Petrochemical industry - Import export

For both onshore and offshore applications we develop technical heating solutions for the thermal treatment of gaseous and liquid media as well as for solids of all kinds.

These are the assembly parts of air valves.

Stainless steel flanges are a crucial component in various piping systems, providing ease of assembly and strength in connecting pipes, valves, pumps, and other equipment. They serve as a plate for covering or closing the end of a pipe and are commonly used in plumbing, oil and gas, petrochemical, and food industries due to their durability and corrosion resistance. Types and Specifications Stainless steel flanges come in several types to suit different applications: Weld Neck Flanges: Designed to be welded to the pipe. Suitable for high-pressure applications. Slip-On Flanges: Easily slide over the pipe and are welded in place. Socket Weld Flanges: Used for smaller, high-pressure piping. Threaded Flanges: Attached without welding, ideal for low-pressure applications or pipes with a thin wall. Blind Flanges: Used to seal the end of piping systems or pressure vessel openings. Lap Joint Flanges: Used with stub end fittings for applications requiring frequent dismantling.

Typical Fields of Application are in the chemical, petrochemical, railroad and shipbuilding industries, in the machine and industrial equipment construction. CSN® circulation heaters are manufactured in close coordination with our customers from a few watts to the megawatt range, a division in individual circuits is made according to customer’s requirements. Equipment for installation in hazardous areas we produce in protection class „Ex d“, „Ex de“, „Ex e“. On request, CSN® circulation heaters are supplied with optimized process controls. Please contact us to talk about the most appropriate control system. Schniewindt is certified by the Lloyd’s Register to produce equipment according to the Pressure Vessel Directive 2014/68/EU and a certificate from TÜV (Technical Monitoring Agency) certifies that we meet the prerequisites for welding procedures according to AD 2000 Merkblatt HP 0 / DIN EN 7293.

The LevelEx is available in sizes M16 to M63 or with NPT threads from 3/8" to 2 1/2". PFLITSCH manufactures the cable gland bodies from bright brass, galvanised nickel-plated brass and corrosion-free stainless steel. The LevelEx achieves protection class IP 66 or IP 68 and corresponds to the ignition protection types flameproof enclosure "Ex-d" and increased safety "Ex-e". With its wide temperature range of -60 °C to +130 °C and approvals according to ATEX and IECEx, the LevelEx can also be used under extreme environmental conditions. For armoured cables, PFLITSCH offers the LevelEX AC. It has the same technical quality as the proven LevelEx for non-armoured cables. In addition, it convinces with additional properties. For example, it scores with an innovative design for accommodating armoured cables: Two opposing windows in the armour clamping allow the correct seating of the cable armour to be checked immediately.

We develop and manufacture special seals for power stations, for the chemical and petrochemical industries, for machinery and pipeline construction. In other words, seals that provide the greatest possible reliability even under extreme operating conditions (pressure, heat, cold, aggressive media) – at temperatures from -200 to +1.000 °C. Product Range: - DVGW tested, see separate brochure - Punched, cut seals - Plates, foils - Semi-finished items - Form articles Benefits: - Highest chemical resistance - Insoluble and does not swell in organic or anorganic solvents - Resistant to the weather - Temperature range -190 to +250 °C - Highly anti-adhesive, does not stick - Resistant to hydrolysis Common fillers: - Quartz - Glass - Carbon / Graphite - Bronze - or without filters Fillers reduce the cold flow, lead to higher resistance to temperature and media, improve thermal conductivity and increase resistance to abrasion and pressure levels.

CHEMICAL & PETROCHEMICAL INDUSTRY

Combi decks are gratings with on top welded chequer plates. They combine ideally the advantages of both products. Chequer plates combine a closed surface with a slip-resistant effect. Gratings, on the other hand, have a high load capacity with a low tare weight. Lichtgitter-Combi deck is used for the industrial sector, e.g. chemical/petrochemical industry, power plants and cement industry as well as for bulk material and offshore applications.
