How Winter Affects Your Car’s Undercarriage

Winter is here, and with it comes the usual suspects: snow, ice, and slippery roads. Most drivers know to be cautious when driving in these conditions, but there's another hidden danger that often goes unnoticed—rock salt. While it helps keep roads safer by melting ice, it can also wreak havoc on your car’s undercarriage over time. Rock salt is commonly used by municipalities to treat roads during winter storms. It works by lowering the freezing point of water, which prevents ice from forming and helps melt existing ice. However, as vehicles drive over these treated roads, the salt gets kicked up and sticks to the bottom of cars. This is especially problematic in regions like the Northeast, where heavy snowfall and frequent road treatments are common. What many people don’t realize is that the undercarriage of a car is particularly vulnerable to corrosion. Unlike the body of the vehicle, which is usually painted and protected, the undercarriage is exposed to the elements. Over time, rock salt can cause rust, scratches, and damage to critical components such as the exhaust system, suspension, brake lines, and more. To protect your car from this hidden threat, it’s important to take proactive steps. One effective way is to have your vehicle waxed, including the undercarriage, to create a protective barrier. You can also use oil-based pretreatments that prevent salt and moisture from sticking directly to metal surfaces. Regular washing is another essential step. Many car washes offer high-pressure sprays that can help remove accumulated salt from the undercarriage. And before the winter season begins, it’s a good idea to get a pre-winter inspection to address any issues before they worsen. If you’re looking for expert care to keep your car safe through the winter months, consider reaching out to DaSilva’s Auto Body. From detailing to inspections and repairs, their team can help you prepare your vehicle for the challenges ahead. Don’t wait until it’s too late—schedule your winter maintenance today and enjoy peace of mind all season long.

Drilling Rig and Workover Rig

The drilling equipment consists of eight systems: lifting system, rotating system, circulating system, transmission system, driving system, control system, drilling rig base and auxiliary equipment. Drilling equipment is divided into rotation, lifting, circulation, power and transmission, control and other systems according to function:

1. The main equipment of the rotary system is the Rotary Table installed on the wellhead of the drill floor. During rotation, the drill string and bit are driven to rotate and drill through the Kelly. When the downhole power drilling tool is used to drive the bit to rotate, the rotary table is used to bear the reverse torque.

2. The hoisting system is a set of hoisting equipment composed of winch, derrick, crown block, traveling block, hook, steel Wire Rope , etc. The winch is mainly used to trip the drilling tool, run the casing and control the WOB during drilling. The derrick is used for placing crown block, hanging traveling block, hook and other lifting equipment and tools, as well as lifting and storing pipe string. The crown block and traveling block are a set of complex pulley device to reduce the tension on the winch wire rope. The number of wire ropes of the complex pulley of large and medium-sized drilling rigs is generally 8 ~ 12 strands.

3. The mud circulating system is composed of Mud Pump , high-pressure mud pipeline, water hose, faucet, drill string and mud Solid Control Equipment.

4. Solid control equipment is used to remove useless solid particles in the mud returned from the well. The commonly used equipment includes vibrating screen, Desander , Desilter , degasser and centrifugal separator. In the late 1970s, the automatic mud preparation system began to be used in combination with the well control device, which can reliably control the wellbore at any time and automatically keep the mud specific gravity constant. In case of blowout omen, it can automatically adjust the mud specific gravity and other properties.

5. Power and transmission system includes power machine and transmission unit. The power engine mainly uses diesel engine, motor or gas turbine. The transmission unit includes mechanical transmission such as chain, belt and gear, hydraulic transmission and electric transmission to transmit power to working machines such as winch, rotary table and mud pump.

6. The control system enables each unit to work coordinately according to the needs of drilling technology. It includes the control of starting, stopping, speed regulating, paralleling and reversing of power machine, winch, rotary table and mud pump. The methods include mechanical, pneumatic, hydraulic and electric control, and develop in the direction of electronic computer control.

7. Well control equipment is an important equipment used to ensure safe drilling in oil and gas drilling, including BOP, Choke Manifold, kill manifold, Mud Gas Separator, etc. The blowout preventer is used to prevent the blowout of mud, oil, gas and water in the well. The blowout preventer includes ram blowout preventer, rotary blowout preventer and universal blowout preventer. It is installed at the wellhead under the drill floor and is used to close the annular gap between the drill string and casing or all wellhead respectively. In addition, there is a blowout preventer in the drill string, which is used to close the internal space of the drill string. Modern drilling equipment is equipped with several sets of different types of BOP to form wellhead BOP group to control different drilling conditions.
