General introduction

The steel for both seamless and welded pipe shall be made by one or more of the following processes: open-hearth, electric furnace, or basic-oxygen. The weld seam of electric-resistance welded pipe in Grade B shall be heat treated after welding. Seamless steel pipe is one of the most important product for iron and steel industry. With the development of industrial technology, the seamless steel pipe become more and more important in defense industry, science technology and economic development. And it becomes the main material for mechanical and architectural structure.

Q: 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 a. Size of 20 FT Container(inside:5898*2352*2350mm)
b. Size of 40FT Container(inside:12024*2352*2395mm)

Q: How to packing?

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.

Seamless Steel Pipe mills, volume should go through continuous annealing (CAPL unit) to eliminate cold hardening and rolling stress, or batch annealing reach the 23mm seamless steel pipe tube/ 300mm diameter galvanized steel pipe mechanical properties of the corresponding standard specifies. Seamless Steel Pipe surface quality, appearance, dimensional accuracy 23mm seamless steel pipe tube/ 300mm diameter galvanized steel pipe better than hot-rolled plate, and right-rolled thin product thickness is about 0.18mm, so the majority of users favor.
