We are supplying welding and cutting items and gases particularly intended to meet the most noteworthy gauges of the overall marine industry and to perform under the most thorough shipboard conditions.
Security is dependably a prime thought. From the spout blending outline of our slicing connection to the prescribed flashback arrestors and reverse discharge valves, no welder ought to be without. All items are intended to perform securely and dependably under the hardest states of shipboard utilize and bolstered with parts and administration through Dubichem Marine International in every significant port all through the world.
Acetylene
Dubichem Marine International acknowledges no duty regarding non-standard cylinders being arrived without earlier assent in composing. Dubichem Marine International will give typical barrel support including intermittent hydrostatic assessment and recertification and substitution of worn best valves at no cost to the ship proprietor. The repair of any harms caused by abuse or despicable taking care of by the client or missing valve security tops will be charged to the record of the ship proprietor. Drew Marine won't acknowledge for credit cylinders which have been subjected to bend consume, fire, fire or effect bringing about imprints or gouges.
Acetylene A-40 General Description
The Acetylene and Oxygen Distribution System gives the gas supply to the cutting/brazing applications locally available vessels.
The Acetylene and Oxygen cylinders with chamber valves, T-valves, shutting valves and focal controllers might be arranged in isolated store on or over the upper constant deck with the cylinders put in an erect position and the controllers secured with wellbeing valves ventilated to outdoors. The outlet station is typically set in the motor room or in the workshop. On extraordinary reason ships, it might be put on open deck.
Highlights
Colourless and somewhat lighter than air
It is non-poisonous yet has a soporific impact if breathed in
Acetylene is very combustible
When blended with oxygen for welding, the fire temperature will achieve 3100º C
Safeguard and Information for clients/Owners
Staying away from impacts which could harm either the shell and additionally permeable material;
Shutting valves on purge cylinders;
Keeping up the leftover weight inside the barrel;
Denying transfilling of cylinders;
Staying away from drenching in water
Encouraging not to conceal harm to cylinders that could, for instance, have been submerged or harmed, e.g. by repainting, and;
Putting away purge cylinders in committed territories with the valves shut.
Technical
Acetylene blended with air is unstable inside 2.2% to 85% by volume. Abstain from discharging acetylene into the air and guarantee great ventilation where acetylene cylinders are put away or utilized.
At the point when acetylene cylinders are transported evenly and set vertically again after transport, a time of no less than 24 hours before utilizing the cylinders for gas extraction must be complied.
This to guarantee that the CH3)2CO inside the chamber redistributes effectively. At the point when cylinders are utilized too rapidly subsequent to setting them vertical again the accompanying can happen:
When opening the best valve, a lot of CH3)2CO can turn out. The client may decipher this as water/oil since CH3)2CO feels elusive on the skin. Opening the best valve without a fitted controller ought not be standard practice as this can make a fire peril.
At the point when a controller is fitted with twin hose and light, the lit fire will be exceptionally unsteady because of the nearness of CH3)2CO beads in the gas. This is regularly alluded to as "spitting".
The arrangement is to give the chamber a chance to rest for no less than 24 hours (contingent upon temperature; colder condition may require longer time).
Tare "A" weight of acetylene cylinders incorporates barrel shell, neckring, valve, permeable mass and CH3)2CO. For acetylene the accompanying is legitimate:
1 nm3 = 1.095 kg
1 kg = 0.91 nm3
1 bar = 14.5 psi
1 nm3 = 35.3 ft3
1 kg = 2.2 lbs
