Gas cylinder Process

Selection of high quality raw materials

SEFIC introduces advanced equipment, technical standards and quality management system and carries out strict production operation and quality inspection actively so that each team has accurate task and clear responsibility. We also have implemented strict complete quality and security control system, which ensures that each gas cylinder can meet the quality and security requirement of our customers.

Pipe inspection and blanking

There are detailed and long-term records and reports of work stress, internal stress, strength, ductility, hardness, toughness and other mechanical properties and machinability properties, malleability, castability, weldability and thermal expansion, magnetic, electrical and other physical and technological properties of raw material.

Heat shrinkage bottom and bottle mouth

Heat shrinkage bottom and bottle mouth directly affects the qualified rate of the late cylinder, cylinder operator need to carefully fill in the bottle wall thickness, and the appearance, manufacturing tolerance and original records, such as data and bottom anatomy test report single, closing and collected at the end of the monitoring records to facilitate later product quality tracking.

Heat treatment

First preheating, the test ring above the specimen captured test, then the cylinder body is put into the thermal aging furnace heat treatment, to gradually eliminate the stress of steel cylinder body, cylinder visual inspection after the heat treatment of the cylinder, scrapped the deformation, cracking and brittle fracture of the cylinder.

Shelve to relieving of internal stress

SEFIC engineers believe that heat treatment is the most important to eliminate internal stress, but only by heat treatment to eliminate internal stress is not enough, to the extent to reduce the use of hidden dangers in the latter part of the cylinder after the heat treatment, the cylinder in the factory to use 15-20 days, to use natural aging to eliminate residual stress.

Mouth processing and Internal flushing

In the late use of gas cylinder, gas contains trace oil, gas bottle valve or cylinder after the use of non - off valve side of the bottle, so that the acid, alkali, combustible or other impurities fall into the bottle, will lead to the corrosion of gas cylinder, so that the body of the cylinder is very important to clean and dry.

Weighing and testing the mechanical properties

Mechanical gas cylinder, hardness, and the degree of linear correlation detection and tensile test, impact test and flattening test, the unqualified gas cylinders do recording, isolation, processing, such as the case of batch unqualified cylinders, cause analysis is carried out to find the problem, and timely credited to the steel bottle archives.

Hydraulic test

We change gas cylinder hydraulic pressure measured method in bottle test conditions, and the computer control technology, overcome the pressure gas cylinder closed beta test were affected by the experimental conditions affecting the shortcomings of, so as to improve the measurement accuracy, to fit the conditions of mass production.

Install bottleneck and internal drying

Completed after water pressure test cylinders must immediately remove the internal cylinder of water drained, through the cylinder internal dry device for drying operation, to avoid the cylinder internal rusting and impact on the quality of the products, thus affecting subsequent inspection. So the cylinder drying is an important part of the process of production and inspection.

Install valve and gas leakage test

Will fill the tank with the provisions of the pressure gas tank, so that any part of the cylinder from the surface minimum depth greater than 5cm, to check the gas tightness, through the mechanical slowly rotating cylinders, observe the wall of the bottle is no bubble, such as found in the gas bubble or bubble, then need to sort out.

Stamped and Install cap

The gas cylinder seal has two parts: gas cylinder manufacture seal and gas cylinder inspection stamp. Making seal includes gas filling name, serial numbers of the cylinders, experimental pressure, working pressure, the weight of the cylinders, cylinder volume, the bottle design wall thickness, production time, etc.; the inspection stamp including unit test code and test date.

Shot blasting and derusting

Shot blasting is not only in order to remove the surface oxide skin and sand casting, and also to check the quality of the casting before an indispensable preparation procedure, shot blasting can also increase the dislocation structure, to improve the strength and fatigue strength of cylinder body has a important significance, and the spray paint technology to prepare.

Paint and drying

Paint can in the cylinder surface to form protective film, can prevent or delay of cylinders by prolonged exposure under the water, microorganism erosion caused by metal corrosion, can also use color to mark the bottle of gas, for electrical insulation, anti fouling, anti resistance, heat insulation, radiation resistance, conductive, magnetic etc. also has a certain role.

Finished product inspection

Every batch of gas cylinders (200 pieces as one batch normally) are manufactured and tested under supervision of local special equipment inspection and research institute and then issued batch test report.Of course,each finished gas cylinder before delivery to customers has to pass leakage test to ensure no leakage occurs.

Spray word or Printing

According to customer requirements, SEFIC to spray the surface of the printing cylinder customers need to text, it can play the difference between a logo and brand promotion of the role of complete, customers can design their own spraying the contents of the cylinder surface, of course, SEFIC also be free for you design.

Random inspection

Random sampling is an important part of quality control cylinders, inspector through observation, measurement, test and judge, a conformity assessment carried out on the upcoming cylinders manufactured, and quality inspection of product quality inspection agency can invite to plant for testing, or after the invitation to the customs inspection agency to customs to detect.

Packaging

The gas cylinder usually packed by pallets, wrapped by pvc, also can use the bulk loading , if you have other requirement of the package of the gas cylinder, we also can do it as your required! We are always packaging the gas cylinders carefully, and we will be responsible for each gas cylinder, you can rest assured to cooperate with us!

Declare to customs

SEFIC is an integrated company which designs, manufactures, sales and services in the pressure vessel field, We have CE, TPED, TUV, etc. on the pressure cylinder production and sales certificate, can be directly through the freight forwarding customs procedures, so far, sefic had serviced more than 60 countries clients.

Attached to the container cabinet

Usually SEFIC contact forwarder to pull the container to the SEFIC plant, and then carry out the cylinder loading. If the gas cylinders packed by pallet, it’s easy to load them into the container and unload them from the container. If you need to bulk, we can also do it, but we don't normally recommend doing so, this may in the transport process may damage to the cylinder of paint.

Delivery

Once we receive your purchase order and deposit money, we will be reviewed and arrange for production as soon as possible, we are committed to producing better gas cylinders and services, and to inform you that inspection, after inspection, we will give the contract agreement your delivery, Please note the check and give us a single receipt......
