Pružné vedenie a spojovacie príruby

Konštrukčné diely v chemickom priemysle, napr. diely odlučovačov a výmenníkov tepla, diely pre papierenský priemysel, ťažbu ropy a zemného plynu, kompresory a pre odsoľovanie morskej vody.

Konštrukčné diely, na ktoré pôsobí morská voda, napr. výmenníky tepla, dopravné alebo vstrekovacie čerpadlá, hriadele vrtúľ, vysoko namáhané diely v chemických a odvodňovacích zariadeniach a na dopravu ropy a zemného plynu (napr. rozvodné diely), odlučovače, lopatky turbín a ventilátorov, komponenty nízkotlakových kompresorov.

Pre konštrukčné diely veľmi zaťažené chemickou koróziou, napr. zariadenia chladené morskou vodou a na morských vrtných plošinách. V oblastiach chemického priemyslu, kde pri vyšších tlakoch a teplotách dochádza k zaťaženiu v čistých kyselinách ako aj v kyselinách s obsahom chlóru (hlavne kyselina sírová), organických kyselinách a zmesiach kyselín. V dôsledku zvýšenej odolnosti voči štrbinovej korózii je možné použitie aj všade tam, kde sa počíta s tvorbou povlaku, resp. kde sa nedá konštrukčnými opatreniami zabrániť štrbinám.

H500 – Žiaruvzdorná oceľ

BÖHLERL718 API (UNS N07718) is a high-strength, corrosion-resistant nickel-chromium-iron-molybdenum material with excellent corrosion resistance, especially in H2S and CO2 environments. The alloy is age-hardenable due to the addition of niobium, titanium and aluminium. BÖHLER L718 API is recognised by the oil industry for its simple and cost-effective production in combination with good tensile, fatigue, creep and fracture strength and is used in a wide range of applications in this sector. BÖHLER L718 API has excellent weldability and is resistant to cracking after welding. The material can be used at high temperatures. BÖHLER L718 API is available in the NACE/API 6A CRA versions with a minimum yield strength of 120/140 ksi and also in the high-strength version with 150 ksi. All hardness grades are suitable for sour service and can be used for pressurising and pressure-controlling equipment in corrosive environments. Typical applications include packers, pumps, connectors and fasteners as well as gate valves, throttle spindles, pipework hangers and fire safe valves, but also a wide range of downhole and completion components, nuclear and surface applications.

P511 – Nenamagnetizovateľná oceľ

BÖHLER P513 is a weldable, non-magnetic, austenitic stainless steel with resistance to seawater and intercrystalline corrosion. It offers the best abrasion resistance of all stainless steels. The corrosion resistance of BÖHLER P513 is better than that of conventional austenitic Cr-Ni steels (type 304), and even better than Cr-Ni-Mo steel (type 316) under standard test conditions against chloride pitting, stress corrosion cracking and crevice corrosion. BÖHLER P513 is an alloy with a high silicon and manganese content and added nitrogen, which also works well at high temperatures around 1800 ºF. Silicon and manganese prevent wear and scuffing even in the annealed condition. Higher strengths can be achieved by cold forming, but this does not significantly improve abrasion resistance. BÖHLER P513 is used in the aerospace, food and pharmaceutical, oilfield, petrochemical, surgical and chemical industries, e.g. for valve stems and valve seats, fastening systems, shielding, chain drive systems, pins, bushings and roller bearings, wear rings and pistons in pumps.
