Introduction to valve marking, packaging, storage and transportation
Valve markings, packaging, storage and transportation specific information is shown below.
1, the valve logo and identification paint should be in line with the provisions of JB106-59.
2, the product is not painted or no rust-proof layer on the processing surface must be coated with rust inhibitor, but the inner cavity must be coated with rust-proof paint.
3, in transport and storage, the gate valve gate and shut-off valve flap should be closed, the plug pathway should be fully open, the check valve flap should be closed and fixed. Both ends of the pathway should be closed firmly. Packaging of various products should be done in transport and storage without damage.
4, DN ≤ 40mm valves should be sent in boxes (or grill boxes).
5, the same batch of valve products should be accompanied by a packing list, product certification and product instructions, the specific contents of which are as follows:
Product Certificate of Conformity
(1) Product name, model and specification.
(2) nominal pressure, temperature and applicable media.
(3) Based on the standards and test conclusions.
(4) The date of inspection.
(5) Check the signature of the person responsible.
(1) Product name and nominal diameter.
(2) The number of products in each box.
(3) Gross weight per box (kg).
Product instruction manual
(1) Product performance and structure.
(2) valve use.
(3) the use of methods.
(4) Maintenance and storage.
6, the valve products should be kept in a dry room, do not allow open-air storage or stacking.
Nationalization is a trend, and there are some localization requirements in some projects. What are your experiences or views on control valve localization? There are actually more localization requirements involved in our work. We require designers to treat imported products and domestic products equally, unless for some special control valve products can not be manufactured in the country recommended the use of foreign brands, generally or domestic brand control valves. For special control valve products, generally in the engineering design, in order to produce a smooth start and operation of the device, the design will generally follow the views of the patent holder to choose a similar device in the use of performance, and in similar devices on the application of good valve products. About localization, now many direct users of the plant, taking into account the convenience of imported valve repair and maintenance, as well as cost factors, will choose some domestic manufacturers to provide inspection and maintenance services for imported valves, but also when the device used in the import control valve problems, in order not to affect production, in the rework waiting process, the use of domestic brand products as an emergency, once the product can cope with this working condition, the use of good Thus also test the reliability of the product, for the future in the same working conditions of the national brand valve application has laid the foundation. Now there are many enterprises that used to do valve maintenance, have accumulated experience in the practical application, the development of the valve production enterprises, to make a contribution to the localization of valves. For domestic valve manufacturers, how to win the trust of the owners is crucial. We now have many projects, are private entrepreneurs to invest in the construction of its cost control requirements are relatively high, the use of localized products in the project also accounts for most. Now many large state-owned enterprises construction projects, have the requirement of localization rate, which also creates a good environment for domestic products to replace imported brands, therefore, domestic enterprises as long as the strengthening of product quality standards requirements, strengthen the internal management of enterprises, continuous technological innovation, to provide good pre-sales and after-sales service, will be able to obtain the trust of the owners, so that the good development of enterprises.
in transport and storage, the gate valve gate and shut-off valve flap should be closed, the plug pathway should be fully open, the check valve flap should be closed and fixed. Both ends of the pathway should be closed firmly. Packaging of various products should be done in transport and storage without damage.
In July 2008, ARC Consulting Group senior analyst Mr. David Clayton (David Clayton) in the "Control Valve Worldwide Outlook" article: based on the rapid growth of the global control valve market in 2006, 2007 two years, forecast the next five years, the global control valve market will maintain a 6% compound annual growth rate. Control valve market will maintain a compound annual growth rate of 6%, based on 2007 global control valve market sales of $4.8 billion, by 2012, the global control valve market is expected to exceed $6.4 billion (Figure below).
Seismic brackets are used for a wide range of applications, including water supply and drainage for engineering buildings, natural heating and central air conditioning, electrical equipment, natural gas, fire safety, etc. Therefore, the engineering and construction regulations for seismic brackets will be more stringent.
Stainless steel ball valve has the function of heat preservation and cold preservation. Designed and manufactured according to national standards, petroleum, chemical, metallurgical and pharmaceutical industries are used according to 79-94 standards. Stainless steel ball valve adopts steam jacket insulation.
Seismic bracing manufacturer: Seismic bracing is a member or device that limits the displacement of mechanical and electrical engineering auxiliary facilities, controls the vibration of the facilities, and transfers the load to the load-bearing structure.
