Method for sealing threaded pipe joints
View Patent ↗A material for sealing threaded pipe joints includes a multifilament yarn ready-coated with a joint sealing composition. The material is packaged in a dispenser from which the coated yarn may be supplied for direct application to a threaded area of a pipe.
1. A method for sealing a threaded assembly comprising:
providing a dispenser having a joint-sealing material packaged therein, wherein the joint-sealing material comprises a multifilament yarn and a joint-sealing composition ready coated over the yarn;
removing a portion of the joint-sealing material from the dispenser; and
applying the portion of the joint-sealing material to threads of a first threaded component of the threaded assembly.
2. The method of claim 1 , wherein the first threaded component is a threaded male component.
3. The method of claim 1 , wherein the first threaded component is a threaded pipe.
4. The method of claim 1 , further comprising:
providing a second threaded component; and
screwing the second threaded component over the threads of the first threaded component.
5. The method of claim 4 , wherein the second threaded component is a threaded female component.
6. The method of claim 1 , wherein the step of removing a portion of the joint-sealing material from the dispenser further comprises:
pulling the portion of the joint-sealing material through an aperture of the dispenser; and
closing the aperture with a closure means.
7. The method of claim 1 , further comprising the step of cutting the portion of the joint-sealing material to separate the portion from joint-sealing material remaining in the dispenser.
8. The method of claim 1 , wherein the joint-sealing composition is a non curing paste.
9. The method of claim 8 , wherein the joint-sealing composition comprises an oil and a filler, wherein the oil is selected from the group consisting of linseed oil, silicone oil, mineral oil, and combinations thereof.
10. The method of claim 8 , wherein the filler is a calcium carbonate filler.
11. The method of claim 8 , wherein the joint sealing composition has a viscosity from about 20,000 mPas to about 500,000 mPas.
12. The method of claim 1 , wherein the joint-sealing composition is a curable polymeric composition.
13. A method for sealing a threaded assembly comprising:
providing a dispenser having a joint-sealing material packaged therein, wherein the joint-sealing material comprises a multifilament yarn and a joint-sealing composition ready coated over the yarn;
removing a portion of the joint-sealing material from the dispenser; and
applying the portion of the joint-sealing material to threads of a first threaded component of the threaded assembly, wherein the joint-sealing composition is a curable polymeric composition that comprises a reactive monomer selected from the group consisting of a mono-functional acrylate ester, a poly-functional acrylate ester, a monofunctional methacrylate ester, a polyfunctional methacrylate ester and combinations thereof.
14. A method for sealing a threaded assembly comprising:
providing a dispenser having a joint-sealing material packaged therein, wherein the joint-sealing material comprises a multifilament yarn and a joint-sealing composition ready coated over the yarn;
removing a portion of the joint-sealing material from the dispenser; and
applying the portion of the joint-sealing material to threads of a first threaded component of the threaded assembly, wherein the joint-sealing composition comprises a hydroxyl-terminated polydimethyl siloxane and a filler.
15. The method of claim 12 , wherein the joint-sealing composition further includes a filler.
16. The method of claim 1 , wherein the yarn is a polyamide yarn or a polypropylene yarn.
