Designed for the oilfield, the Model 72 gate valve is the proven, reliable choice for applications requiring up to 5,000 psi working pressure and temperatures up to 250° F (121° C). The Model 72 gate valve is designed for maximum flexibility and reliability and is ideal for corrosive water flood applications, sour gas and crude oil service, as well as certain wellhead applications.
Oteco drill pipe float valves and baffle plates offer high quality single piece body construction for your every need. We offer our models in plunger or flapper style with automatic fill and pressure monitoring capability. Our seals are compatible for both standard and sour gas (H2S) service.
OTECO’s innovative bonded polyurethane piston dramatically extends service life in triplex mud pumps with ample water cooling. Harder, more dense polyurethane construction provides superior resistance to abrasive fluids providing optimum service life in harsh drilling conditions.
The OTECO premium stem guided valve and seat features an extra wide metal to metal seal on the valve flange. The serrated upper surface on the valve gives a longer non-breathing seal between valve body and insert while the rigid seat cross-arms give greater strength and positive sealing.
Oteco DM series fits the bill for low cost valve operation. Made from high strength weldable alloys and corrosion resistant components, this water, oil and gas gate valve provides ease of in-line repairs. The DM valve is offered with working pressure ratings up to 7,500 PSI (517 BAR), with standard or sour gas trim options, and 90 durometer main seals.
The OTECO Connector serves the same function as a high pressure flanged assembly. The hub element is the equivalent of a flange, the clamps serve the same purpose as flange bolts, and the seal ring acts as the pressure gasket. The OTECO connector is used in extreme conditions where corrosive or dangerous fluids and/or elevated or cryogenic temperatures are encountered.
OTECO manufactures shock pads for offshore rig jacking systems. Each pad is made with specially formulated rubber, molded between layers of corrosion resistant steel plates and is tested under load prior to shipment. This product is available upon request only and is custom manufactured to meet your specific requirements.
Oteco pressure gauges have a built in dampening mechanism to minimize wear and mechanical shock. In addition, the heavy duty seals restrict line fluid from entering the gauge mechanism. The gauge mechanism itself is surrounded by a special oil providing resistance to extreme temperatures, as well as vibration and shock.
The OTECO PRV (shear type) helps ensure protection for slush pumps, manifolds, and other expensive components used in drilling operations. The PRV utilizes shear pins to relieve overpressure during drilling and other operations. Hardened stainless steel stems and stainless steel liner subs provide improved corrosion resistance resulting in higher reliability and longer valve life.
The OTECO manual Reset Reset Relief Valve or RRV protects slush pumps and mud manifolds while guaranteeing greater safety in operation. The RRV automatically snaps to a full open position when the predetermined pressure is exceeded or can be manually opened by simply pressing the manual release button.
OTECO manufactures ten different styles of manifold fittings in 2 inch, 3 inch, 4 inch, and 5 inch with working pressures ranging from 3,000 psi to 7,500 psi with test pressures up to 11,250 psi. Each fitting can be supplied with either line pipe threads, or Schedule XX or 160 buttweld end connections.
OTECO manufactures wireline turnback assemblies and components. In addition, we have replacement rollers for the BJ model Roliguide. OTECO also offers complete wireline guide units and wireline guide hanging assemblies for most beam or angle type derricks. Additional information can be found in the Oteco Rig Hardware Product Brochure.
OTECO mud guards come in two models: the MG-600 and MG-800. Our mud guards have proven cost effective in saving the expense of lost drilling fluids, reduced labor for rig wash down, as well as reducing the potential for accidents due to slippery rig floors.
OTECO offers a complete line of forged steel impact box wrenches. Our size offering covers rig applications from 1-1/16 in. Nut/ 5-8 in. Stud to 3-7/8 in. Nut/2-1/2 in. Stud.
OTECO offers a quality line of Chain Conectors capable of handling chaing 1-1/4 to 4 Inches. See our Rig Hardware product Brochure for additional details.
Oteco provides replacement packing units and seals for the Hydril “GK”, “MSP”, Regan type “K” and the Shaffer Spherical blowout preventers. These items are available in Natural (NR), Nitrile (NBR) and Neoprene (CR) rubber compounds with each unit tested prior to shipment. In addition, Oteco offers replacement rubbers for the “Shaffer” rotating heads as well as Hinderliter stripper.
Oteco offers a wide range of pipe and Kelly wipers. These pipe wipers are offered in single, double, oval and handle bar types and are available in either natural (black) or oil resistant (red) nitrile rubber compounds. In addition, the double wipers are available in solid, split, and split rap-a-round configurations. Oteco pipe wipers offer greater tearing resistance due to a reinforced metal insert molded to the resilient rubber.
Oteco supplies replacement diaphragms and parts for the Hydril and Mattco 10 and 20 gallons pulsation dampeners. These diaphragms are molded in one piece and are available in 1,500 to 7,500 psi ratings. They also have a metal insert molded into the bottom to prevent extrusion into the bottom flange connection. Stabilizers, plates, screws, lock washers, bottom plate gaskets, charging valves and pressure gauges are also available.
Oteco balancing straps keep center-latch elevators balanced in any position. This makes elevators easier to handle, reducing fatigue. The balancing strap attaches to the link with a U-bolt assembly. The twisted metal loop at the other end of the balancing strap attaches to the elevator handle.
