We manufacture three kinds of marine hydraulic steering gears. They're oscillating oil cylinder type, reciprocating shifting fork type and rotary vane type. They can be used in all kinds of ships. We use high quality import sealed devices in steering gears. Pressureresisting, wearresisting and leaktightness are their merits. The chrom-plated surface of piston rod or plunger use particular technology, so the wear-resisting ability and corrosion protection is perfect. We optimize the design of rudder tiller, shifting fork and support, so they have reasonable construction and high hardness. The function of hydraulic-electric control system is perfect and it has much protection to prohibit the circumstance of overload and miss position of rudder. You have many options to the arrangement of control board. All the products meet the classification survey from major Classes like CCS, ABS, BV, DNV, NK, LR, GL. The regular hydraulic steering gears are divided to five series: 1. FDYD manpower hydraulic steering gear 2. ZRD aided force manpower hydraulic steering gear 3. SDY oscillating oil type hydraulic steering gear 4. DYD oscillating oil type hydraulic steering gear 5. WYD back and forth type hydraulic steering gear

Y piece(Tee) is a three hole, namely an inlet and two outlet; or two inlets, a kind of chemical pipe outlet, there are T-shaped and Y-shaped, with equal diameter nozzle, orifice diameter pipe also, for three identical or different line Survey Office. The main role tee is to change the direction of flow.
Divided by technology
1. hydroforming
Tee hydroforming is compensated by the axial expansion of the metal material of a Branch Pipe forming process. The process is the use of special hydraulic machine, the injection of the liquid and the inner diameter equal to the three-way tube, side cylinder synchronous movement of the extruded tube by two horizontal hydraulic presses, tube after extrusion by the smaller size, the inner tube the volume of liquid with the smaller tube and pressure rise, when it reaches the three-way manifold pressure required for the expansion, the metal material in the dual role of the cylinder and the inner tube side fluid pressure and flow along the mold cavity bulge manifold.
Tee hydroforming process can be a shape, high production efficiency; competent and shoulder tee wall thickness were increased.
Due to the larger seamless tee hydroforming process equipment required tonnage currently mainly for the manufacture of standard wall thickness less than DN400 tee. Its application for the molding material is relatively low work hardening tendency of low-carbon steel, low alloy steel, stainless steel, including some non-ferrous materials, such as copper, aluminum, and titanium.
2. thermoforming
Thermoforming tee tee is greater than the diameter of the tube, flattening about to tee diameter size,
Drawing links
Stretching branch site to open a hole; tube by heating, into the forming die, and a tensile load manifold die within a tube; tube is radially compressed under pressure, radial compression during the metal flow direction and forming the manifold branch pipe in a stretched punch. The whole process is by radial compression and stretching process tube manifold portion is shaped. Tee hydraulic bulging difference is that hot tee branch pipe metal tube is carried out by radial motion compensation, it is also known as radial compensation process.
Because after pressing tee by heating the material forming the equipment needed to reduce the tonnage. Hot links to wider adaptability of materials suitable for low-carbon steel, alloy steel, stainless steel material; especially large diameter and wall thickness bias tee, often use this forming process.
