Appl. No.:

8/604264

Inventors:

Douglas W. Carlson - Kingwood TX
Stephen P. Simons - Kingwood TX
William D. Breach - Kingwood TX

Assignee:

Hydril Company - Houston TX

International Classification:

F16J 1502

US Classification:

277188R

Abstract:

A high pressure seal material, such as for a lateral "T" seal of a shear ram blowout preventer, is disclosed wherein the seal material is preferably nitrile rubber and includes uniformly dispersed synthetic, non-cellulosic fibers in parallel alignment to resist rollover action occurring transverse to the applied compressive force by orienting the aligned fibers parallel to the axis of the applied force. The material is made in a milling process that aligns and maintains the alignment of the fibers. The milled sheet is then cut into appropriately shaped pieces. The pieces are rotated 90. degree. , plied and cured to make the final material, which curing can be done in a suitable mold so that the final product is in its desired final shape.

William D. Breach - Humble TX

Assignee:

Hydril Company - Houston TX

International Classification:

C09C 144

US Classification:

106475

Abstract:

An improved rubber stock with a unique carbon black system including mismatched pairs of furnace blacks with fumed silica and a silane coupler has been developed. The carbon black system includes a mixture of large and small particles with high and low structure carbon black pairs. The carbon black system compounded with polar and nonpolar rubber provides products with a range of desirable characteristics using only two carbon blacks.

Appl. No.:

6/808528

Inventors:

William D. Breach - Humble TX
Edwin W. Vaclavik - Houston TX

Assignee:

Hydril Company - Houston TX

International Classification:

C08K 304
C08K 513

US Classification:

524291

Abstract:

A composition for use in piping and pump systems for elevated temperature, steam and certain chemical resistant applications of ethylene-propylene copolymer with peroxide generated carbon to carbon crosslinkage. Effective amounts of antioxidants, carbon black, lubricant, thermal stabilizer and aid to peroxide crosslinkage is added. An antioxidant and thermal stabilizer system is used to produce a product with unusual thermal stability characteristics. The composition may also have a mixture of high and low particle size carbon black which acts as an antioxidant and reinforcing system. The composition may also use very fine particle carbon black for a highly elastic application. The composition can be used for rubber components which are exposed to a high temperature or to certain chemical environments, or where unusually high elasticity is required.

Assignee:

Hydril Company - Houston TX

International Classification:

C08K 300

US Classification:

524496

Abstract:

A carbon black system for manufacturing rubber comprises a pair of carbon blacks having the same structure, a fumed silica and a silane coupler. One of the pairs of carbon blacks has an Iodine Adsorption No. of less than 115 and the other pair of carbon blacks has an Iodine Adsorption No. of greater than 115. A rubber composition comprises a rubber selected from a group of polar and nonpolar rubbers, a carbon black system comprising a pair of furnace carbon blacks with both of the pairs of carbon blacks having the same structure, a fumed silica and silane coupler. One of the pairs of carbon blacks has an Iodine Adsorption No. of less than 115 and the other pair has an Iodine Adsorption No. of greater than 115. The carbon black system is from about 40 parts per hundred to about 80 parts per hundred of the rubber.

US Classification:

523220

Abstract:

A composition for use in geothermal or high temperature and steam applications of ethylene-propylene copolymer with peroxide generated carbon to carbon crosslinkage. Effective amounts of antioxidants, carbon black, lubricant, thermal stabilizer and aid to peroxide crosslinkage is added. An antioxidant and thermal stabilizer system is used to produce a product with unusual thermal stability characteristics. The composition also has a mixture of high and low particle size carbon black which act as an antioxidant and reinforcing system. The composition can be used for rubber components in geothermal drilling for pipe protectors, valve seals and other products which are exposed to a high temperature and steam saturated environment.

Filed:

Oct 20, 1988

Appl. No.:

7/262251

Inventors:

Douglas W. Carlson - Kingwood TX
William D. Breach - Humble TX

Assignee:

Hydril Company - Houston TX

International Classification:

C08K 501

US Classification:

524490

Abstract:

A rubber composition with small fluorocarbon micro-powder particles incorporated into the composition which reduces the coefficient of friction. The rubber with a lowered coefficient of friction allows for ease of movement of the rubber part against metal surfaces thereby reducing the wear of the rubber part.
