece and pipe surface have the key that high frictional resistance (friction) coefficient is the effective work of assurance stretcher and safe construction.If the coefficient of friction resistance is not enough or it is larger to change, once cause pipeline slippage and cause work safety accident, its financial loss is difficult to the appraisal.
3) suitable hardness
Because frictional resistance piece directly contacts with pipeline and both are in relative movement state.Frictional resistance piece hardness is excessive, can pipeline and protective layer generation thereof firmly be weighed wounded or be scratched, and even causes piping failure; Hardness is too small, and the abrasion loss of equipment frictional resistance piece in service will increase, thereby causes frictional resistance piece life cycle to shorten, and not only increases use cost, and frequently changing frictional resistance piece also can affect construction speed, reduces production efficiency.
4) suitable plastic deformation ability and elasticity
Suitable plastic deformation ability and elasticity are to prevent restorable basis after frictional resistance piece generation brittle rupture and viscous deformation.Plastic deformation ability is too poor, and frictional resistance piece is easy to, when suddenly stressed or stress distribution is inhomogeneous, brittle fracture occurs, and jeopardizes stretcher operating safety; Elasticity is too little, once frictional resistance piece generation stress deformation, it cannot recover its original state, thereby affects the goodness of fit that contacts of frictional resistance piece and pipeline, and then reduces the working efficiency of stretcher.Plastic deformation ability and elasticity are too strong, and stretcher is applied to frictional resistance piece upward pressure and is easy to lose or produce larger fluctuation by plastic deformation and changes, thereby reduce the enclasping force of frictional resistance piece to pipeline, easily cause pipeline slippage.
The stretcher frictional resistance piece that deep-sea pipeline layer uses at present mainly relies on import, and its material mainly contains rubber-based and elastic polyurethane base two classes.And the maximum coefficient of friction resistance under 30 tons of positive pressures that single frictional resistance piece applies at stretcher is about 0.12, and maximum tension power is about 3.7 tons.Calculate like this, be applicable to the tensile force that pipelines in deep sea lays and be the stretcher of 500 tons to the maximum, need to approximately 135 frictional resistance pieces being together in series and working simultaneously just can meet the demands.The length that these frictional resistance pieces are together in series is about 34m (calculating by 0.02 m gap between each frictional resistance block length 0.23m, every), make the volume of whole stretcher very huge, not only improved equipment manufacturing cost, also taken space on a large amount of ships, and on existing stretcher, be only provided with 54 frictional resistance piece installation sites, with domestic and international existing frictional resistance piece, cannot meet stretcher operating pressure is the condition of 500 tons at all.Therefore, improve single frictional resistance piece maximum tension power and become the key addressing the above problem.But due to the restriction of the clamping radial loading that can bear by tube wall, the positive pressure that stretcher applies frictional resistance piece can not improve again.Therefore the coefficient of friction resistance that, improves single frictional resistance piece becomes the unique channel that improves single frictional resistance piece tensile force.In recent years, external many enterprises (comprising the world-famous enterprises such as Italian Remacut company, U.S. Westech company, Dutch SAS Gouda company) and domestic lappingout Suo Deng unit have carried out correlative study for this problem, although have made some progress, effect is remarkable not.Therefore, research and develop a kind of novel high-strength-high friction resistance composite material and make frictional resistance piece, not only can effectively alleviate the urgent need of deep water pipeline layer stretcher to high frictional resistance (large tensile force) frictional resistance piece, can promote technological transformation and the upgrading of pipe laying tensioner simultaneously, for the development of domestic and international deep water pipeline layer stretcher industry etc., all there is promoter action.
