Steel grinding balls are used in mining, coal, cement and other industries in the mechanisms of ball mills, performing the function of grinding bodies.
We offer:
Grinding Balls (Forged, Cast, Chromium)
Grinding balls are used for grinding ferrous and non-ferrous metal ores, cement clinker, refractories, minerals, ceramics, coal, slag, construction and other materials in ball mills.
The durability of steel grinding balls is largely determined by the properties of the steel used to make them. At the same time, the operating conditions of the grinding balls impose mutually exclusive requirements on them: high hardness, wear resistance and impact strength.
Cast iron grinding balls with a high chromium content are used in cement and mining industries.
Welded, Seamless Metal Pipes
Electrowelded pipe - a sample with one seam extending along the entire length, made of sheet metal or strips by molding or welding.
Rolled metal is divided into 4 types: longitudinal, spiral, water and gas, profile.
Seamless pipe is a one-piece metal construction with no connection types.
HDPE polyethylene pipes are used for laying pressure and non-pressure pipelines transporting water, including for domestic and drinking water supply, at a temperature of the transported liquid from 0 to 40 ° C, for pressure sewer communications and gas distribution systems, as well as other liquid and gaseous substances, to which polyethylene is chemically resistant.
HDPE pipes are designed exclusively for underground laying, they are produced in coils of 100, 200 meters and in sections of 12, 13 meters. At present, almost all work on the repair of dilapidated and construction of new water pipelines, laying of new gas networks is carried out exclusively with pipes made of low-pressure polyethylene.
Plastic HDPE pipes advantages:
Flanges and elbows, gate valves and tees are part of the piping design. They make it possible to change the direction of pipe laying, to add a new branch to the construction.
Each of these parts has its own purpose.
Transitions, elbows, tees can be used to change the direction of water, technical liquids or gas. They also help change from one pipe diameter to another.
Elbows are made of steel, steel with increased corrosion and cold resistance, alloy steel.
Bends are subdivided into:
Shut-off pipeline fittings hermetically shut off or completely open the flow of the working medium in the pipeline. The main types of shut-off pipeline fittings are taps, gate valves, valves, dampers and butterfly valves. Shutoff pipeline valves also include drain and control pipeline valves.
Drainage valves are used to discharge the working medium from pipeline systems and various tanks, and control valves are used to supply the working medium to instrumentation and control instrumentation.
Regulating pipeline fittings regulate the parameters and flows of the working medium in the pipeline. Depending on the parameters of regulating the working medium in the pipeline, the control pipeline fittings are designed to regulate the flow of the working medium, regulate the medium pressure and liquid level, as well as mixing various media. The main types of control pipeline valves are gate valve and a shut-off and control valve, a mixing valve, a pressure regulator and a level regulator, control ball valves and control valves. Pipeline fittings are used to reduce the operating pressure in the pipeline, and shut-off and control valves are used both to shut off and to regulate the flows of the working medium in the pipeline.
