Pipe wrench is used to clamp and rotate steel pipe class workpieces. It can be divided into various types according to bearing capacity, weight, style, etc., and is widely used in oil pipeline and civil pipeline installation.Clamp the tube and turn it to complete the connection. Its working principle is to convert the clamping force into torque, and the force used in the direction of twisting is tighter.

Increase the torque with the taper of the jaws, usually 3-8 degrees, to hold the tube. Automatically adapt to different pipe diameters, and automatically adapt to the plastic deformation caused by the stress exerted on the pipe by the jaws. Under the effect of reducing the pipe diameter, the torque is guaranteed without slipping. Ex tool manufacturer

The material of non sparking tools: Al-Br(QAl11-4-4), Be-Cu(QBe2)

Be-Cu: the color is green lake,hardness is not less than HRC35,tensile strength δ b 105-120kgf/mm2;standard code GBEX ⅡC,suitable for hydrogen with concentration 21.0±2.0%.Beryllium copper alloy with anti-magnetic performance.

Al-Cu: the color is bluish yellow,hardness is not less than HRC25,tensile strength δ b 75-85/mm2;standard code GBEX ⅡB,suitable for ethylene with concentration 7.8±0.5%,GBEX ⅡA (propane 6.5±0.5%),Ⅰ(methane 6.5±0.5%)。

Non sparking tools of XIN DA are made of high strength copper alloy.This kind hand tools can effectively prevent burning and explosion accidents caused by friction and collision between tools and tools in the flammable and explosive workplace.The explosion-proof performance received the certificates according to the national standard GB10686-2003, with the function of high intensity and good toughness.

The products are widely used in petroleum,chemical industry,mining,gas,coal,oxygen-producing,pharmacy,smelting,powder,leather,airplane,marine engineering etc,suitable for warehouse that operate flammable and explosive products,electrolytic workshops,communication assembly workshops,and requires that the tools are not rusty,wear-resistant and anti-magnetic during the checking process.
