Abstract
The insulating anchoring short section is insulating anchoring equipment which is used for fixing and supporting in a steel pipeline system to play an insulating role, and solves the defects that the existing anchoring flange is not well insulated from the ground and is easy to corrode; sleeving a sleeve on a main pipe by using the insulation anchoring nipple, installing two reinforcing plates on the sleeve, installing four uniformly distributed fixing plates between the reinforcing plates, installing reinforcing rib plates between the outer surfaces of the reinforcing plates and the end heads of the sleeve, and coating a layer of solvent-free epoxy coating on the outer surfaces of the main pipe, the sleeve, the fixing plates, the reinforcing plates and the reinforcing rib plates; the steel pipe fixing support has the advantages of fixing support for the steel pipe system, insulating protection, and wide application in oil field, natural gas and water supply pipe systems.
Description
Technical field:
The invention is the improvement to the anchoring flange structure, is the insulation anchoring device that is used for the steel pipe system.
Background technique:
In the steel pipe system of oil field, rock gas, water supply; pipeline corrosion protection is all adopted the cathodic protection technology of sacrificial anode; and must be effectively controlled with the earth insulation in the pipe laying; in case being communicated with the earth, steel pipe certainly will produce potential difference; make the failure of cathodic protection technology, can not realize the corrosion protection of steel pipe.
At present; in the steel pipe construction, extensively adopt the anchoring piece of anchoring flange; this kind anchoring piece is through welded flange and baffle plate on pipeline; reach the anchoring pipeline with the canned one of concrete again; its shortcoming is that anchoring flange does not possess the insulating effect with the earth, is not suitable for the cathodic protection mode of steel pipe.
Summary of the invention:
The purpose of the invention provides a kind of pipeline that is used for and fixes, and increases support strength, realizes the insulation anchoring pipe nipple of cathodic protection and the earth insulation; The objective of the invention is to be achieved through the following technical solutions: insulation anchoring pipe nipple: it is characterized in that constituting by stiffening plate, non-solvent epoxy coating, deep floor, fixed plate, sleeve pipe, main body pipe; Casing pipe sleeve is contained in the main body tube outside, a stiffening plate is radially respectively installed at the place at the sleeve pipe two ends, between two stiffening plates, axially evenly distribute four fixed plates are installed, the end of corresponding fixed plate is installed deep floor respectively between stiffening plate outside and sleeve pipe termination, is coated with the non-solvent epoxy coating at the outer surface of main body pipe, sleeve pipe, fixed plate, deep floor.
The advantage of the invention: insulation anchoring pipe nipple; during use; be that main body pipe two ends and steel pipe are welded to connect; the anchoring pipe nipple that will insulate is fixed in the concrete; thereby pipeline has been realized the effect of fixed support; strengthen class, deep floor, fixed plate enhancing fixation; and can prevent that pipeline is fixed around axial commentaries on classics; because of its outer surface at insulation anchoring pipe nipple is coated with one deck non-solvent epoxy coating; play and the earth insulating effect; realize the effect of steel pipe cathodic protection, improve anti-corrosion capability.
Description of drawings:
Fig. 1 is an insulation anchoring pipe nipple plan view;
Fig. 2 is the side view of Fig. 1.
Embodiment:
Insulation anchoring pipe nipple: constitute by main body pipe 6, sleeve pipe 5, stiffening plate 1, fixed plate 4, deep floor 3, non-solvent epoxy coating 2; Casing pipe sleeve is contained on the main body pipe, a stiffening plate is respectively installed at the place at the sleeve pipe two ends, between two stiffening plates, evenly distribute four fixed plates are installed, in the outside of stiffening plate as shown in Figure 1 and four deep floors are installed respectively between the sleeve pipe termination, deep floor is corresponding with the fixed plate termination, at the main body pipe, sleeve pipe, fixed plate, stiffening plate, the outer surface of deep floor is coated with one deck non-solvent epoxy coating, in order to make the butt joint welding easy construction of main body tube and tube road, can not be coated with the non-solvent epoxy coating at place, main body pipe two ends, the non-solvent epoxy coating plays insulating effect, casing pipe sleeve is contained on the main body pipe, connect with welding manner, the installation of stiffening plate, fixed plate, welded and installed is all adopted in the installation of deep floor.
Claims (1)
