Description
Technical field the utility model relates to a kind of former that is applicable to the modified glass steel lining multiple tube of carrying fluid media (medium) or similar applications that is used to produce.
The background technology U.S. has developed frp lining multiple tube technology in the eighties of last century sixties, and it is to have caused a sensation oil circle in outstanding antiseptic property and strange long service life.Started a technological revolution in water injection well in oil fields engineering field.Its technical characterictic is the corresponding bushing pipe that design has barrier propterty in common steel tube (can be referred to as basic pipe), in the circumferential weld between basic pipe and bushing pipe, bonding packed layer is set.China's expert advice is introduced this technology, and the not transferring technology and the U.S. only does a joint venture causes imported technology not realize.In order to capture this technology, my labor the investigation data, consulted the relevant expert, and, carried out the development more than 2 years and tackled key problems in conjunction with the actual conditions in China oil field, succeeded in developing in the modified glass steel of new generation in May, 1998 and claimed multiple tube.Realized surmounting on U.S.'s frp lining pipe performance filled up domestic blank.Its basic technical features is: realized that fully the disposable of basic pipe and internal lining pipe connect airtight, make internal lining pipe on basic pipe once moulding become possibility.And successfully developed the former that this cover is used to produce modified glass steel lining multiple tube in 1999, make modified glass steel lining multiple tube technology formally move towards the extensive finished product production phase, the scientific research technology is converted into productivity by laboratory stage, sample stage, sample amplification stage.
Summary of the invention goal of the invention of the present utility model be design a kind of practical, simple and easy rationally, the former of modified glass steel lining multiple tube that practicality and operability are all very strong, meet the specification requirement of the technical characterictic and the modified glass steel lining multiple tube of modified glass steel lining multiple tube fully, and the central various standard technology requirements to conveyance conduit of realistic application.Therefore the utility model must fully satisfy following condition, just can be considered to rationally feasible:
First: satisfy core requirement.It is the basic technical features of modified glass steel lining multiple tube.The essential characteristic of modified glass steel lining multiple tube is: adopt glass fabric, glass mat to soak into the compound remodeling fiberglass of making in back as liner with vinylite; Remodeling fiberglass uses the core expanding mould tool on the special special equipment directly to push to expand in recombination process and is attached on the inwall of basic pipe.The glass fabric that is adopted is the glass fabric of edge sealing; Glass mat is the glass mat that contains the silks silk.Therefore former key problem to be solved must center on composite material tape (soaked into resin after glass fabric, glass mat) and the expansion of core expanding mould tool.
(one) is about the problem of composite material tape.
1) modified glass steel lining multiple tube employing glass fabric (can be described as glass cloth) and glass mat (can be described as the glass felt) are basic liner material strip, and these two kinds of stock quality softnesses are banded.And the basic technical features of modified glass steel lining multiple tube requires: production tube must guarantee that bushing pipe cooperates tight, concordant, seamless with basic pipe end face.That is to say, before the composite material tape that glass cloth, glass felt form after soaking into resin is entering basic pipe, the cylindrical body of necessary formation rule, interlayer skew, fold and interlayer fissure of displacement phenomenon can not appear, otherwise can bring visual defects such as undergauge, bulge, bubble, crack, can't reach pipeline and carry the technological requirement of liquid modified glass steel lining multiple tube.Former must satisfy the restriction of above factor with reasonable method.
2) the soaking paste plumpness of glass cloth and glass felt, uniformity problem.Resin is a kind of fluid that is thick easy curing, glass cloth is after having soaked into resin, certainly exist the problem of an absorption saturation degree, after glass cloth reaches the absorption saturation degree, if unsettled motion, the phenomenon of weeping appears in the resin that must make extension be attached to the surface, scrape off the unnecessary resin of composite belt surface so must design corresponding device thereof, save material on the one hand, the more important thing is to prevent because caliber variation and phenomenon such as rough appear in the inhomogeneous internal lining pipe that causes final molding of the resin of composite material tape absorption.Simultaneously, this has also retrained composite material tape and finally how to have presented realization thinking cylindraceous.Consider according to convention, composite material tape under driving, horizontal drag force is moved with the complete keeping parallelism of basic body cross section, directly be attached to core expanding mould tool surface and can guarantee the formation of composite material tape rule cylindrical body, but because the restriction of raw material characteristics, this thinking is infeasible.Its consequence is not only to cause die surface to adhere to a large amount of resins to bring extra removing work, and is bound to bring in the walking process of composite material tape in basic pipe, because the problem of accumulation, fold and the fissure of displacement appears in the friction of tube wall.
Two) about the problem of core expanding mould tool:
1) the core expanding mould tool plays 2 effects in the forming process of modified glass steel lining multiple tube:
1 〉: the end of composite material tape is bundled in the joint area of core expanding mould tool, utilizes the butt joint locking mechanism on core expanding mould tool joint area and the hauling machine bar that composite material tape is drawn in the basic pipe, and with basic pipe justify align
2 〉: utilize the good expansion character in core expanding mould tool inflation back that composite material tape is directly pushed to expand and be attached to the inwall of basic pipe.But find two problems in sample: one, the core expanding mould tool directly contacts with composite material tape, can make a large amount of resins of core expanding mould tool surface contamination; Two, the smoothness deficiency on core expanding mould tool surface is so that reach the requirement of inner wall smooth after the internal lining pipe moulding.So in forming process, must protect the core expanding mould tool on the one hand, strengthen the smooth effect of moulding inside pipe wall on the other hand at the uniform and smooth film of the surface of core expanding mould tool parcel one deck.And the design of former also must realize the good location of core expanding mould tool, and the geometric centre axes of core expanding mould tool, hauling machine bar, composite material tape is overlapped fully, so just can guarantee composite material tape non-migration, dislocation after entering basic body fully.
Second: satisfy specification requirement.The specification requirement of modified glass steel lining multiple tube is:
1) bushing pipe cooperates tight, concordant, seamless with basic pipe end face.
2) the internal lining pipe inwall is smooth, smooth, visual defects such as no bulge, no bubble, free from flaw, no marking.
The the 3rd: satisfy the standard technology requirement.Promptly satisfy under various fluid media (medium)s of carrying by pipeline or even the abominable fluid media (medium) environment (as water injection well in oil fields) to the requirement of conveyance conduit.Comprise:
1) internal diameter of the modified glass steel lining multiple tube of Sheng Chaning is very little, does not influence the test job of normal water injection well or conveyance conduit;
2) carry the fluid media (medium) performance good, inner-walls of duct is smooth.
The 4th: satisfy the large-scale production needs, the production efficiency height, operating cost is low, and is simple and easy reasonable, and stronger practicality and operability are arranged.
