The size/dimensions/price of PVC Duct-Product from China Sourcing

The Details of PVC Duct:

PVC duct pipe is constructed of rigid polyvinyl chloride and is often the most cost effective ductwork material of choice. Benefits of using PVC (plastic) duct for your fume, exhaust and drain jobs include: lightweight design, easy to install system, works with negative and positive pressure applications, high resistance to chemicals and corrosion, and high tensile strength.

Industrial PVC duct is a popular alternative to metal duct and offers impressive corrosion resistance that other materials do not. Plus, PVC is surprisingly low maintenance and doesn’t rust or scale. PVC duct fittings come in a range of styles and sizes like all our PVC fittings.These fittings bridge the connection from one section of pipe to another in a straight run of duct.

The Function of Duct Pipe?

Corrosion resistant PVC duct pipe products are used for exhaust ventilation systems in commercial and industrial settings. PVC duct reduces the amount of power consumption and also creates a maintenance free system. It achieves this by being corrosion-resistant and self-insulate. PVC duct pipe can be used both in concrete encased and direct burial applications. It is also ideal for suspended applications involving pipe supports or pipe hangers.

What Is The Best Way To cutting plate?

1.Oxy-Fuel Cutting

Oxy-fuel torch cutting, or flame cutting, is by far the oldest cutting process that can be used on mild steel. It is generally viewed as a simple process, and the equipment and consumables are relatively inexpensive.

2.Plasma Cutting

Plasma arc cutting is a great process for cutting mild steel plate, offering much higher speeds than oxy-fuel cutting, but sacrificing some edge quality.

3.Laser Cutting

The laser cutting process is suitable for cutting mild steel from gauge thickness up to about 1.25 inch. Beyond the 1 inch barrier, everything has to be just right to make it work reliably, including the material (laser grade steel), gas purity, nozzle condition, and beam quality.

4.Waterjet Cutting

Waterjet cutting also does a very nice job of cutting mild steel, giving a smooth and extremely accurate cut. Waterjet cuttingaccuracy can exceed that of laser cutting, because the edge smoothness can be better, and there is no heat distortion.

This is basically the same process that is used to mint coins. Sometimes the part of the machinery (the “forcer”) that forced the planchet into the die was used to impart markings to the back of the badge; these markings could be in relief (standing up from the surrounding material, produced during the stamping process), incuse relief (markings standing up from a surrounding lowered area, usually square or rectangular (Balfour used this on some of their wings) or incised (stamped into the wings).

How to be a good China agent?

What a good China agent do?

They are a necessary buffer zone, the thing that keeps the industry separate from the art. It is entirely possible, of course, that agents themselves can be exploitative – and the right terms are not necessarily the same as the best possible terms.

What is the standard agent process?

I’d say that the standard procurement process should look something like this:
1.) Confirmation of product specifications and certification requirements
2.) Supplier sourcing
3.) Initial price research, sample order and selection of qualified suppliers
4.) Initial price negotiation
5.) Audit of qualified suppliers
6.) Final supplier selection
7.) Sales Agreement
8.) Production and Quality Control
9.) Shipping

The questions a agent should be answered:

Apart from having a pre-determined purchasing and procurement process in place, your agent shall be able to give straight answers the following questions:
1.) On what factors do they deem a supplier to be qualified / not qualified?
2.) Will you pay the purchasing agent for the products or pay directly to the supplier?
3.) What’s their strategy on preventing and countering frauds? (I.e. Payment frauds)
4.) Will they manage the whole purchasing process ”in house” or outsource parts of it? (If yes, which parts?)
5.) How is the agent prepared to deal with potential quality issues during and after production?
6.) How long have they been established?
7.) Will they send the inquiry to an already ”tested” supplier or source a new supplier?
8.) Do they have any buyer references from your country? (Never work with a purchasingagent who refuse to provide you with buyer references)

Why choose China Sourcing?

China Sourcing has many years experience in goods inspection, improve the qualified rate, increases product quality for you, most of our products qualified rate more than 98%, if there have any issues, we will feedback to you once found, will provide best solution in shortest time. I found many people want looking for products in china, but they didn’t know how to find right products suppliers in China, it is hard to find right products suppliers. Also we provide you with factory price, just charge little service fees when order finished, we ensure that provide you with factory price, because of we have many direct factories, can get the price from factory boss. Nowadays, the dramatically competition happened on trade, dongsourcing agent dedicated to provide high quality and multiaspect services to the customers, help you creates valuable fortune.


The 3 types of sourcing companies in China

In other cases, you need to make a choice between three types of China sourcing companies:

The commissioned agent

If you find someone that you can trust, and who already has deep experience in the product line you are looking for, this can be a good option.These agents are seldom professional enough to really manage production and to ensure good outcomes. Once the orders reach a certain size, it is much better to manage everything with your own team.

The trading company

One of the important differences between sourcing companies and trading companies is that trading companies will have a high level of expertise in a specific field.

If you purchase low quantities and if you don’t want to handle all the details of Chinaproduction, you probably need to work with a trading company. What bothers some importers is that the supply chain remains hidden. This is a valid concern. Even if you purchase from a trader, you should inspect the product quality — except if the trader pays for a famous third-party QC firm to do it, and shows you the reports.

China Manufacturers

Manufacturers are often seen as the best and only source for your goods. You can communicate your needs directly with them and, if they are the right factory for you, they will have a high level of expertise in the manufacturing process.Factories will make products to your specifications and within the tolerances you demand. The factory you choose will have probably been making similar goods for some time.

Which Type is Right for You?

This decision is unique to each importer and is based on several factors, such as:

  1. Experience importing from China.
  2. Understanding and knowledge of import regulations and processes.
  3. Understanding of compliance requirements in the country where the goods will be sold.
  4. Size of your order – the total order value, as well as order value per product and per supplier.
  5. Resources available to manage the import process.

Still not sure which of type of sourcing agent is the right one for you? Contact us. We would love talking to you about your projects in China.
