MCC hose connectors Germany MCC models MCC prices

MCC hose connectors are high-quality flexible pipes used in modern industrial piping systems. They mainly consist of bellows, a wire braid, and fittings. The inner tube is a thin-walled stainless steel bellows with a spiral or annular shape. The wire braid on the outer layer of the bellows is woven from stainless steel wire or steel strip according to specific parameters. The fittings or flanges at both ends of the hose are matched to the fittings or flanges of the customer's pipeline. The bellows of the hose are formed by high-precision plastic working of ultra-thin-walled seamless or welded stainless steel pipes. Due to the elastic characteristics of the bellows profile, the hose exhibits good flexibility and fatigue resistance, allowing it to easily absorb cyclic loads from various motion deformations, especially providing the ability to compensate for large displacements in piping systems.

MCC hose connector functions

The function of a rotary joint is to serve as a sealing device that connects to input liquid from one side of a pipe into rotating or reciprocating equipment and discharge it from there. In the case of bent pipes, especially metal hoses, a considerable overall length is required for the stroke due to the large bending radius. By assembling a rotary joint at the root, it can be completed with the shortest hose length, which not only saves space but can also be used to absorb torsion in the hose depending on the method of use. Hydraulic and water piping systems using integrated rotary joints can also accommodate complex movements. They can be used with confidence in locations where hose installation is difficult or where significant leakage is a concern, as well as under severe environmental conditions such as high temperature and high pressure. For example, when a boiler burner is ignited, rotary joints assembled for inserting oil and steam piping can be used without problem even under severe conditions such as high temperature, high pressure, and complex movements. In summary, rotary joints can be equipped on cylindrical, drum-shaped, frustum-shaped, and spherical rotating equipment, as well as equipment that reciprocates or oscillates at any angle, using gases and liquids such as steam, water, oil, gas, air, brine, and ammonia for heating, drying, and cooling. They are also suitable for pneumatic and hydraulic equipment used for clamping, braking, and gripping.

MCC hose connector usage

How to ensure sealing in the connection between hose fittings and hoses? While connecting hose fittings to hoses is simple, ensuring a seal is critical. So, how is the seal achieved in the connection between hose fittings and hoses? Generally, regardless of the variety of hose fittings, the appropriate transition fitting must be selected based on the type of hose fitting. If the hose is a standard water hose, a transition fitting with one female thread end and one hose insert end should be used, secured with a hose clamp. If both ends of the hose have female threads, a transition fitting with one female thread and one male thread should be used. If both ends of the hose have male threads, a straight-through female-to-female transition fitting should be used. Most hydraulic quick-change couplings are designed for high pressure, so high-pressure hydraulic hoses are typically used. Since most hydraulic hoses have female threads at both ends, they can be connected directly. As for hydraulic fittings, no additional O-rings are needed for sealing; the product itself has one concave end and one convex end, achieving a complete seal upon connection.

MCC hose connector forming methods

Stamping forming of elbows was the earliest forming process applied to the mass production of seamless elbows. In the production of common specification elbows, it has been replaced by hot pushing or other forming processes. However, it is still used for certain elbow specifications where production quantities are low, wall thicknesses are excessively thick or thin, or when products have special requirements. Stamping forming of elbows uses pipe blanks with an outer diameter equal to that of the elbow, and a press is used to directly form them in a die. Before stamping, the pipe blank is placed on the lower die, and the inner mandrel and end die are inserted into the blank. The upper die moves downward to start pressing, and the elbow is formed through the constraint of the outer die and the support of the inner die. Compared with the hot pushing process, the surface quality of stamping forming is inferior. During the forming of stamped elbows, the outer arc is in a stretched state, and there is no excess metal from other parts to compensate, so the wall thickness at the outer arc is reduced by approximately 10%. However, due to its suitability for single-piece production and low cost, the stamping elbow process is often used for small-batch, thick-walled elbow manufacturing. Stamped elbows are divided into cold stamping and hot stamping, and the choice between cold or hot stamping is usually made based on material properties and equipment capabilities. The forming process for cold-extruded elbows uses a dedicated elbow forming machine. The pipe blank is placed in the outer die, and after the upper and lower dies close, the blank moves along the gap reserved between the inner and outer dies under the push of a push rod to complete the forming process. Elbows manufactured using the inner and outer die cold extrusion process have an attractive appearance, uniform wall thickness, and small dimensional deviations. Therefore, this process is often used for forming stainless steel elbows, especially thin-walled stainless steel elbows. This process requires high precision for the inner and outer dies and has strict requirements for the wall thickness deviation of the pipe blanks. Medium plate welding involves using a press to form half of the elbow profile from medium plates, and then welding the two profiles together. This process is generally used to manufacture elbows larger than DN700.
