FAQQ: You are manufacturer or trader?
A: we are manufacturer.
Q: Does your company steel pipe price high?
A: No, our production factory produce the goods by self and we export directly, no extra fees added.
Q: What factors have an effect on the price?
A: 1. the market, price rise and fall accompany with the market.
2. the goods grade, material and standard, different material(tolerance, chemical analyze) and standard with different price.
3. the steel pipe size, generally, fixed length is higher than random length, small size is higher than medium size.
4. the weight, actual weight is different to theoretical weight.
Q: How to shipment?
A: 1) Small diameter: Weight >Measurement
a. Length: ≤5.8m, loaded in 20FT Container, Max 27tons
b. Length: ≤11.8m, loaded in 40 FT Container, Max 27tons
c. Length: ≥12m, shipped by bulk vessel. FILO terms
2) Big diameter: Weight
b. Size of 40FT Container(inside:12024*2352*2395mm)
Q: How to packing?
A: Due to steel pipe belong to heavy goods, generally nude packing, strapped by steel strip in bundles or packed by woven bag. If you have special request, such as: plastic cap, black painted, we can help you do.
Q: What is your minimum order?
A: We do not have a minimum order. However, small qty will be waste for the shipping costs.
Q: Do you have inventory?
A: Yes, for normal size steel pipe, generally have in stock.
Q: If we only need our request size, can you offer?
A: Yes, we can customize the size for you.
Q: What's the application?
A: Generally, the carbon seamless steel pipe and alloy seamless steel pipe can divided into steel pipe for machine structural (auto parts, building)purpose and fluid purpose(water, oil, gas). The stainless steel pipe, due to corrosion resistance and high temperature resistance, generally used for ship railing, transport water,oil, chemical industry, architectural decoration , medical treatment, food, light industry, mechanical instrument etc.
Galvanized Steel Pipe can be made into a strong plumbing or tubing material -- one that resists corrosion from exposure to water or the elements.China Manufacturer Gold Supplier Pipe CS ERW Tube Seamless Steel Hot Galvanized Steel Pipe has been used used for water-supply pipes or as a strong tubing for outdoor applications.
USHDJ
Galvanized Steel Pipe is most commonly used for outdoor construction like fences and handrails, or for some interior plumbing. China Manufacturer Gold Supplier Pipe CS ERW Tube Seamless Steel Hot Galvanized Steel Pipe is also sometimes called galvanized iron pipe. Galvanized steel pipe has been coated with a layer of zinc. The zinc provides a barrier against corrosion so that the pipe may be exposed to the outdoor environmental elements.Galvanized Steel Pipe The protective barrier proves equally effective against damage from indoor humidity.China Manufacturer Gold Supplier Pipe CS ERW Tube Seamless Steel Hot Galvanized Steel Pipe is covered with a zinc material to make the steel pipe more resistant to corrosion.
