Steel Pipe

Steel Pipe

Steel pipe is a long hollow cross-section material made of steel, divided into two categories: seamless pipe (hot-rolled/cold-drawn) and welded pipe (straight-seam/spiral-welded), which is used for transportation of fluids (water, oil and gas), manufacture of mechanical parts (shafts, drilling rods), and architectural support structures, and which is both lightweight and economic in nature.

Carbon Steel Seamless Pipe

Carbon Steel Seamless Pipe

Seamless carbon steel pipe is a hollow and seamless pipe made from carbon steel or low alloy steel through hot rolling, cold rolling or cold drawing process. Characterized by no seams, high compressive strength and light weight, it is suitable for transporting fluids such as oil, natural gas, water, etc. It can also be used for mechanical parts (such as transmission shafts, bearing bushings) and building structures.

Submerged Arc Welded Longitudinal Steel Pipe

Submerged Arc Welded Longitudinal Steel Pipe

LSAW pipe is a high-strength steel pipe made from steel plate, cold-formed by JCOE or UOE molding process, and then made by double-sided submerged arc welding technology. Its features include high weld quality, high pressure-bearing capacity, precise size, and materials covering carbon steel, low alloy steel and stainless steel. It is suitable for oil and gas transportation, building structures, bridges and machinery manufacturing and other fields, especially in the large-diameter (325-1420mm), thick-walled (10-100mm) pipe with outstanding performance. The global market continues to grow, with China as one of the major producing countries.

Spirally Submerged Arc Welding Steel Pipe

Spirally Submerged Arc Welding Steel Pipe

Spiral Submerged Arc Welded Pipe is a hollow pipe made of strip steel coil as raw material, which is spiral formed and then made by Double-sided Submerged Arc Welding process, featuring High Strength (compressive/bending resistance is better than that of straight-seam pipe), corrosion-resistant (surface anticorrosive treatment), and stable quality of weld seam (100% non-destructive testing). It is suitable for oil and gas transportation (over 4.0MPa pressure), water conservancy engineering (water supply and drainage), building structures (bridges/wharves) and chemical industry, low production cost and high production efficiency. The global market continues to grow, with China as an important producer, and the technology is developing towards high-strength materials, intelligent manufacturing and environmentally friendly processes.

Ductile Iron Pipe

Ductile Iron Pipe

We possesses the first level production lines with capacity of 940,000 tons DN80~DN2600mm annual production forductile iron pipe with T and Self-restrained joint.At present,we cansupply pipe with many kinds coating inside and outside,includingcement,zinc ,bitumen,epoxy,epoxy ceramic PE,polyurethane,FBEand so on,which are widely used to supply and drain water system

Casing Pipe

Oil casing is a key steel pipe that supports the wall of oil/gas wells. It is used to ensure drilling safety and normal oil and gas transportation after completion. It is a one-time consumable material (accounting for more than 70% of oil well pipe consumption). According to the steel grade, it is divided into J55, N80, P110, etc. The material includes carbon steel, alloy steel and anti-sulfur/anti-corrosion steel. It must meet the requirements of high strength, pressure resistance and corrosion resistance, and is suitable for different geological conditions and complex underground environments.

Stainless Steel Seamless Pipe

Stainless Steel Seamless Pipe

Stainless steel seamless pipes are hollow seamless long materials made of chromium-nickel stainless steel (such as 304, 316, 321, etc.) as raw materials, and are made of hot rolling, cold drawing or extrusion processes. They have corrosion resistance and high temperature and high pressure resistance. Its wall thickness uniformity is better than that of ordinary steel pipes, and is suitable for high-end fields such as petrochemicals (transportation of corrosive media), electricity (high-temperature steam pipelines), aerospace (lightweight components), and food and medicine (sanitary-grade fluid systems).

Stainless Steel Welded Pipe

Stainless Steel Welded Pipe

Stainless steel welded pipe is made of stainless steel strip (such as 304, 316, etc.) as raw material, through uncoiling, molding, welding, polishing and other processes made of hollow tubes, with strong corrosion resistance (self-repairing properties of the surface oxidation film), long service life, excellent hygiene (no red water / green water problems) and other characteristics. According to the process, it can be divided into straight seam welded pipe (high precision, uniform wall thickness) and spiral welded pipe (strong pressure-bearing capacity), which is widely used in the fields of chemical piping (acid and alkali resistant media), food and medical (sanitary fluid transportation), architectural decorations (handrails/screens), and mechanical structures. China is the main producer, global demand continues to grow, but high-end industrial pipes still need to be partially imported.

Stainless Steel Precision Tube

Stainless Steel Precision Tube

Stainless steel precision tubes are hollow seamless pipes made of chromium-nickel stainless steel (such as 304, 316, 321, etc.) as raw materials and are made of hot rolling, cold drawing or extrusion processes. They are characterized by corrosion resistance, high temperature and high pressure resistance, and excellent wall thickness uniformity. Its high accuracy (outer diameter tolerance can be controlled within 0.004mm) and finish (Ra0.4-1.0) make it suitable for high-end fields such as petrochemical industry (corrosive media conveying), aerospace (lightweight components), medical devices (surgical instruments, artificial joints), food industry (sanitary pipelines).

Galvanized pipe

Galvanized pipe

Galvanized steel pipe is a welded steel pipe and seamless steel pipe as a substrate, through the hot dip plating or electroplating process in the surface covered with zinc layer to enhance corrosion resistance of the pipe. Its zinc layer and the steel matrix to form a dense alloy structure, corrosion resistance up to 20 times that of ordinary steel pipe, widely used in water, gas, fire pipelines and building structural support, hot-dip galvanizing process because of the thick zinc layer (≥ 50μm) and long life (50 years in the suburbs, urban areas, 20 years) to become the mainstream.

Pipe fittings

Pipe fittings is a pipeline system to realize the connection, steering, diversion, sealing and other functions of the parts collectively, the common types include elbows (to change the direction of flow), tee (diversion), flange (removable connection), reducer (reducer) and so on. According to the material is divided into stainless steel, carbon steel, plastic, etc., widely used in chemical industry, construction, energy, water conservancy and other fields. The manufacturing process covers welding, casting, forging, suitable for different pressures and media requirements.
