Pup Joint is a pipe that can be cut into different lengths such as 2ft, 4ft, 6ft, 8ft etc. It's always used to connect 2 casing pipes or tubings to reach the exact required length. 

Pup Joints can be classified into two types. One comes with male threads at both ends. The other type comes with male and female threads at each end. Or we can call these 2 types as: Pin x Pin & Pin x Box.

Galvanized steel pipe belongs to one kind of steel pipes with surface treatment on the pipes, which is named as galvanization. Galvanization (or galvanisation) is the process of applying a protective zinc coating to steel or iron, in order to prevent rusting. The term is derived from the name of Italian scientist Luigi Galvani

Galvanized steel pipe is generally connected by threads on either end of a length of pipe. A small amount of adhesive is typically placed on the threads before screwing them together, in order to reinforce the connection. If no threads are available, the pipes and fittings can be welded together, although caution should be taken because the heat from welding can release dangerous zinc fumes into the air. Pipes can be cut using a cutoff saw or hacksaw.

Hebei Borun Steel Trade Co.,Ltd is a professional supplier & exporter of galvanized steel pipes, seamless pipes and oil casing pipe in China. With more than 15 years experience in steel pipe filed, we are capable of providing customer steel products with good quality and reasonable prices. Small Order, Fast Delivery, Good Quality, Competitive Price is our operation concept.

More over we are OEM for TPCO, BAOSTEEL, LUBAO, which greatly give us more access to finish large orders with complicated specifications.

Galvanized Carbon Steel Pipes are one of the leading products in our company.

Seamless steel pipes, as one kind of the most important steel pipes, are often seen to be widely used in fluid transport, oil field, natural gas, constructions, shipbuilding, machinery, chemical industry, electricity industry etc.

There are mainly 2 types seamless steel pipes as per production technology: Hot Rolled Seamless Pipe & Cold Rolled Seamless Pipe

For hot rolled seamless pipe, the production process is: steel billet-heating-punching-three-roll cross rolling, continuous rolling –detaching pipe-sizing or reducing-cooling-straightening- hydrotest (NDT)- marking-warehouse entry

Specification Range:

1 OD: 3''-24'' (73mm-610mm)

WT: SCH10-SCHXXS

2 Materials: 10#, 20#,45#, 20G,16Mn, GRB, Q345B, X42-56, ST44, ST52，S355 etc.

3 Standards: GB/T8162/8163/3087/5310, ASME B36 10, ASTM A106/A53, API 5L/5CT, DIN2448/1629, EN10210/10219

4 Testing: Eddy current, Hydrostatic, Ultrasonic, Intergranular corrosion etc.

5 Packing: in bundles with steel strips, seaworthy packing as per customer's requirements

For cold rolled seamless pipe, the production process is: steel billet-heating-punching-head making-annealing-cooper plating-cold drawing (cold rolling)-semi-finished pipes-heat treatment-straightening-hydrotest(NDT)-Marking-warehouse entry

1 Specification range:

OD: 1/8''-5'' (10.3mm-141.3mm)

WT: SCH10-SCHXXS

2 Materials: 10#, 20#,45#,16Mn, GRB, Q345B, X42-56, ST44, ST52 etc.

4 Testing: Eddy current, Hydrostatic, Ultrasonic, Intergranular corrosion etc.

5 Packing: in bundles with steel strips, seaworthy packing as per customer's requirements

The largest benefit to using seamless steel pipe is the increased pressure ratings. When steel pipe is rolled and welded, the weakest point in the pipe is the welded seam. A seamless steel pipe does not have a seam, so the tensile strength is uniform around the entire circumference of the pipe. Steel pipe has nominal pressure ratings that are based on the tensile strength of the alloy (mixture of metals) and the wall thickness of the pipe. Using seamless pipe is more expensive but allows for smaller wall thicknesses and pipe weight, which can affect design and costs.

Hebei Borun Steel Trade Co.,Ltd is a professional manufacturer & supplier of seamless steel pipes in China. With almost 15 years in this field, we are capable of providing customers seamless pipe with good quality and competitive price. Located in the center of steel pipes and pipe fittings, we can source any kind of steel pipes with Small Order, Complex Sizes in the earliest time. More over, since we are near to Tianjin and Beijing, the charges in every aspect is less accordingly.

Square tube ( we can name it as square pipe or square hollow section) is one kind of steel pipes. The first obvious difference with other common steel pipe is that the cross section is square or rectangular instead of round. 

Nowadays square tubes are widely used in constructions, machinery, shipbuilding, airport, steel frames etc. 

And most customers prefer to choose square tube instead of round tubes when it comes to the constructions, steel structures. 

Hebei Borun Steel Trade Co.,Ltd is a professional supplier & exporter of square tubes in China. With more than 10 years experince in this field, our products have been exported to almost 50 countries in the world. We have 5 production lines which  gives us a good access to finish large orders in the earliest time . Meantime we are now OEM for some famous brands such as TPCO, BAOSTEEL, LUBAO, which provides us raw material with good quality and competitive price .

There are ERW & SMLS types here.
