The State Police Report quoted a refrigeration serviceman who reported that all of the valves on the evaporator were shut off and the fire chief found a steam hose steaming underneath the machine.

The State Police report quoted a refrigeration serviceman who reported that all of the valves on the evaporator were shutoff and the fire chief found a steam hose steaming underneath the machine. The serviceman had previously seen steam used to melt ice buildup around the valves and to heat the oil in the machine to make it easier to drain the oil. [ 51 The District Engineering Inspector s report confirmed that the machine was completely isolated and the ammonia system was not protected by a safety valve or any type of pressure-relief device. The cause of the accident was the presence of the steam ho.se underneath the equipment to melt the ice on the drain valve or to help evacuate the system. The inspector s report could not determine if these preparations were intentional or accidental. 151...

An external source of dry, acid-free butane was routed to the depropanizer via a mbber hose. Steam was lined up to the tower s reboilers, and the reflux pump started to maintain level in the reflux drum (this is called putting a tower on total reflux). 

EPDM rubber preferred for a great number of specific applications. For many years peroxide-cured EPDM based compounds have been applied, e.g., for window seals, automotive hoses, steam hoses, conveyer belts, roof sheeting, tank lining, roll coverings, mouldings, and last but not least, for electrical insulation and jacketing compounds. Two formulation types (403) are illustrated in Tables 33 and 34.

Extrusion. Extmsion techniques are used in the preparation of tubing, hose, O-ring cord, preforms and shaped gaskets. Typical extmsion conditions are 70 to 85°C for the barrel temperature and 95 to 110°C for the head temperature. The extmded forms are normally cured in a steam autoclave at 150 to 165°C. Some special grades of peroxide curable fluorocarbon elastomers can be hot air vulcanized. 

PTFE is used for lining chutes and coating other metal objects where low coefficients of friction or non-adhesive characteristics are required. Because of its excellent flexing resistance, inner linings made from dispersion polymer are used in flexible steam hose. A variety of mouldings are used in aircraft and missiles and also in other applications where use at elevated temperatures is required. 

The hose was used for a service such as steam or nitrogen, and the service valve was closed before the process valve. As a result, process materials entered the hose. 

The steam valve at the other end of the hose was closed just before the column inlet valve, thus allowing process material to enter the hose. The operators knew this was not normal practice. 

But they closed the steam valve first because they knew the hose was damaged and wanted to avoid subjecting it to the full steam pressure.

Butyl ruhher vulcanizates have tensile strengths up to 2,000 psi, and are characterized hy low permeahility to air and a high resistance to many chemicals and to oxidation. These properties make it a suitable rubber for the production of tire inner tubes and inner liners of tubeless tires. The major use of butyl rubber is for inner tubes. Other uses include wire and cable insulation, steam hoses, mechanical goods, and adhesives. Chlorinated butyl is a low molecular weight polymer used as an adhesive and a sealant. 

A pressure vessel constructed of steel, used for the vulcanisation of rubber products by the open steam method. The autoclave may be horizontal (vulcanisation of footwear, cables, hose), or vertical and fitted with a hydraulic ram (e.g., moulding pneumatic tyres). 

M17 Lightweight Decontamination System (LDS) The M17 is a portable pump and water-heating unit for producing hot water and steam. The system incorporates a 1,580-gallon collapsible water tank, two wand assemblies, connecting hoses, and a shower rail. It is issued to Army battalion-size units and to chemical decontamination companies and battalions. 

A heat penetration study dehning load cool points is not limited to load conhgurations composed of liquid-hlled vials. The same principles can be applied to process equipment loads (hlters, hoses, etc.) subject to steam sterilization. Penetration thermocouples are positioned at points within the process equipment suspected to be the most difficult for steam heat penetration. Temperature data are obtained from representative maximum and minimum loads in order to establish temperature prohles... 

The purpose is to qualify the sterilization cycle of the A-ml vial filling machine parts, filtration assembly, and hose pipes in steam sterilizer... 

Another phenomenon associated with a crude oil fire is stopover. Basically, die same principles that are responsible for a boilover are the cause of a stopover. The fundamental difference is that in a stopover the reaction is from water that has entered the tank since the start of the fire. Usually this introduction is die result of firefighting activities. A slopover will occur at some point after the heat wave lias been formed. Eidier the water from the hose streams or, after the bubbles collapse, the water in the foam will sink into the oil, contacting the heat wave, where it is converted to steam, and die agitation of the liquid surface spills some amount of oil over the tank rim.
