STRAUB hose connectors Germany STRAUB models STRAUB prices

STRAUB hose connectors are components used to connect hoses to other hoses or components. Hoses include stainless steel hoses, metal hoses, corrugated hoses, rubber hoses, plastic hoses, and other types; hose connectors vary by type. Materials for metal hose connectors mainly include stainless steel, nickel-plated copper, and zinc alloy. Shapes mainly include external thread end connectors, external thread 45-degree elbows, external thread 90-degree elbows, internal thread connectors, self-locking connectors, and compression fittings, among others. Metal hose connectors can be selected based on installation conditions and operating environment.

STRAUB hose connector precautions

Bathroom water pipes generally run through the ceiling to reduce the risk of man-made damage. The interfaces and outlets of hot and cold pipes must be parallel, typically with the hot pipe on the left and the cold pipe on the right. During design, the entire pipeline should avoid bends as much as possible and be kept away from electrical circuits. The position and slope of pipe clamps must meet requirements. Each valve must be installed level to facilitate future use and maintenance. When installing hot water pipes, distinguish between the water heater inlet and outlet. Install a main valve at the inlet and connect the outlet to the bathroom piping. After installation, open the valve to check for leaks, then install the faucet and shower head in the bathroom. The bathroom is the darkest area in a home and prone to moisture accumulation, making ventilation critical. Ideally, a window should be designed into the bathroom. If this is not possible, to prevent mold and dampness issues, install an exhaust fan and avoid wrapping pipes. Many people tightly wrap bathroom pipes, which traps moisture inside and prevents it from dissipating, thereby increasing humidity in the bathroom.

STRAUB hose connector manufacturing process

Stamping forming: Stamping forming of elbows was the earliest forming process applied to 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 In the production of common specification elbows, it has been replaced by hot pushing or other forming processes.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 due to low production volumes, excessively thick or thin wall thicknesses, or special product requirements. Stamping forming of elbows uses pipe blanks with an outer diameter equal to that of the elbow, pressed directly into shape in a die using a press. Before stamping, the pipe blank is placed on the lower die, and the inner core and end die are inserted into the blank. The upper die moves downward to begin pressing, forming the elbow 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 forming, the outer arc of the stamped elbow is under tension, with no excess metal from other areas 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 stamped elbow process is often used for small-batch, thick-walled elbow manufacturing. Stamped elbows are divided into cold stamping and hot stamping; the choice depends on material properties and equipment capabilities. The cold extrusion forming process for 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 through 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 widely used for forming stainless steel elbows, especially thin-walled stainless steel elbows. This process requires high precision for the inner and outer dies and imposes strict requirements on the wall thickness deviation of the pipe blanks.

STRAUB hose connector precautions

When installing water pipe connectors, thoroughly remove all impurities from inside the pipes to prevent valve core damage, jamming, blockage, and leakage. Clean surfaces to ensure no construction material residues remain. For any type of residential water pipe connector, excessive force is not required during operation; gentle twisting or switching is sufficient. Even with traditional residential water pipe connectors, do not apply excessive force to tighten them. In particular, do not use the handle as a support or handrail. For products equipped with screen filters at the outlet, disassemble and rinse after a period of use to remove impurities. For products with hoses, ensure the hoses remain naturally extended to prevent breakage.
