q345 cold drawn pipe with more than 20 years experience

Established in December 1992, Yantai Xinpeng Steel Pipe Co., Ltd. has been specialized in this line for more than 20 years.

During the past 20 years, Xinpeng produces various kinds of seamless steel pipe, which can be widely used for hydraulic cylinder for automobile,engineering machinery, excavator, forklifts etc.

Xinpeng are equipped with JLB250T hydraulic cold drawn set, LD120 cold rolling set, annealing furnace,strong honed machine, polishing machine, lathe, saws CNC skived and roller burnished machine, kinds of testing machine.Strictly comply with the ISO9001 System, assure the best quality of the products.

Products

(1)cold drawn/rolled pipes

Grade: 20#  45#  Q345B  Q345D  25Mn  27SiMn  E355  SAE1026

Standard: GB/T8713  GB/T3639  DIN2391  EN10305  ASTMA519

Range: 30-300mm

Length: 11m(max)

The cold process can improve the machanical property of the pipes and offer better tolerance.

(2)SRB&Honed Tube

ID Tolerance: H8  H9

ID Roughness: RA0.4micron(max)

Length: 6m(max)

This process can improve the roughness of the inner tube with roughness 0.2-0.4um.

The difference between precision steel pipe and seamless pipe?

 1. the seamless steel tube with obvioue difference is that dimensional accuracy, can be up to 0.1mm.

 2. high precision steel pipe diameter surface finish, the customer without processing can be used directly and ordinary seamless steel tube to the customer and lather, polishing processing.

 3.Superior surface finish

 4.Dimensional accuracy and excellent micro-structure uniformity

Certificate

Strictly according to system verified ISO9001:2008, all our products are in high quality control and tight tolerance.

 Packing

1. bundle packing

2. marking as per customer's requests

3. paint on the pipe as per customer request

4. pipe caps as customer request

Delivery condition

1. NBK(+N)

after cold forming, eventually above phase transition point, in a protective atmosphere of annealing oxidation medium

2. GBK(+A)

after cold forming, annealing in non oxidizing medium protective gas

3. BK(+C)

the final heat treatment after cold forming, therefore small steel pipe plastically, the plastically degree does not guarantee

4. BKW(+LC)

after final heat treatment, a tiny cold drawing deformation, continue again when machining steel pipe allowed inside certain limits cold deformation(bending, flaring)

5. BKS(+SR)

have a stress relief after cold forming, heat treatment, steel pipe can be carried out within a certain limit in the appropriate processing

Application

Service

1. Cargo track service during transporting and feedback service after cargo is loaded on board

2. Flexible terms of payment by T/T , L/C And so on.

3. Big discount for repeat customers

4. Smooth delivering procedure

5. More than 20 years steel trading experience

6.Alibaba trade assurance supplier

FAQ

Q1.What do you want to purchase ?

What we can offer are cold drawn seamless tubes,cold drawn welded tubes (DOM tubes)

Q2.Do you have the target price ?

 Generally ,we have the target price when we buy something ,which is good for both supplier and

 customer ,at the same time ,the target price should be objective ,reflecting the market.

Q3.What factors have an effect on the price ?

 1 The market. our price rise and fall accompany with the market

 2 The material and the grade .Different materials sometimes mean hundreds dollars.

 3 The sizes. generally ,the thinner is more expensive because of the manufacture difficulty
