Flowlines and connectors require BÖHLER steels with high strength and corrosion resistance. Key quality features include ultra-clean materials, full traceability, controlled heat treatment, and rigorous testing for reliable oil and gas performance
Flowlines and connectors in the oil and gas industry are critical components used for the safe transport of hydrocarbons under demanding conditions such as high pressures, temperature fluctuations, and exposure to corrosive media including CO₂, H₂S, and seawater. These components must withstand dynamic loading, external stresses, and aggressive environments over extended service periods. Material requirements are therefore focused on high strength, excellent toughness, resistance to corrosion and stress corrosion cracking, as well as reliable performance under fatigue and pressure cycling. In subsea and offshore applications, additional resistance to hydrogen embrittlement and low-temperature toughness is essential.
BÖHLER high-performance steels and alloys are specifically engineered to meet these demanding conditions. Advanced quenched and tempered steels, corrosion-resistant alloy (CRA) grades, and high-alloyed steels provide an optimized balance of strength, durability, and resistance to aggressive media. Produced using advanced melting and refining technologies, BÖHLER materials ensure superior cleanliness, low inclusion content, and homogeneous microstructures, significantly improving reliability and service life. Key quality features include strict chemical composition control, certified traceability, and precisely controlled heat treatment processes tailored to application requirements. Comprehensive testing, including corrosion resistance, fatigue behavior, and non-destructive inspection, ensures compliance with stringent oil and gas standards. BÖHLER materials enable safe, efficient, and long-lasting flowline and connector solutions.

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.

Prečítajte si viacBÖHLERL718 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.

Prečítajte si viacBÖHLER 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.
