STAUFF hose connectors Germany STAUFF models STAUFF prices

STAUFF hose connectors are high-quality flexible pipelines in modern industrial piping systems. They mainly consist of bellows, braided mesh, and fittings. The inner tube is a thin-walled stainless steel bellows with a spiral or annular shape. The outer braided mesh 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 match the fittings or flanges of the customer's pipeline. The bellows of the hose are formed by high-precision plastic processing of ultra-thin-walled seamless or welded stainless steel pipes. Due to the elastic characteristics of the bellows profile, the hose has good flexibility and fatigue resistance, making it easy to absorb cyclic loads from various motion deformations, especially compensating for large displacements in piping systems.

STAUFF hose connector differences

Difference between external water pipe fittings and union fittings: Unions connect pipelines; quick-install fittings have one end connecting to the pipeline and the other to a hose for easy material discharge, and can be covered with a cap when not in use. When installing water pipe fittings, first understand the components of the water pipe fitting. Components include: elbows, reducing elbows, internal/external thread elbows, tees, reducing tees, internal thread fittings, reducing internal thread fittings, external thread fittings, internal/external thread fittings (bushings), caps, plugs, unions, etc. If choosing PPR pipes, weld them using a heat fusion machine; if using iron pipes, thread them first with a threading machine, then wrap with hemp or PTFE tape.

STAUFF hose connector material classification

1. Austenitic stainless steel: The matrix is primarily austenitic structure (γ phase) with face-centered cubic lattice, non-magnetic, mainly strengthened by cold working (which may induce some magnetism). 2. Austenitic-ferritic (duplex) stainless steel: The matrix contains both austenitic and ferritic phases (the minor phase content is generally greater than 15%), magnetic, and can be strengthened by cold working. 3. Ferritic stainless steel: The matrix is primarily ferritic structure (α phase) with body-centered cubic lattice, magnetic, generally cannot be hardened by heat treatment, but can be slightly strengthened by cold working. 4. Martensitic stainless steel: The matrix is martensitic structure, magnetic, and its mechanical properties can be adjusted by heat treatment. 5. Precipitation-hardening stainless steel: The matrix is austenitic or martensitic structure, and can be hardened (strengthened) by precipitation hardening (also known as age hardening). 6. Stainless steel: 1Cr18Ni9Ti 0Cr18Ni9 00Cr19Ni10 0Cr17Ni12Mo2Ti 00Cr17Ni14Mo2 304 304L 316 316L etc. 3, stainless steel elbows have certain corrosion resistance (oxidizing acids, organic acids, cavitation), heat resistance, and wear resistance. They are commonly used in power plants, chemical industry, petroleum, and other equipment materials. Stainless steel elbows have poor weldability; attention should be paid to welding processes, heat treatment conditions, and selection of suitable welding electrodes.

STAUFF hose connector composition

What is a stainless steel ferrule fitting? A stainless steel ferrule fitting is a component that provides reliable connections, featuring high pressure resistance, temperature resistance, and good sealing performance. It is used across industrial, commercial, and residential applications to ensure operational safety. As market demand for stainless steel ferrule fittings continues to grow, these versatile products are increasingly utilized in various sectors. A ferrule tube fitting consists of three parts: the fitting body, the ferrule, and the nut. When the ferrule and nut are placed on the steel tube and inserted into the fitting body, tightening the nut causes the outer front end of the ferrule to seat against the conical surface of the fitting body, while the inner cutting edge uniformly bites into the seamless steel tube, forming an effective seal. Ferrule fittings are characterized by corrosion resistance, high pressure tolerance, simple installation, and durability.
