Circular sightglass fittings to DIN 28120 (PN 10, 16)Circular sightglass fittings similar to DIN 28120 (PN 6)DimensionsAssembly and construction materialsMounting

Our circular sightglass fittings to be welded into or onto vessel walls correspond in their construction and assembly to the dimensions and constructional guidelines of the DIN specification 28120. The respect of the DIN prescriptions for the flange thicknesses guarantees a distortion free location of the sightglass disc. The pressure resistance of the sightglass disc is, of course, dependent on the care with which the bolts and nuts are tightenend (always working on diametrically opposed pairs). For lubricated bolts, µ = 0.1, the recommended tightening torque values (in Nm) are indicated in the table below. The maximum operating temperature is limited to 150 °C when using sighglass discs of sodium silicate to DIN 8902 and to 280 °C when using sightglass discs of borosilicate to DIN 7080. This temperature is also function of the quality of the used gaskets. For operating temperatures lower than –10 °C, please consult the descriptive sheet AD 2000 W 10.

Mounting:After having correctly welded the base flange � onto or into the vessel wall, the gasket �, the glass disc �, the gasket � and the cover flange � are mounted one after the other and then the nuts � (in case of studded base flange �) progressively crosswise tightened against the studs �. The above indicated tightening torque values have to be strictly respected. Additional information may be taken from the DIN specification 28120.

Application:Elongated sightglasses VETROLUX® of the series LSG / LSGR / LSGRR may be used to observe the interior of reactors, columns, silos, vessels, storage tanks, pipelines or as liquid level indicators. They are delivered ready to be welded into or onto a vessel wall, complete with appropriate seals, glass plate and cover bolts. The D-end shape facilitates easier machining of the vessel wall prior to welding in the unit.Operating conditions:Nominal pressure 2,5 / 6 / 10 / 25 bar (see table overleaf)VacuumNote: The nominal pressure indicated refers to the design base of the sightglass. When welded into the vessel concerned, the base frame becomes part of the vessel wall. It is necessary, therefore, that appropriate strength calculations are made on all vessels concerned with respect to the design pressure and size of the vessel and in accordance with the relevant design code. If found to be necessary, reinforcement of the vessel wall has to be carried out.Operating temperatures:100 °C max. with sodium silicate glass to DIN 8903243 °C max. with borosilicate glass to DIN 7081Note: The above indicated temperatures refer to the use of unprotected glass plates, with no protective mica sheets.Standard materials:Base flange: Boiler plate RSt 37-2 / HII / AISI 316 Ti / AISI 316 LCover flange: Boiler plate RSt 37-2 / HII / AISI 304 / AISI 316 Ti / AISI 316 LGlass plates: Sodium silicate to DIN 8903(Transparent) Borosilicate to DIN 7081Seals: KLINGERsil C4400 EPDM Silicone PTFECover bolts Carbon steel, zinked, quality 8.8to DIN 912: Stainless steel A2-70Other materials on request.Certificates:To be supplied against extra charge to DIN EN 10204.Standard versions: (see left)- Base flange with bolt tappings drilled through (dimensions see table overleaf), type designation – DB- Base flange with blind tappings, type designation – SL- Base flange with radiused back (to correspond to vessel radius), type designation – ROptions:- Fluted glass plate for liquid level indication (only available for PN 25).- Special dimensions.- Closed back (base flange) version with drilled and tapped holes at the ends for pipe connections so that the unit may be used as an external gauge of a liquid level.Type designation:• Series LSG: Base and cover flange in boiler plate RSt 37-2• Series LSGR: Base flange in stainless steel Cover flange in boiler plate RSt 37-2• Series LSGRR: Base and cover flange in stainless steelOrdering example:For an elongated, D-ended sightglass of nominal pressure 10 with base and cover flange in AISI 316 / AISI 304 and the base flange in version b) with blind tappings together with a glass plate of sodium silicate to DIN 8903 and overall dimensions of 350 x 80 mm, seals PTFE base side, KLINGERsil C4400 cover side, cover bolts A2-70, the correct designation would be:1 piece type LSGRR 10-3, 1.4571 / SL - PTFE - 8903 - C4400 -1.4301 - A2.

Application:Rectangular VETROLUX® sightglasses of the series RSG / RSGR / RSGRR may be used to observe the interior of reactors, columns, silos, vessels, storage tanks and pipelines. They serve mainly as liquid level gauges. The are delivered ready to be welded into or onto a vessel wall, complete with the appropriate seals, glass plates, and cover fastenings.Operating conditions:Nominal pressure 16 barVacuumNote: The nominal pressure indicated refers to the design base of the sightglass. When welded into the vessel concerned, the base frame becomes part of the vessel wall. It is necessary, therefore, that appropriate strength calculations are made on all vessels concerned with respect to the design pressure and size of the vessel and in accordance with the relevant design code. If found to be necessary, reinforcement of the vessel wall has to be carried out.Operating temperatures:100 °C max. with sodium silicate glass to DIN 8903243 °C max. with borosilicate glass to DIN 7081Note: The above indicated temperatures refer to the use of unprotected glass plates, with no protective mica sheets.Standard materials:Base frame: RSt 37-2 or HII (boiler plate) / AISI 316 Ti stainless steelCover frame: As base frameGlass plate: Toughened sodium silicate glass to DIN 8903 (max. 100 °C) Toughened borosilicate glass to DIN 7081 (max. 243 °C)Gaskets: KLINGERsil C4400 / Neoprene PTFE / VitonCover fastenings: Steel, quality 8.8 / Stainless steelOther materials on request.Certificates:To be supplied against extra charge to DIN EN 10204.Options: - Version with closed base frame (drawing left) to be used as an external liquid level gauge with top and bottom pipe connections. For this application, the base frame will be supplied appropriately drilled and tapped.- Radiused base frame to suit vessel wall- Clear (transparent) glass plate- Alternative versions in shape and sizeRemarks:The TÜV approval does not apply to the base flange as this is considered as part of the vessel wall after welding. Standard delivery includes a reflex (fluted) glass plate. In circumstances where a clear (transparent) glass plate is required, this must be clearly stated at the time of enquiry.After welding into the vessel, the base frame should be checked to ensure that the sealing surface is flat and has not become distorted to avoid possible leakage under pressure and / or breakage of the glass plate during tightening of the cover frame bolts. This process should be carried out in several steps and progressively alternating between each pair of opposite bolts from one end of the frame to the other! Tighten first little, then repeat the operation.Type designation:• Series RSG: Base and cover frame in steel RSt 37-2• Series RSGR: Base frame in AISI 316 Ti and cover frame in RSt 37-2• Series RSGRR: Base and cover frame in AISI 316 TiOrdering example:1 piece rectangular sightglass, base frame in AISI 316 Ti, cover frame in RSt 37-2, length 350 mm, glass plate in sodium silicate glass to DIN 8903, fluted (Reflex), gasket product side PTFE, cover side Neoprene, cover fastenings 8.8 zinked:1 piece type RSGR-350, 1.4571 - PTFE - 8903 R - Neoprene - RSt 37-2 - 8.8 zink.

Survey of standard typesDimensions



Depending on the overall length of the sightglass, the cover frames are made to a maximum unit length A, and the base frame interrupted by bridges which correspond to this length. This strengthens the base frame and reduces the maximum length of the individual glass pieces required to cover the whole length, thus reducing the pos-sibility of glass breakages when the cover frames are tightened down. When selecting the overall length of the sightglass, and the number of units this will involve, due note should be taken to ensure that the liquid level to be observed normally falls into one of the visible sections. (If this is not possible, then consult us for our series of D-ended sightglasses LSG / LSGR / LSGRR)

Electrical motor drivefor use in hazardous areas for window wipers to be mounted on sightglasses, series WDE



R

Application:The staff of a plant does not always have the possibility to survey the interior of a process vessel through a sightglass on site. For these cases, remote observation by means of a camera linked to a control room is the optimal solution. A camera may, however, only record and transmit high-quality images if the product side of the sightglass disc is free of dust, condensate or crystal depots. The motor drive series WDE has been developed for such applications. The combination of a window wiper, a spraying device, a VIDEOLUX camera system and a light fitting from the broad MAX MÜLLER product range and the motor drive unit ensures an optimal image quality at any time.

Advantages:• Extremely compact dimensions• Low energy consumption• High torque• No maintenance required• High efficiency• To be mounted onto different sightglass types

Construction and scope of delivery:The motor drive consists of a DC motor � with directly flanged gearbox � and a special coupling �, with which the axis of the window wiper is driven.

Operating conditions:• Admitted for hazardous zones 1 and 2 as well as 21 and 22• For ambient temperatures from –20 °C to + 40 °C• Operating pressure of the unit sightglass / WDE: Depending on the dimensions of the sightglass disc with central bore hole

Introduction:Besides the well known wipers of the series W/WD which are – due to their construction principle – limited in their application since they withstand only weak pressure and/or vacuum, the wiper system WS permits to cover a wide spectrum of higher pressure and/or vacuum applications.

Application:Wipers of the series WS are used for the cleaning of the inner side of sightglasses built into pressure or vacuum vessels. They may be operated in hazardous as well as in safe areas. They fit by means of pressure and vacuum tight glands through the lower and cover flange of circular sightglass units to DIN 28120 or similar of DN 100 to 200.

Operating conditions:a) Maximum pressure: 16 bar b) Vacuum: Values on request c) Maximum operating temperatures: 180 °C with glass disSc to DIN 7080 (borosilicate) and wiper blade in silicone 200 °C with glass disc to DIN 7080 (borosilicate) and wiper blade in PTFE 150 °C with glass disc to DIN 8902 (sodium silicate)

Materials:Wiper mechanism: Stainless steel for all parts in contact with the product Wiper blade: PTFE or siliconeSealings: PTFE (admitted for use in food processing industries)

Possible combinations: The wiper system WS may be combined with a spraying device of the series SV/SVS as well as with the light fittings of the series CHEMLUX®, EdelLUX®, fibroLUX®, miniLUX® or metaLUX® for use in hazardous or safe areas. The light fittings may be mounted in the versions “light and view through one sightglass assembly” as well as for separate sightglasses.

Delivery:As a complete set with detailed mounting instructions to be built into existing sightglasses or supplied together with a complete sightglass VETROLUX® to your specifications. In the second case, MAX MÜLLER AG carries out the necessary machining of the welding and the cover flange of the sightglass.

AssemblyM o u n t i n gDimensions



The general assembly of the wiper system WS may be seen from the left drawing:The operating lever A with free-wheel return drives the wiper blade holder D in an uni-directional sense by means of a flexible shaft guided in the distance tube C. The tightness against pressure or vacuum is created by the gland sealings B.If the wiper system WS is mounted into an existing sightglass, we are supplying detailed and illustrated mounting instructions with the set. If the system is ordered with a VETROLUX® sightglass, the necessary adaptations are carried out in our works.For a correct delivery of the complete sightglass, we need the following order specifications:1. Nominal diameter (DN)2. Nominal pressure (PN)3. Materials for: a) Welding flange (e.g. 316 Ti =̂ 1.4571) b) Cover flange (e.g. carbon steel) c) Studs and nuts d) Sealings product side and cover side e) Glass disc (DIN 7080, borosilicate or DIN 8902, sodium silicate) f) Wiper blade (PTFE or silicone)
